Anthem MRX 300 - Design and Connectivity
Anthem is a Canadian AV brand that specialises in high-end, performance-driven
power amps, processors and AV receivers, and is distributed in the UK by the same
company that brought us the brilliant Paradigm Cinema CT 100 speaker system
(Anthem AV Solutions).
On test here is the Anthem MRX 300, an entry-level AV receiver aimed at a more
mainstream market, but when an entry-level product comes with a price tag of over
£1,000, you know you’re still deep in high-end territory.
The Anthem MRX 300 is very much aimed at enthusiasts, not only because of its
focus on performance but also because it’s bundled with more advanced calibration
software than you’d normally expect to find with an AV receiver.
On the downside, it eschews frills like networking functionality, internet radio and
USB music playback (the last two are reserved for the step-up MRX 500 and MRX
700, £1,599 and £2,099 respectively) but still has a decent-looking spec, with 7 x
80W of power, decoding for all the major audio formats, 3D support and a whole
host of listening modes.
Anthem MRX 300 Design
What you also get for the money is impressive build quality. Lifting it from the box
you can feel the heft and solidity of the metal bodywork, while the thick brushed
aluminium front panel and firm controls add to the overall sturdiness.
The front panel is busy, with controls dotted all over the place, including a direction
pad for controlling menus, direct input selection keys and a chunky volume dial.
There’s also a large display panel that by default gives volume, source and format in
large blue letters, but can be used to view the setup menus too. Towards the
bottom is a recess that runs the width of the front panel, which houses composite
and analogue stereo inputs, plus a headphone jack – all covered by a sliding panel.
The lack of front digital inputs or HDMIs is a bit of a shame.
Design wise it’s more esoteric than most mainstream amps, utilitarian some might
say. Its straight lines and front panel that overhangs the sides – hinting at the fact
that it can be rack-mounted with an optional kit – mark it out as a serious-looking
receiver aimed at enthusiasts. It’s not exactly pretty then, but its tasteful black
finish means it stops short of eyesore status.
Anthem MRX 300 Connectivity
The rear panel doesn’t quite offer the all-encompassing selection of sockets you
might expect for the money. There are no multichannel audio inputs, and you’ll only
find four HDMI v1.4 inputs, which is fewer than most similarly-priced Japanese
models. The single output won’t please those who want to feed two displays
simultaneously either, but to be honest most users will be more than happy with
what’s on offer.
Elsewhere there are five digital audio inputs (three optical, two coaxial) and two
outputs (one of each type), six sets of analogue stereo inputs and two outputs,
7.1-channel pre-outs and zone 2 output. On the video side you get three sets of
component video inputs and one output, plus three composite video inputs and
three outputs. A 12V trigger, RS-232 and IR sockets have custom installation
covered, while a radio antenna jack and an input for an optional iPod dock complete
the line-up.

Anthem MRX 300 - Features and Operation
Anthem MRX 300 Features
The Anthem MRX 300’s most attractive feature is Anthem Room Correction (ARC),
which calibrates the unit’s performance based on your room’s acoustic properties.
What separates ARC from most other auto setup modes is that it’s not integrated
into the receiver itself but runs separately on a PC.
Bundled in the box alongside the software CD-ROM are a microphone and stand,
which are used to measure the acoustic properties of your listening room. Both the
receiver and microphone have to be connected to USB ports on your PC – in the
receiver’s case you have to use the RS-232 port, but if your PC lacks RS-232 then
you’ll need a serial-to-USB adapter (Anthem provided us with a Keyspan). You also
get a USB cable and extension cable in the box.
Before you get to the measuring bit, you have to set the speaker distances
manually in the unit’s setup menu. You can also set the parameters you want ARC
to measure, giving you a great deal of manual flexibility – including separate
configurations for movies and music – but if you’re a complete novice then it can do
everything for you.
Run the software and the receiver plays test tones from each speaker, which are
picked up by the mic and measured. To make sure the sound is optimised no matter
where you sit, you should take readings from various positions around the room –
the minimum is five and the maximum is 10.
ARC then calculates the correct output levels, crossover frequencies and EQ,
producing a series of graphs for each channel. These show the measured response
(with all the troublesome peaks and dips), the target response and the calculated
response after correction. These results are then uploaded to the receiver, and
because they’re saved on your PC you can upload them again in the future if you
need to.
It might all look a bit nerdy and complicated, but it’s not quite as impenetrable as it
seems – and there’s a good chance you might not have to carry out the procedure
yourself as Anthem recommends that its dealers install the receiver for you where
Enthusiasts will no doubt love it, particularly because of the dramatic impact it can
have on performance – do a before and after comparison and the improvements are
obvious. And on a more basic level, getting all this extra hardware in the box feels
like a real bonus, as it would no doubt cost a bomb to buy it all separately.

