The 16hp A-138p and A-138o modules are a simple performance mixer designed to at least partially replace existing external mixers by providing the most important functions in modular form. A-138p is the 4-fold input module, A-138o the output module. One or more A-138p can be combined with an A-138o. A-138p Features: 4 channels Controls, displays and inputs per channel: Input (3.5mm mono jack) Signal LED (as a rough indication of the input level, the measurement is made according to the gain control) Mute switch Gain control (to adjust different levels of different signals) Level control (the actual volume control for the input, linear characteristic) Panorama control (distribution of the signal on the left and right outputs of the A-138o) Aux control (auxiliary path, for example for pre-listening to a signal or as an effect way usable) Internal jumper to set whether the aux control picks up the signal before or after the level control (pre / post). Internal 5-pin connection to connect the module to the A-138o and, if needed, to another A-138p The A-138p requires an A-138o to operate. Alone, the module A-138p can not be used.` Product Specs Item Number: 20746 Make: Doepfer Model: A-138pv Condition: Brand New Finish: Black Categories: keyboards-and-synths ⇒ eurorack Function: Mixer Made In: Germany MPN: A-138pv EAN: 4250711113902 Modular Grid: Eurorack ⓘ + Dimensions*: 16 HP 40 mm deep Power*: Module does not draw current * User contributed details
