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. Of course this
is needed so you can monitor at a different level to what you send to your recording device!

If you choose to use your own make-up gain stage rather than the PM8’s in24 dB make-up
gain stage, simply use the ‘Passive Output’ pair instead of the ‘Master 1’ output pair. You would then
connect to your preferred 2-Channel microphone preamplifier of choice to compensate for dB level
loss during the attenuation and summing process prior to connection to your 2-track final recording
device of choice (DAT, 2-track analog master recorder, etc).

To complete your mix-down simply set your PM8’s channel level controls to achieve the desired
channel level balance required, and attenuate the ‘Master 1’ level attenuator to an acceptable level
for your desired 2-track recording device to accept.

By mixing this way through the PM8 you will have minimized some of the digital summing effects
of your Cubase workstation. Like many other audio professionals before you, we believe you too
will be astonished once you hear the difference!

* Power is only required to operate the ‘Master 1’ or ‘Master 2’ output pairs internal ‘make up’ gain
electronics. If passive operation is preferred and you would like to use your own ‘make up’ gain
device, you should use the ‘Passive Output’ pair that does not require mains power connection.
