We use voltage levels that are very common to analog synthesizers which will make it easy to interface with other audio equipment.
Pitch Control Voltages: 1 volt per octave
Each synthesizer module consists of a front panel and a circuit board mounted on the back. Panels can be individually removed from the synthesizer cabinet after removing the power connector.
Panels are made of .062" aluminum, sanded, formed on the sides for strength, masked, painted, textured, then silkscreen printed. All panels are 8.75" in height and come in various 'widths'.
Common Panel Widths
Panel graphics are silkscreen printed using white enamel ink.
We use linear power supplies to reduce noise. They're heavier and more expensive than switching power supplies. These supplies deliver +15V, -15V, and +5V for use by the modules in your system. A power supply has 2 cables: 1 for the AC power input which connects to a Q102 or Q137 power module, and 1 for the DC power output which connects to the cabinet's wiring harness. Nylon connectors are used on the cables - see below.

Signals - 1/4" Phone Jacks
Our modules use standard 1/4" jacks and plugs for all waveform and control voltage routing. These are much easier to handle and more durable than 3.5mm connectors, and offer a sheilded ground unlike banana connectors. 1/4" jacks and plugs are also used on most other audio equipment allowing easy interfacing.
Use the Q120 Connector Interface Module to interface system signals to RCA connectors, 3.5mm connectors, and banana connectors. Also see the Q121 Banana Jack Interface Module, and the Q122 Mini-Jack Interface Module.
External DC Power - 6 pin Circular DIN
We use these strictly to supply DC power to the external world, or between cabinets. See the Q103 DC Power Interface Module and the QIC Inter-Cabinet cables for details. These type of connectors are made by a variety of manufacturers.
3 = +5V
4 = Ground
5 = -15V
6 = No Connect
AC Power - IEC 320
We use standard IEC connectors for the AC power. This allows use of your synthesizer in almost any country with the correct power cord.
These connectors are inside the system, so the operator will never see them.
Internal DC Module Power - 6 pin MTA
We use these connectors strictly for DC power supply connections.
Modules have the male PCB mount version, and the cabinet's cable harness has the female version.
Female 24AWG cable mount: AMP #6404416
2 = KEY - pin missing and plugged
3 = +5v (Red)
4 = gnd (Black)
5 = -15v (Green)
2 pin MTA Connectors for Panel Components
Female cable mount: AMP #6404412
2 = Ground (ring)
Internal Pot/Switch - 3 pin MTA
We use these for potentiomenters, switches and other devices requiring 3 pins. DPDT switches will use 2 of these.
Female cable mount: AMP #6404413
2 = Wiper
3 = CW Side
DC Harness - 4 pin .093 Nylon
We use these strictly for connection between the power supply and the DC Cable Harness to carry the DC voltages. The cable harness has the male and the power supply has the female. For safety and simplicity we don't use this type of connector anywhere else.
Female cable mount housing: AMP #7700751
2 = +5v (Red)
3 = Gnd (Black)
4 = -15v (Green)
AC Switch - 2 pin .093 Nylon
We use these strictly for connection between the AC power switch on the Q101 AC Power Control Module, and the Q102 AC Power Interface Module to carry high voltage AC. For safety and simplicity we don't use this type of connector anywhere else.
Female cable mount housing: AMP #7700651
Power Supply AC - 6 pin .093 Nylon
We use these strictly for connection between the power supply and the Q102 AC Power Interface Module or the Q137 Power Control & Interface Module to carry high voltage AC. For safety and simplicity we don't use this type of connector anywhere else.
Female cable mount housing: AMP #7700861
