You can type custom names and edit channel maps in seconds. Clear labels reduce mistakes and make daily operation simpler for everyone in the home.
Up to 30 virtual inputs let you pair video from one source with audio from another. This supports practical workflows like game-day radio overlays or listening to another room while watching TV.
- Access: use device IP to open full web setup.
- Quick tasks: name inputs, assign channels, and manage ARC profiles.
- Profiles: save multiple speaker scenes for A/B listening or different seating.
- HDMI: EDID-friendly naming keeps source selection intuitive.
- First-boot tip: network, name inputs, set layout, check levels, run ARC Genesis planning.
Anthem Room Correction: ARC Genesis in the Home
ARC Genesis simplifies calibration with a guided workflow that turns complex acoustics into practical, repeatable correction. Connect the supplied calibrated microphone, place it at a set of listening positions, and run the guided sweeps to build an accurate model of your room.
Calibration workflow and the redesigned microphone
Use the mic exactly as instructed. The redesigned microphone carries an orientation dot to improve spatial capture. Correct placement sharpens midrange and crossover corrections where dialog lives.
Multi-profile presets and practical presets
The system supports multiple profiles: single-seat for critical listening, couples, full-room smoothing, and a late-night mode that reduces low-frequency energy without killing impact.
Tuning philosophy: defaults vs Pro-mode
Automatic targets stay conservative and balanced; they deliver reliable results with minimal tweaking. A Pro-mode is available for users who want to tilt targets, but use caution at response extremes to avoid taxing speakers or subs.
- Productivity: open and edit ARC files offline, compare two sessions side-by-side, then upload changes quickly.
- Best practices: use multiple mic heights, 6–8 positions, and consistent sweep counts to reduce variance.
| Feature | Benefit | Result |
|---|---|---|
| Orientation dot | Better mic placement | Improved spatial correction |
| Multi profiles | Flexible listening scenes | Consistent dialog and bass |
| Offline editing | Faster iteration | Quicker final tuning |
Listening Tests: Sound and Video Without ARC
Controlled playback began with precise two-channel music to expose the unit’s intrinsic tonal balance. Laser-measured distances and fixed SPL targets isolated the electronics from room effects. This baseline method lets the hardware speak before any correction.
Stereo music as a baseline: preamp stage and power authority
Stereo tests revealed a fuller, more authoritative presentation than the prior generation. The preamp and amplifier sections showed clearer midrange weight and tighter transient control. Across dynamic peaks the unit stayed composed, thanks to a low-noise preamp architecture that keeps the background quiet.
HDMI stability, codec behavior, and video pass-through
Day-to-day HDMI work was solid. Cable boxes, streamers, and a finicky Xbox all locked codecs reliably with no snow, dropouts, clicks, or pops during long sessions. Video pass-through preserved Dolby Vision on supported sources and avoided handshake loops or resync delays.
The uncorrected timbre and staging were notable: centered vocals, steady imaging, and respectable bass grip that hints at what calibration will tighten. Tests across trailers, concert films, and playlists produced consistent, repeatable results—an underrated trait in any home theater test.
| Subject | Observation | Implication |
|---|---|---|
| Two-channel music | Richer midrange, authoritative delivery | Improved preamp and power design |
| Dynamic handling | Calm at peaks, low noise floor | Good headroom for complex mixes |
| HDMI & video | Stable codec lock, clean pass-through | Reliable daily use with varied sources |
Performance With ARC: Dynamics, Soundstage, and Bass Control
After ARC completes, the difference is immediate. Many listeners say the room feels larger and more immersive. The front-to-back depth becomes cleaner, and effects wrap around the listening area.
How ARC changes imaging and cohesion
How target filters smooth peaks and nulls
ARC applies measured target filters that reduce room-induced peaks and fill nulls. That smoothing unlocks a noticeably wider staging and better envelopment in immersive soundtracks.
Dialog and front-stage focus
Center clarity without cranking the center channel
After calibration, center-channel intelligibility improves. Dialog sits in the mix naturally, so you avoid boosting the center speaker and keep tonal balance intact.