With no DLNA, internet radio or USB playback to jazz up the feature list, we’re left
with just the basics. The MRX 300 decodes all the key audio formats, including
Dolby True HD, DTS HD Master Audio, DTS-ES, DTS 96/24 and Dolby Digital EX.
There’s also a range of listening modes, including AnthemLogic Music and Cinema,
Dolby Pro Logic IIz, Virtual Speaker, Dolby Headphone and DTS Neo:6.
The Anthem MRX 300 offers video processing too, including upscaling to 1080p via
HDMI, composite/component-to-HDMI video conversion and passthrough for
1080/24p and 3D signals.
Anthem MRX 300 Operation
The Anthem MRX 300’s onscreen menu system is excellent, using a highly logical
structure, clean fonts and discreet icons to jazz up the look. The main menu is split
into the key areas – video outputs, speaker configuration, audio/video setup and
presets, displays, triggers and general settings.
A Quick Setup mode guides you through basic stuff like the connection type, output
resolution and your speaker arrangement – including whether you have the sixth and
seventh channels on surround back or Pro Logic IIz front height duties.
This user-friendly layout is a godsend because there is loads to tweak, offering
amazing versatility for those with complicated systems. You can store parameters

and listening modes for individual source inputs, as well as make detailed manual
adjustments in the Speaker Configuration menu, including bass management, levels
and distances (although if you’re using ARC you’ll only need to fiddle with the
latter). There are far too many options to discuss here, but rest assured that the
Anthem MRX 300 leaves no stone unturned.
In the box are two remotes – a larger main handset and a smaller one for use in a
second zone. The main remote boasts a thoughtful layout, with clearly separated
menu controls in the middle and labels spelled out in large capital letters. It’s easy
to find frequently used stuff like source switching and volume control, and thanks to
the built-in backlight it’s easy to use in the dark too. The smaller remote pares
things down to the basics, with central menu controls, a cluster of input selection
buttons and clearly marked volume keys.
Anthem MRX 300 - Performance and Verdict
Anthem MRX 300 Performance
It might be lacking in features, but the Anthem MRX 300 makes up for it with
sensational sound quality. There are levels of refinement and raw power at play here
that instantly justify the price tag – particularly with ARC working its magic.
Movie playback is breathtaking. The Anthem handles Super 8’s train crash scene in
an exciting and aggressive manner without losing control as the huge train carriages
start crashing into one another at full pelt.
The sound is immersive thanks to the detailed atmosphere conjured up by the
surround channels, while smooth steering guarantees everything sounds natural
when effects pan from speaker to speaker.
Spot effects are fast and snappy, dialogue is clear and sudden dynamic shifts – like
the moment when a flying metal door crashes to the ground and shatters the
silence – happen in the blink of an eye.
The Anthem MRX 300 also musters immense power despite its modest 80W per
channel rating, which Anthem claims is a more realistic measurement than its rivals
normally quote. There’s plenty of puff to drive larger speakers, but it’s equally
comfortable with compacts like the Paradigm Cinema 100 CT, which proves a match
made in heaven.
It provides a room filling sound without cranking the volume too high, but when
pushed it flat out refuses to distort. Bass is of the highest order too, making every
gunshot or explosion punch right into your gut. ARC deserves a special mention
here. After room correction, the sound is tighter and more focused, with less bass
boom from the subwoofer that stops it overpowering the other speakers.
So the Anthem MRX 300 can be a beast, but there’s beauty here too. Its sound is
open and transparent, twinkling with detail from every speaker. Such is its level of
refinement that it can make you fall in love again with films you’ve seen a hundred
times. It’s that good.
This poised sound works well with music too, a talent that sets the MRX 300 apart
from many of its mainstream rivals. Lianne La Havas’ No Room For Doubt sounds
particularly spine tingling, picking out all the nuance of the voices and the twang of
guitar strings.
Anthem MRX 300 Verdict
The Anthem MRX 300 lacks the extensive connections and features found as
standard on mainstream rivals, eschewing network connectivity, USB ports and web
content to concentrate on the things audiophiles really care about – classy sound
And sure enough it’s a wonderful performer, delivering a potent yet refined sound
with lots of detail and visceral bass – helped along by the nigh-on miraculous
effects of ARC, the superb room correction system. It’s for this reason that Anthem
gets our recommendation despite its lack of eye-catching features.
