Mint Condition with 6 Month Alto Music Warranty!

There are nine audio blocks that make up the 8MX2: Eight Input / Output / Return Channels and a Master section.

Channel front panel switches include Cue, Phase, Reverse, 48V Phantom Power, Channel/Return signal select for Mix level & pan and Mix assignment. There are two dual concentric controls. Input gain (Inner) with Limiter Threshold (Outer) and Mix Level (Inner) with Mix Pan (Outer).

Master Section front panel switches include Mix Output / Mix 2 Trk Return to Phones (monitor), Channel Return to Phones (monitor), Channel pre / post VCA signal select to Phones (monitor) Mix Pan (outer), and a single shaft control which controls Phones (monitor) level. A phones jack is provided on the front panel. There are two 10 segment meters for Level and Gain Reduction metering.

On the rear panel each channel section has individual Ground Lift switches. Two 9 pin D connectors are provided for inter unit linking and two 25 pin D connectors carry the channel outputs and channel return signals. Mix, Mix 2Trk return and Monitor signals are all TRS jacks. All inputs and outputs are fully balanced.

Signal Flow

The proprietary JDK microphone peamplifier will accept signal levels from 0dB to minus 65dB. This preamplifier has 48+ve and 48 minus ve power rails and produces very low THD even at high input levels or gain. The 8MX2 is pin 2 hot. Following the main gain stage there is a phase reverse switch. The output of the Mic preamp passes through a VCA used for hard wall limiting and feeds the 25 pin D machine send multipin connector on the rear panel. The input gain control and switch when depressed allows the monitoring of all signals in the channel and the return paths. Machine return 25 pin D connector signals feed balanced line input amplifiers on each channel. Signal feed to the Mix Level assign switch places this signal onto the Mix buss. Channels have individual XLR Ground lift, and Phantom Power switches.

The Master section of the 8MX2 allows the monitoring of the cue signals either PRE / POST VCA or channel return. When a channel is cued the Limiter gain reduction is shown on a 10 segment display whilst the selected signal level is displayed on a second 10 segment tri-color display. The signal can be monitored via headphones or the monitor outputs on the rear panel.

Mix master level and balance is a dual concentric control with the Mix Left and Right outputs on the rear panel. Left and Right inputs are made available for 2 Trk (MIX) Returns and can feed the monitor signal path. A mono sum of Left and Right MIX signals is displayed on the level meter when no cue is selected. A seperate monitor level control is provided.
