1. INTRODUCTION In purchasing the new PM8, you have acquired a multi-channel passive summing mixer of high class that meets the demands of the home and professional studio. This sturdy 2RU allows for up to 8 channels of audio to be passively mixed down to a stereo output pair. Each input channel features its own pan, mute, and rotary volume attenuator control. Eight professional combo connector inputs (XLR & ¼” TS) and three balanced XLR stereo output pairs can be found on the rear panel.
PM8 front panel 3.3 Mains Voltage & front panel power switch Mains Voltage Important - Before you connect your PM8 to the mains power supply, please make sure that your local voltage matches the voltage required by the unit! The PM8 has a professional internal power supply suitable for operation between AC 110/115v – AC 220/230/240v. A voltage configuration switch on the left hand side of the rear panel should be set to match the appropriate voltage of your mains power supply.

FRONT PANEL CONTROLS & INDICATORS 4.1 Independent (8x) rotary volume attenuation controls 8 x rotary volume attenuator knobs are provided for independent volume attenuation of the corresponding channel input signal. They allow precise level adjustments within 1dB from 0 to -40dB. 4.2 Independent (8x) led enabled mute switches 8 x led enabled mute switches are provided for independent channel muting of the corresponding channel input signal.
internal +24dB make-up gain stage to compensate for the dB loss during the attenuation and summing process. - Passive Output - As all make-up gain devices do have their own unique sound characteristic, the PM8 also features a ‘Passive Output’ pair for those users wishing to make their own make-up gain device selection instead of ours. Users can choose their preamplifier of choice to make any necessary dB compensation adjustment prior to connection to their destination device.
The ‘Master 1’ output pair could be connected to your choice of 2-channel mix-down recording device whilst the ‘Master 2’ output pair could be connected to your monitoring solution of choice. * The individual master level attenuator controls on the front panel allow for independent levels to be sent to both your 2-track master recording device and your monitoring solution.