Bass integration and crossover behavior
Automatic crossovers for seamless speaker-sub blending
ARC’s automatic bass management usually nails integration between mains and subs. That reduces localization and gives more even bass across the room. Crescendos feel cleaner and impact is preserved at the same master volume due to fewer room resonances.
Music benefits and practical tips
When to trust automation and when to tweak
Music playback gains tighter bass lines and clearer image placement. Trust the automatic crossover in most setups. Experiment only if you use unconventional speaker/sub combos or want a specific tonal range.
Profiles and listening modes
Quick A/B with multiple ARC profiles
Saved profiles make it simple to compare tonal balances for late-night mode or full-room listening. Switching profiles is fast, so you can match the system to the occasion.
| Effect | What ARC does | Result |
|---|---|---|
| Staging | Smooths peaks/nulls across frequencies | Wider, more enveloping soundfield |
| Dialog | Aligns timing and EQ on center | Clearer speech without center boosts |
| Bass | Auto crossover and low-frequency smoothing | Even bass, fewer localization issues |
| Dynamics | Reduces room resonance, improves time coherence | Cleaner crescendos and preserved impact |
Bench Data and Power: What the Measurements Reveal
Objective tests map the receiver’s output, noise floor, and amp headroom under load.
Preamp performance stands out. Preouts deliver over 5 Vrms unclipped with vanishing distortion (
Amplifier and channel behavior
Class AB bed amplifiers produce ~145 W/channel single‑ended and ~130 W/channel two‑channel into 8 Ω at
Height amp characteristics and inputs
Class D height amps meet rated output (~70 W/ch two‑channel) with a limited bandwidth (≈20 Hz–17 kHz), ideal for presence duties. Analog inputs are digitized at 96 kHz; ADCs keep bandwidth to ~50 kHz and THD+N <0.01% at 20 kHz.
| Metric | Measured Result | Listening Impact |
|---|---|---|
| Preout voltage | >5 Vrms, | Drives external amps with headroom |
| SNR / SINAD | 110 dB @2 Vrms / ~105 dB SINAD | Very low noise, clean dynamics |
| Crosstalk | 95 dB @1 kHz, >70 dB @20 kHz | Strong stereo separation across channels |
| Power (bed) | 130–145 W/ch steady, 212 W bursts | Ample headroom for music and film peaks |
What this means: test data shows a transparent signal path, low noise, and robust amp range. For demanding mains or low‑impedance loads, consider efficient speakers or adding external amplifiers to protect against current limiting.
Bass Management, Subwoofer Options, and “Super Sub Fronts”
The latest firmware adds a 24 dB/octave low-pass on the sub output, with the -6 dB point set at the selected crossover (for example, 80 Hz). This change reduces overlap and yields cleaner summation when you use a typical 80 Hz crossover.
Slopes and speaker integration
The system still applies a 12 dB/oct high-pass to bass-managed speakers. That pairing — 12 dB HPF on mains plus 24 dB LPF on subs — creates a smoother transition and steadier in-room response.
“Super Sub Fronts” behavior
Super Sub Fronts lets subs play alongside full-range mains. In two-channel mode, if you leave mains full-range, the sub defaults to a 40 Hz LPF. Enable this only when you want mains to remain unfiltered and let subs add extension for music.
Setup checklist and differences
Choose a sensible crossover (often 80 Hz), confirm phase and level, then run ARC Genesis so room correction refines integration across multiple mic positions.
The MRX 740 offers dual linked sub outputs; the larger model provides independent sub outputs with separate level/phase and ARC calibration. Use independent outs when two subs sit in asymmetrical rooms for better seat-to-seat uniformity.
| Step | Why | Quick result |
|---|---|---|
| Set crossover (80 Hz) | Standard blend point | Smoother handoff |
| Confirm phase & level | Align timing | Clearer low end |
| Run ARC Genesis | Apply room correction | Even bass across seats |
Amp Matrixing and Channel Strategy for Dolby Atmos Systems
Amp matrixing lets you reassign onboard amps so a single receiver adapts as you add external amplification.
