Head-to-head

Marantz CINEMA 50 vs Onkyo TX-RZ50: Marantz separates sub settings, Onkyo’s front HDMI has stricter video limits

The short answer

Choose CINEMA 50 for separate level and distance settings on two to four powered subs, with matching Speaker Layout and output 4 reserved when using four. Rear HDMI access or a tested extension must suffice. Choose TX-RZ50 for accessible front HDMI in the main room when shared sub settings suffice and source, cable and display qualify. Front 4K60 requires 8-bit YCbCr 4:2:0, with no 4K120, 8K or HDMI Zone 2. Both support properly assigned 5.1.4. Neither powers 7.1.4 without an external two-channel amplifier or combines both distinguishing features.

Before you choose

The reasoning and the trade-offs

Two subs can need two settings even when the socket count looks sufficient

Two differently placed powered subs may need different receiver level and distance settings. CINEMA 50 provides them with matching Speaker Layout, while Onkyo’s second socket repeats the shared signal and setting. With one sub, or a verified external processor already handling adjustment, the receiver advantage can disappear. Rear HDMI access or a tested extension must still suit you. No smoother-bass result is established.

What this is based on

Both manuals explicitly describe their subwoofer outputs. Marantz also documents Standard and Directional routing, and requires Standard for Audyssey Sub EQ HT. Its distance display changes to milliseconds under Dirac Live. Those distinctions prevent separate settings from becoming a claim about equivalent or superior correction methods.

Main trade-off

About this comparison

Compare Marantz CINEMA 50 subwoofer controls with Onkyo TX-RZ50 front HDMI access, including video limits, room routing and setup requirements.

Both receivers can anchor a main-room system with five ear-level speakers and four heights. The choice here is about two different jobs. Marantz lets you set multiple powered subs separately inside the receiver. Onkyo brings a suitable visiting HDMI source to the front. The useful feature depends on what you actually connect and how you can reach it.

Winner by situation

Start with what you need it to do

  • Two powered subs need separate receiver settings and rear source access is acceptable

    Marantz supplies separate level and distance entries for two to four powered subs with matching Speaker Layout. For four, output 4 must remain a sub output. Rear HDMI access or a tested extension must fit the source routine. Onkyo’s second socket cannot satisfy this control requirement, which is not proof of better bass.

  • A visiting camera uses a supported front-port signal and stays in the main room

    Onkyo avoids rear access for a main-room source if the front flap and plug are reachable and one or two powered subs can share one receiver setting. Verify the source, cable and display. Front 4K60 needs 8-bit YCbCr 4:2:0, with no 4K120, 8K or HDMI Zone 2. A suitable tested Marantz rear extension can remove the practical gap.

  • One sub, permanently connected HDMI sources and a documented 5.1.4 main-room layout

    With compatible source-to-display connections, the correct speaker assignment and a ventilated installation, both cover this plan. Separate sub settings and a front socket do not decide it. Compare the other functions you actually use and current complete offers. No equal sound quality or lower price is assumed.

  • Separate receiver sub settings and a built-in front HDMI socket are both mandatory

    Marantz has the separate settings but only rear HDMI inputs. Onkyo has front HDMI within its signal and main-room limits, but shared sub settings. Neither supplies both unchanged. A tested rear extension changes the access requirement rather than adding a front socket.

  • The front HDMI source must feed the separate-room HDMI Zone 2 TV

    Marantz has no front HDMI input. Onkyo’s HDMI Zone 2 accepts only rear HDMI IN 1 to 3 with two-channel PCM and Zone 2 HDMI set to Use. Its front AUX camera route cannot meet this requirement. Reconnecting the source at a compatible rear input changes the plan.

  • Seven ear-level speakers and four heights must run without an external amplifier

    Both need an external two-channel power amplifier and the documented assignment for 7.1.4. Neither the subwoofer socket count nor the presence of front HDMI adds powered main-speaker channels. A 5.1.4 plan is the supported all-in-one alternative if fewer ear-level speakers are acceptable.

What matters in practice

The differences that matter

Two subs can need two settings even when the socket count looks sufficient

Two differently placed powered subs may need different receiver level and distance settings. CINEMA 50 provides them with matching Speaker Layout, while Onkyo’s second socket repeats the shared signal and setting. With one sub, or a verified external processor already handling adjustment, the receiver advantage can disappear. Rear HDMI access or a tested extension must still suit you. No smoother-bass result is established.

