Congratulations and thank you for choosing the Knöll MR1250v power
amplifier. The MR1250v is designed to meet the amplifier needs of
custom installed multi-zone systems where high quality sound is a
specific requirement.
Key Features:
1. Individual mute, volume, bass, treble and balance adjustment.
Each of the six stereo channels feature adjustments for bass, treble and
balance. Individual room keypads control volume and mute. Any
keypad or RB8 remote can turn the system off.
2. Cost and size efficiency. The MR1250v consists of a total of 6
stereo power amplifiers with individual volume control electronics in one
3-1/2" high enclosure. Each power amplifier channel can deliver 50
watts RMS.
3. Automatic protection circuitry. Each MR1250v channel is
individually and fully protected against low impedance, overheating,
overloading, overvoltage and undervoltage. The protection circuitry
automatically restores the amplifier channel as soon as its parameter
returns to the safe operating area.
4. External trigger out. An 12VDC trigger output is provided to turn
other components on or off.
5. Stackable 17" chassis. The MR1250v can be stacked or placed in
a 19" EIA equipment rack (requires RM1250 kit).
6. Link Feature. Certain installations require that some or all of the
stereo channels play the same source. Instead of Y cords, "link"
cascades any or all of channels 2-6 to channel 1 (left and right).
7. Data cascade. For larger systems, multiple MR1250v's can operate
in tandem so all MR1250v's turn off and on together and share infrared
signals.
8. Optional fan version. For installations that require a lot of "heavy"
use we recommend the MR1250vf with an internal fan. Some speakers
that claim to be 4 ohms will cause the MR1250v protection system to
activate after mild usage. A fan will help to avoid early protection
system distortion.
