MX855 Amplifier

8 Channel Amplifier

Installation Instructions v7.3

Warning: To be installed and/or used in accordance with appropriate electrical codes and regulations.

Description: The MX855 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 8 channels rated at 55 watts per channels at 8 Ω, the MX855 packs some serious punch. Each channel has a gain control. The MX855 can be turned on and off via the front panel power switch or via the 12 VDC trigger. MX855 channels 2-4 can be linked to channel 1 individually using the link switches. MX855 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 MX855 consists of a total of 8 power amplifiers in one 3-1/2” high enclosure. Each power amplifier channel can deliver 55 watts RMS into an 8-Ω load.

2.Automatic protection circuitry. Each MX855 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 MX855 can be turned off and on by external controllers via its 12 VDC trigger jack.

5.Stackable 17" chassis. 19” rack ears available.

6.Link Feature. Certain installations require that some or all of the stereo channels play the same content. Instead of using Y cords, the Knoll "link" cascades any or all of channels 2-4 to channel 1 (L/R).

7.Bridgeable. Channel 4 can be bridged giving 180 watts RMS into an 8 Ω load for use with subwoofers and speakers that need more power.
