API Select TranZformer CMP Manuals

The API Select TranZformer® CMP provides unsurpassed sonic sculpting by incorporating key elements of a legendary API 527 VCA-type compressor circuit into a versatile and robust guitar effects pedal. Features include a buffered bypass in/out footswitch, adjustable attack and release times, wet/dry blend control, selectable “feedback” and “feedforward” compressor styles, transformer output, and of course the classic API sound. SIGNAL FLOW (from right to left): Input > Sustain > Blend > Transformer Output AUDIO CONTROLS 1. INPUT: Input level; +9dB to +30dB; More gain creates more compression 2. SUSTAIN (compression): Determines amount of compression (gain-reduction); Higher levels provide more compression (lower threshold) 3. BLEND: Mixes the dry (uncompressed) signal with the wet (compressed) signal. 4. OUTPUT: -inf. to 0dB output level control; 0db (no cut) is fully clockwise SWITCHES A. ATTACK: Sets the compressor’s attack time to either FAST (1ms) or SLOW (10ms) B. RELEASE: Sets the compressor’s release time to either FAST (300ms) or SLOW (1s) C. TYPE: Selects between feedback (OLD) or feedforward (NEW) compression styles D. BYPASS: Buffered bypass footswitch E.
