The M80 is an Eight-Channel Microphone/Instrument Preamp featuring low noise, balanced input transformers, ultra low impedance mix bus and vintage warmth control.
The M80 is designed with a low impedance stereo mix bus for assigning and panning any channel to the main stereo output connectors. It also has a high gain headphone output for monitoring the main bus.
A special feature of the M80 is the IDSS control on each channel. The IDSS control adjusts the drain current on the input FET amplifier thus altering the even harmonic levels of the signal. A wide range of control is offered from 0% to 100%. This feature may be used to adjust the harmonics of the signal from absolutely pure (no harmonics) to simulation of the effects of tape saturation and tube “warmth”.
The back panel of the M80 is fully loaded with XLR balanced input/output connectors and TRS line inputs via Neutrik combo connectors. Each channel is equipped with separate send and return jacks for inserting dynamics processors (such as the Presonus ACP88). Mix output connectors are XLR for balanced signals as well as for line level signals such as digital audio card inputs.
The M80 is housed in a double rack space, steel chassis with a high quality blue anodized front panel. The unit also has an high output headphone amplifier and utilizes an external power supply to create a noise free preamp environment (S/N >98dB!).
