Expand Concept

The SSM Expand 8 HP module provides extended functionality of the SSM.

Gate/Trig: Gate (Green LED lit) provides 10V outputs for each routing button. It mirrors the routing shown by the SSM LEDs. Trig mode (Red LED lit) will output a trigger when a step (CV, Step/Gate or Reset) is taken. Pushing a routing button will not change the output thus providing synchronized triggers.

Trigger Length: CV and knob provide adjustable trigger length.

Retrig on Step: When on, gates and triggers will retrigger quickly when a step is taken.

Invert Behavior: When on, routings that are OFF will produce ON triggers or Gates.

DAC3/4: Two 4 bit DAC outputs that output a weighted 4 bit voltage between 0 and 5 volts. From routing columns 3 and 4.

Step: Outputs a trigger for each step, reset or CV change that is made to the SSM.

Installation: Connect the 20 pin ribbon cable to the GTExp header on the SSM, and the ToSSM connector on the Expand. Red Stripe Down.

Specs & Notes

Width: SSM 16 HP. Expand 8 HP.

Current consumption: SSM +80mA/-32mA. Expand +40ma/-3mA.

Voltage Levels: Input range +-10V. Output range +-10V. Step/Gate and Reset sense signals at 0.8V.

Operating Frequency: Maximum transition frequency is 26kHz. Pushing buttons at high clock speeds will slow the response as the buttons are debounced.

Compare Input: +-10V. Normaled to 0.5V.

Depth: SSM & Expand - 25mm with connectors

Compliance: The SSM and Expand are RoHS and CE compliant.

Warranty: The SSM and Expand are covered under warranty for 12 months after purchase. Please contact us if you ever have problems. We will take care of you.