How we reached this conclusion

Both manuals explicitly describe their subwoofer outputs. Marantz also documents Standard and Directional routing, and requires Standard for Audyssey Sub EQ HT. Its distance display changes to milliseconds under Dirac Live. Those distinctions prevent separate settings from becoming a claim about equivalent or superior correction methods.

The front connection helps only when the visiting signal fits

A camera that comes out occasionally can avoid a reach behind Onkyo. That benefit needs an accessible flap and plug, a main-room route and one shared receiver setting for one or two powered subs. The source, cable and display must qualify. Front 4K60 requires 8-bit YCbCr 4:2:0, without 4K120, 8K or HDMI Zone 2. A tested Marantz rear-input extension can erase the access difference.

How we reached this conclusion

Onkyo explicitly documents a front camera connection and AUX selection. Its front-input format table is narrower than the rear-input table, and its HDMI Zone 2 instructions accept only rear inputs 1 to 3. This is an access benefit under specific signal and routing conditions, not evidence of universal plug-and-play compatibility.

If both jobs are mandatory, neither does everything by itself

Neither meets both requirements if separate receiver sub settings and built-in front HDMI are mandatory. A verified rear-input extension relaxes the access requirement for Marantz. Accepting shared sub settings relaxes the calibration requirement for Onkyo, whose front format and main-room restrictions remain. If neither compromise works, change the shortlist. Separately, both need an external two-channel amplifier for 7.1.4.

How we reached this conclusion

The two requirements can change independently. An extension changes access, while a shared sub setting changes the calibration plan. Neither substitution is assumed to be acceptable or included. The manuals separately document the external-amplifier requirement for eleven main-room channels.

Two Onkyo sockets do not provide two separately adjustable receiver outputs. This is a control difference, not a measured bass result.
Connecting a visiting HDMI sourceHDMI inputs are on the rearAUX INPUT HDMI behind the front flapOnkyo avoids reaching behind the receiver when the front is accessible. Marantz can lose that practical disadvantage if an appropriate rear-input extension already reaches the visitor and works with the required signal.
Video formats for the front connectionNo front HDMI input4K60 only at 8-bit YCbCr 4:2:0Do not move a 4K120 or 8K source to Onkyo’s front jack expecting the rear-input capability. Its listed 4K30 options include 8-bit RGB, but 4K60 RGB is outside the front-port table. The source, cable and display all need the chosen format.
Sending that front source to another roomNo front HDMI input to routeFront AUX is excluded from HDMI Zone 2The convenient camera connection is a main-room benefit. Onkyo’s HDMI Zone 2 route accepts only rear HDMI IN 1 to 3 and requires two-channel PCM audio. A second display in the main room uses a different output setting.
Room around the receiverNeeds ventilation and rear cable accessNeeds ventilation, rear cable access and front-flap space for AUXA chassis fitting a shelf is not enough. Leave the ventilation space required by the supplied installation instructions and room for cables. A closed cabinet door or obstructed flap can remove the Onkyo access benefit.

What you give up

Every choice has a cost

If you choose Marantz CINEMA 50

  • Separate sub settings require the matching Speaker Layout. Audyssey Sub EQ HT needs Standard mode, and output 4 cannot serve a fourth sub when used for a tactile transducer. No bass-quality advantage is established.

If you choose Onkyo TX-RZ50

  • Front AUX needs an accessible flap, compatible source, cable and display, and a main-room output route. Front 4K60 requires 8-bit YCbCr 4:2:0. It excludes 4K120 and 8K and cannot feed HDMI Zone 2.

Recommendation switch

The decision flips if...

Separate receiver settings for multiple powered subs are the requirement

Choose Marantz CINEMA 50. Multiple powered subs favor Marantz when separate level and distance settings are genuinely needed. Set Speaker Layout for two to four connected subs and keep output 4 for a sub if using all four. Rear HDMI access or a tested extension must suffice. The settings alone establish no bass-quality improvement.

A supported main-room visiting source needs easy front access

Choose Onkyo TX-RZ50. Frequent main-room source changes favor Onkyo if its front flap and plug remain accessible and shared settings suffice for one or two powered subs. The source, cable and display must match: front 4K60 needs 8-bit YCbCr 4:2:0, with no 4K120, 8K or HDMI Zone 2.