Use the web UI to map outputs logically. The interface allows flexible roles: Front can become Front Wide or Height 3; Surround can serve Height 3; Back supports Front Biamp or Zone2. Height1 and Height2 also accept Zone2 or biamp roles.
Practical channel allocation
Prioritize Class AB channels for the front stage and main surrounds. Those channels offer higher current and better dynamic headroom for the speakers that carry most of the load.
Assign Class D modules to heights or Zone 2. This is an efficient way to use internal amp resources without stressing the power supply.
Bi-amp caution and expansion plan
Do not bi‑amp main speakers using internal Class D modules. That approach causes about a 3.7 dB dynamic range penalty. For LCR or heavy mains, use a dedicated external amplifier instead.
Start with internal amps powering heights. Later add a 3‑ to 5‑channel external amp for bed channels when you need more continuous power.
Step‑by‑step reassignment in the web UI
- Open the receiver’s IP and enter Amplifier Assign.
- Label each output (Front, Surround, Back, Height1, Height2).
- Choose the role for each output (e.g., Height, Zone2, Front Biamp).
- Save and reboot the amp matrix to apply changes.
After reassignment, verify levels and delay for each channel. Re-run ARC Genesis so the audio filters and crossover settings match the new topology.
| Use Case | Recommended Channels | Why |
|---|---|---|
| 5.1.4 small room | Front: AB, Surround: AB, Heights: Class D | AB for core imaging; D for heights saves power for bed channels |
| 7.1.4 larger room | Front/Surround: AB or external amp, Back: AB, Heights: Class D | External or AB ensures headroom across multiple listening rows |
| Bi-amp LCR | Use external multi‑channel amp for bi-amping | Avoid Class D internal bi-amp to preserve dynamic range |

Anthem MRX 740 Review: Value, Comparisons, and Who Should Buy
Deciding between compact power and higher channel count hinges on practical needs, not just headline specs.
MRX 740 vs MRX 1140: channels, power supply, sub outs, and headroom
Processing and amps: The smaller unit provides 11 channels of processing and seven onboard amps (five 140 W AB channels and two 60 W channels). The larger model ships with 15 channels of processing and 11 onboard amps (five 140 W + six 60 W), which makes it easier to run 7.1.4 or 9.1.4 without extra hardware.
Subwoofer outputs: The compact unit uses dual linked sub outs, which simplifies setup but limits independent level or delay per sub. The bigger model offers independent dual sub outs for tighter seat-to-seat consistency in asymmetric rooms.
Power supply and headroom: The smaller unit uses an E-core transformer; the larger one uses a toroidal supply. Lab data favor the toroidal design for slightly better two-channel power and lower power-supply harmonics when driving hard.
Best speaker matches, room sizes, and upgrade paths
For speakers, the internal amps pair best with efficient towers or bookshelf speakers (nominal ≥6 Ω). If your mains are low-impedance or low-sensitivity, plan to add external amplification for the front stage.
Room guidance is straightforward: the unit shines in small-to-medium rooms at typical listening levels. For larger rooms or high SPL targets, the larger model or added external power is the safer choice.
Common upgrade path: start with the compact unit, add a 3- or 5-channel external amp for the LCR, reassign internal amps to heights via the web UI, and re-run ARC Genesis to match filters and crossovers.
| Factor | Compact unit | Larger model | When to pick |
|---|---|---|---|
| Processing channels | 11 | 15 | Pick larger for full 9.1.4 without extras |
| Onboard amplification | 7 channels (140 W x5, 60 W x2) | 11 channels (140 W x5, 60 W x6) | Choose larger if you need more internal amps |
| Sub outputs | Dual linked | Independent dual outs | Independent outs aid multi-sub tuning |
| Power supply | E-core | Toroidal | Toroidal reduces harmonics, gives marginally more two-channel power |
Value summary: The compact unit delivers high-quality preamp features and calibration that approach separates, making it a smart choice for buyers who want strong performance and a sensible price. Add targeted external power as needs grow for the best long-term performance.
