-12v. This stripe needs to line up with the -12v pins on the power rail and the -12v pins on the module. Failure to match up the pins correctly can result in damage to one or all the modules in the Patch Box. On the power rail, the -12v pins are clearly labeled. On the individual modules, the positive and negative sides of the pin connectors are labeled next to the power header on either the top or bottom of the PCB. -

SWITCH 2 - Patchable footswitch can be used as on/off or A/B switch. BYPASS - True bypass circuit enables or disables the entire Patch Box. GAIN Knob - Controls the gain of the 1/4” input jack. Signal begins to overdrive after 12 o’clock. -
Page 6: Rear Panel Controls
Rear Panel Controls INPUT Jack - 1/4” unbalanced instrument input. OUTPUT Jack - 1/4” unbalanced guitar or line level output. 15V DC Power Jack - 2.1mm barrel connector for external 15v DC 2.6 to 5A adapter. EXP 1 Jack - Balanced 1/4” input for universal expression pedal such as the Moog EP-3 or M-Audio EX-P expression pedals. -

The Patch Box signal path is divided into two types of signals: audio signals and control voltages. The audio signal is the sound that is produced. The audio signal path starts at a sound source. -
Page 8: Installing Modules
1. Unplug the power adapter from the back of the case. 2. Flip over the case and carefully remove the bottom of the Patch Box by first unscrewing the 4 feet and 2 additional screws on the bottom of the Patch Box. -

Patch Box. Use the patches provided as a teaching tool. Once you have set up a patch, adjust knobs and remove cables from the Patch Box while referencing the module description pages within the manual. -

The default Patch Box patch does not require any modules. Plug a guitar or other instrument into the 1/4” input on the rear of the Patch Box enclosure. This will turn on the unit. Next, plug the output of the Patch Box into an amplifier, mixer, or audio interface. - Page 11 INPUTS into the input jack of a Filter module. The output of the Filter module is then patched into the OUT jack of the Patch Box. The signal then passes through the OUTPUT level knob into the 1/4” output on the rear of the enclosure.
- Page 12 Utilizing an Expression Pedal The expression inputs on the rear of the Patch Box are used for controlling the parameters of installed modules during a performance. The Expression inputs create a 0-5v signal that can be patched into a CV input of any installed module.
- Page 13 LFO (low frequency oscillator) patched in the Frequency CV input instead of the envelope follower. An envelope follower, we are using the Pittsburgh Modular Detect module in this example, outputs a control voltage that is based on the signal level of the incoming audio signal.
- Page 14 This patch adds a second effects module and a split expression pedal control signal to the basic “Patching a Module” patch. The multiple section of the Patch Box patch panel is used to split a signal in two. This patch uses the multiple to allow an expression pedal to control two parameters at the same time.
- Page 15 Just like the previous example, second effects module is patched between the output of the Filter and the OUT jack of the Patch Box. An LFO triangle waveform output is patched into the Multiple. A second patch cable is patched from the Multiple into the Frequency CV input of the Filter.
- Page 16 Footswitch as On/Off Switch Starting again with the basic “Patching a Module” patch we are going to add a footswitch controlled modulation source. The footswitch will be used to turn the modulation on and off. Both switches are patched in exactly the same way. The jacks are arranged in a simple double pole layout.
- Page 17 Footswitch as A/B Switch Starting with a simple patch that uses the Crush down-sampler module, we are going to add a footswitch to flip between two different modulation sources. The footswitches can be used to switch between two audio or control voltage sources by patching the audio or control voltage sources into the left and right jacks.
- Page 18 (right jack) of Switch 1. The off position (left jack) of Switch 1 is patched to the Patch Box input. The output of Switch 1 (center jack) is sent to a multiple so the signal can be split and patched into both the Filter input and the Switch 2 off position (left jack). The output of the Filter is patched to the on position (right jack) of Switch 2.
