The Most Musical Sound
The M-CR612 is a compact network CD receiver with a high-output class D amplifier and full digital processing on digital sources. It plays CDs, streams over the network, and accepts TV or other digital audio via optical inputs.
Digital Audio Amplifier
Rated output is 50 W + 50 W into 6 Ω (1 kHz, THD+N 0.7 %), with dynamic power of 60 W + 60 W (6 Ω, 1 kHz, THD+N 10 %). Speaker terminals accept 4-16 Ω loads. Speaker A/B, bi-amp and parallel BTL configurations are supported. A headphone output with a three-level gain selector is provided.
Wireless Streaming and HEOS
HEOS Built-in enables multi-room playback with other HEOS devices on the same network. AirPlay 2, Bluetooth and dual-band Wi-Fi (IEEE 802.11a/b/g/n) are included. A Bluetooth OFF mode is available when the lowest noise floor is preferred.
Voice Control and TV Integration
Voice control is supported via Amazon Alexa, Google Assistant and Apple Siri (no built-in microphone). Two optical digital inputs connect a TV or other digital source; the unit can learn a TV remote's IR codes for volume, mute and source selection.
