Our take on the Marantz M-CR603

by Marshall Chase
Marantz

The sound solution for the less-is-more movement

On one hand, you want something that sounds much better than an iPod® or Bluetooth® speaker. On the other hand, you want something less complex than a surround sound system. You'll find your sweet spot in a stereo receiver. In addition to being easy to set up and use, many now offer Internet radio and other network music options. Add your music source and two speakers, and you're ready to relax and enjoy your tunes. You might even connect your TV for improved sound with movies and shows.

You keep your music everywhere. You've got CDs in the truck and a flash drive for the office. Let's not forget the iPod® you take running, and probably every place else. At the end of the day, wouldn't it be great to have one place to bring it all together? That's where the Marantz M-CR603 comes in.

Built to play all your music — beautifully
Gather your CD collection — the discs you bought and the discs you burned. Dig your thumb drive out from your coat pocket. Pull your portable player out of your gym bag. The 'CR603 can take almost any source of music you can dish out. You can plug your iPod® straight into the receiver's front panel — no dock needed. This connection bypasses your iPod's audio circuitry, using the receiver's built-in high-quality digital-to-analog converter. That means your favorite tunes will take on new life. Plus, you can upgrade this receiver to add Apple AirPlay® for ultra-convenient access to your iTunes® library. And with outputs for two sets of speakers, you can add a second pair, or bi-amp a single pair of bi-ampable speakers for sound with a little more oomph.

Music from home — and abroad
Did you hear that click when you plugged a network cable into the M-CR603's Ethernet port? That's the sound of your musical world opening wide. This DLNA-certified receiver not only plays music files from your computer, but its DAC will have them sounding great. And with high-speed Internet, you'll also have global selections from online radio stations, and easy streaming from a variety of music services, including Rhapsody®, Pandora® and Napster® (subscriptions may be required.)

Unleash your iTunes® music — free upgrade to AirPlay®
Apple's exciting AirPlay technology lets you access your favorite music from your iPhone®, iPad™, iPod touch®, or your iTunes library on your computer using this Marantz receiver. You'll be able to control iTunes and see music information, including your album art, track titles, and artist info on your compatible Apple device, or on your TV if your Marantz receiver is equipped with a video output. First you will need a free firmware upgrade. Go to the Marantz website for instructions on how to download and activate the upgrade. Requires a wireless home network. Receiver requires wired connection to the router.

4-Channel Digital Amplifier: The Marantz M-CR603 features an ultra-efficient 4-channel discrete digital amplifier. The digital amplifier produces little heat so it provides a stable, cool environment for exceptional long-term reliability. The amplifier is rated at 40 watts x 2-channel at 1kHz, in 8-ohms, with 0.7% THD (50 watts x 2-channel at 1kHz, in 6-ohms, with 0.7% THD).

A & B Speakers: Speaker A and B mode allows for two pair of loudspeakers in different rooms with the same source playing in both. With the output of Speaker A fixed, the audio level of Speaker B can be adjusted within the range of -6 dB to +6 dB.

Stereo Bi-Amp Operation: A bi-amp connection is possible with speakers that have two set of inputs by combining the receiver's A & B speaker connections. This allows you to drive the treble and bass drivers of a speaker with separate amplifier channels, which enables better sound quality.

Analog Inputs/Outputs: The Marantz M-CR603 features three analog audio stereo inputs and one analog audio stereo output. There are two stereo RCA inputs on the rear-panel and one stereo minijack (3.5mm) input  on the front-panel. There is also a stereo RCA output on the back panel of the unit.

Digital Input: The Marantz M-CR603 is equipped with one optical digital input for connecting a digital audio source, such as your satellite/cable box, TV, DVD, or Blu-ray player.

Speaker Terminals: High quality binding-post screw terminals provide secure connection to your choice of loudspeaker cable. The unit's binding-post screw terminals will accept banana plugs (single/dual), pin-connectors, and bare wire. The collar surrounding the binding post terminals prevent the use of spade connectors.

Note: The M-CR603 will support speakers with impedances from 6 to 8 ohms.

Subwoofer Output: The Marantz M-CR603 features a  mono subwoofer preamp output for connecting a powered subwoofer.

Headphone Output: The M-CR603 features a front-panel 3.5mm headphone output. Once a set of headphones is connected, the receiver's connected speakers (A/B) are muted.

Tone Adjustments: The Marantz M-CR603 offers Bass, Treble, Balance, Bass Boost, and S.Direct sound adjustments.

  • Bass & Treble: Independent Bass & Treble adjustments (+/-10dB) to emphasize low and high frequencies.
  • Balance: Adjust the left & right volume balance (L6/R6).
  • Dynamic Bass Boost (DBB): Emphasize the system's bass sound (On/Off).
  • Source Direct (S.Direct): High-quality audio playback without passing the audio signal through the unit's sound quality adjustment circuits.

Speaker Setup: The receiver's Speaker Setup menu lets you match your speakers and their location to the Marantz integrated CD/network receiver. Five types of settings can be selected. A different setting can be selected for Speaker A & B.

  • Response 1: Cuts low frequencies of 60 Hz or under by -12dB/oct.
  • Response 2: Cuts low frequencies of 100 Hz or under by -12dB/oct.
  • Response 3: Cuts low frequencies of 60 Hz or under by -12dB/oct. Also, raises the 400 Hz region by 3 dB.
  • Response 4: Cuts low frequencies of 100 Hz or under by -12dB/oct. Also, raises the 400 Hz region by 3 dB.
  • Flat: The crossover is set to flat. This enhances bass frequencies when speakers are placed directly on furniture or on a rack.

Protection Circuit: The unit's protection circuit is activated in the following situations:

  • If the speaker cable wire touches the rear panel or screws, or if the speaker cable's positive and negatives leads are touching.
  • If the surrounding temperature is extremely high.
  • If the inside of the amplifier gets hot due to extended use at a high volume levels.

AM/FM Tuner

Built-in AM/FM Tuner: The Marantz M-CR603 is equipped with a built-in AM/FM tuner with excellent sensitivity to pull in those weaker signals.

Preset Tuning: You can store up to 99 of your favorite AM/FM radio stations. You can do this manually, or have the integrated receiver do it automatically for you.

Station Names: You can give each preset station (up to 99) an 8-character name, so it can be easily indentified.

Perfect compact design and sound

Written By tl rupp, Bend, OR on Thursday, October 03, 2013
Crutchfield Customer Review (What's this?)
 
I bought this unit because of it's reputation as a brand and because of the size I needed for the space that I had available. The features that it came with were also a bonus. I am running a pair of in wall speakers in the kitchen, and a pair of outdoor speakers for our patio. When running just one pair it sounds great. However, when running both, you can tell that it bogs down a little, but even at that level it still performs and sounds great. Works perfect for my application.

Great Little Multi-Function Unit

Written By Hal E, New York on Sunday, October 09, 2011
Crutchfield Customer Review (What's this?)
 
Small, well designed, visually appealing unlike most big black box receivers. Looks good on display and greatly improved sound of old technology speakers even running four at a time. Built-in CD players also a great feature; no need for separate unit. Convenient front USB port for iPod or music stored on USB drive. When connected to my router via Ethernet cable, I was able to access Internet radio and music services--Napster, Pandora, Rhapsody--and could also play all music stored in iTunes on my computer. Only drawback--like most of these new audio and vidio receivers, it took much time and patience to set up. This unit was no exception. Surely is not "plug & play." But great once it works.
