Description:
The MX6120 is a member of the long line of Knoll multi-
channel amplifiers. Designed primarily for the custom install industry, it
is used to power speakers with different or similar sources in multiple
rooms. With 6 channels rated at 120 watts per channel at 8 Ω, the
MX6120 packs some serious punch. Each channel has a gain control.
The MX6120 can be turned on and off via the front panel power switch
or via the 12 VDC trigger. 1-3 MX6120 stereo channels can be
connected to a line level BUS input. MX6120 amplifiers designed to
meet the amplifier needs of custom installed systems where high-
quality sound is a specific requirement.
Key Features:
1. Size efficiency.
The MX6120 consists of a total of 6 high
power amplifiers in one 3-1/2” high enclosure. Each power
amplifier channel can deliver 120 watts RMS into an 8-Ω load.
2. Automatic protection circuitry.
Each MX6120 channel is
individually and fully protected against low impedance,
overheating, overloading, over voltage and under voltage. The
protection circuitry automatically restores the amplifier channel
as soon as its parameter returns to the safe operating area.
3. Individual input gain adjustment.
Each channel features
an input gain adjustment pot to adjust each channel for gain
and speaker sensitivity variations.
4. External power on/off.
The MX6120 can be turned off and
on by external controllers via its 12 VDC trigger jack.
5. Stackable 17" chassis.
19” rack ears available.
6. Bus Feature.
Certain installations require that some or all of
the stereo channels play the same content. Instead of using Y
cords, the Knoll "BUS" connects any or all of channels 1-3 to the
stereo BUS inputs.
