Modular Sound Mixer

Output Module

The output module contains all the electronics required for the various mix and output stages along with the monitoring and VU meter sections. This is a very versatile module which gives total control of all the facilities available and it can be placed in any position in the mixer to suit the individual user. Most of the connections are on the rear of the unit.

Monitoring: Visual monitoring is provided by a stereo 24 segment led bar graph meter. Extensive monitoring options are provided via a monitor balanced control and split cue switch. Two powerful stereo headphone amplifiers are incorporated which are designed to drive headphones of 32 ohms or greater. The main phones output is situated on the top right hand of the front panel. A second output on the rear panel can be configured to provide for a second operator to have independent monitoring facilities via the AUX2 buss.

Illumination: A 12 volt socket is provided to fit a lamp for working illumination.

A.V.O. (Automatic Voice Over): When activated any microphone signal present will dim the music signals to allow talk over. The amount the music is dimmed is determined by the attenuation control. The adjacent sensitivity control sets the triggering level of the AVO SYSTEM.

AUX RET (Auxiliary Return): A basic stereo input configured to accept balanced or unbalanced input signals via 2 x 1/4" 3 pole jack sockets.

Master: Sets the output level of the main balanced output available via 3 pole XLR connectors on the rear panel.

Mono: Allows the master output to be opreated in mono mode.

Zone: Almost identical to the main output except that the signal is not available to the monitoring section and no insert sockets are provided. The output may also be used in mono or stereo as set by a rear mounted push switch located between the XLR sockets.

AUX 1 Master: Adjusts the output level of the signals derived from the Aux 1 sends on the input modules.

AUX 2 Master: Adjusts the output level of the signals derived from the Aux 2 sends on the input modules

AUX 2 Options: An illuminated push button switch (PROG TO AUX 2) routes the programme mix to the AUX 2 output. This provides yet another zone output should this be required.

Booth: Adjusts the level of the booth input which is a mix of music channels only.

Cue to booth: Routes the main phones signal to the booth output so that all the phones monitoring facilites become available on the booth outputs.

Crossfade: a 45mm crossfader controlling studio quality V.C.A.s (voltage controlled amplifiers) to improve crossfader life and ensure good attenuation at the ends of travel. All stereo inputs are fully assignable to the crossfade function.

Contour: Allows the operator to adjust the crossfader characteristics to suit personal taste, from a gentle fade between A and B to a more aggressive fade towards the end of the fader.

Punch: A momentary action push button is fitted to provide rapid switching effects.

Inserts: Sockets are provided for the connection of external signal processing equipment.

Record: 2 pairs of gold plated phono sockets are provided. One pair provides the complete programme mix; the other pair provides the mix of music sources only.

Sub Bass: Provides a mono output for driving a sub bass loudspeaker system. Allows frequencies below 70Hz to pass through. An internal jumper allows higher bass output if required.

Lighting Trigger: A mono fully floating transformer isolated trigger output provides safe connection to lighting equipment.

Priority: A priority input with adjacent level trim control and triggering socket are provided to help comply with fire regulations. Internal jumpers provide the option to mute all signals or leave mic signals active and introduce the priority signal.
