Inserting available on every channel. Allows external devices to be inserted between the preamp and the A-D converter, using the 25-pin D-type cable. Selectable per channel; choose one of four carefully selected input impedances, including the original ISA110 setting, to suit any microphones.
High pass filter, polarity reverse and phantom power. Each has a dedicated switch, independent on each channel. Eight Lundahl LL1538 mic input transformers. The original mic transformer used in the original Red modules helps to provide the unique sound and performance of this groundbreaking design. 0 dB to 60 dB in 10 dB steps.126 dB measured at 60 dB of gain with 150 Ohm terminating impedance and 22 Hz / 22 kHz bandpass filter.