Separate receiver sub settings and built-in front HDMI must be present together

Choose neither. Neither combines them. Marantz offers separate settings with rear HDMI. Onkyo offers front AUX with shared sub settings and restricted formats and routing. Consider another model unless one of those requirements can change.

The built-in front socket must accept 4K120 or 8K, or feed HDMI Zone 2

Choose neither. Marantz has no front HDMI. Onkyo’s front table excludes 4K120 and 8K, and HDMI Zone 2 uses only rear inputs 1 to 3. Choose a suitable rear path or another documented connection plan.

You require 7.1.4 without an external power amplifier

Choose neither. Both require an external two-channel amplifier for that layout. Choose a receiver that powers all eleven main channels, or change the speaker plan to a documented self-powered layout such as 5.1.4.

What matters in practice

Before you choose

First confirm the speaker plan and a ventilated installation. Then decide whether separate receiver settings for your subs or an accessible, compatible visiting-source connection solves the real problem.

Check these before buying

  • Confirm the original US Marantz CINEMA 50 or Onkyo TX-RZ50, with the selected package and included calibration microphone. CINEMA 50 Series 2 and other RZ models are different products. Check the current seller, condition and return terms. No current stock, price or delivery promise is made here.
  • For five ear-level speakers and four heights, follow the exact 5.1.4 wiring and amplifier assignment. If you want seven ear-level speakers and four heights, budget for an external two-channel power amplifier and use the documented 7.1.4 connections. Powered extra-room speakers can change available main-room channels, so check the simultaneous layout rather than counting terminals.
  • Connect powered subs to their receiver pre-outs. On CINEMA 50, set Speaker Layout to two, three or four subs as actually connected, then use the separate level and distance entries. With Dirac Live, distance entries use milliseconds and are stored by filter. Unplug headphones before using its Levels test tones. If output 4 serves a tactile transducer, it is not also a fourth subwoofer output.
  • Marantz’s Standard subwoofer mode sends LFE and the redirected bass from all speakers to every sub. Directional changes which redirected bass goes to which sub. Audyssey Sub EQ HT requires the appropriate two-, three- or four-sub measurement choice and Standard mode. It does not run in Directional. Separate settings are not proof that either mode or correction system sounds better.
  • On TX-RZ50, both sub sockets share the signal and the receiver has one subwoofer distance and level entry. After Dirac Live measurements, its distance values are shown in milliseconds and cannot be changed there. Controls on the powered subs or additional external hardware are separate from independent controls inside this receiver.
  • For Onkyo’s front AUX, compare the source’s actual output with the manual’s front-input column. For 4K at 24, 25 or 30 Hz it lists 12-bit YCbCr 4:2:2 or 8-bit YCbCr 4:4:4/RGB. At 48, 50 or 60 Hz it lists only 8-bit YCbCr 4:2:0. It lists no 4K100/120, 5K or 8K front support. A laptop sending 4K60 RGB therefore needs another supported output setting or a suitable rear input.
  • Open Onkyo’s flap, allow space for the HDMI plug and cable, and choose AUX for the front source. Verify the cable, display and source together. For a normal main-room screen, use the corresponding HDMI Out setting. If MAIN and SUB are both selected, different display resolutions limit the shared output to the lower resolution. The front input cannot supply HDMI Zone 2, which uses rear HDMI IN 1 to 3, two-channel PCM and Zone 2 HDMI set to Use.
  • Measure the installed depth with rear plugs, the space to open the front door or flap, and the ventilation clearance required in the supplied safety instructions. Both manuals warn that excessive temperature can trigger shutdown. Do not infer safe cabinet clearance from bare chassis dimensions or block airflow to keep the front tidy. A tested extension to a Marantz rear input can change the access decision, but is an additional cable to verify for the required format.

What this comparison cannot tell you

  • This comparison uses exact-model operating instructions and published connections. It does not establish a hands-on sound-quality, bass-smoothness, room-correction, amplifier-power, latency or reliability winner.
  • Four sockets alone would not prove independent control. Marantz’s explicit separate level and distance instructions establish that capability. They do not establish independently optimized bass at every seat or make sub placement unimportant.
  • The Onkyo front HDMI port is useful only for signals and output routes it supports. Its lower-bandwidth format table cannot be replaced by the headline capabilities of the rear HDMI inputs. No arbitrary camera or laptop compatibility is promised.
