1. Power Input : While Seventy-Two is powered off, connect the included power cable to this
input and then to a power outlet.
2. Power Switch : Use this switch to power Seventy-Two on or off. Power on Seventy-Two only
after you have connected all of your input devices and before you power on your amplifiers and
loudspeakers. Power off your amplifiers and loudspeakers before powering off Seventy-Two.
3. Main Out (XLR): Connect these outputs to loudspeakers or an amplifier system. Use the
Master knob on the top panel to control the volume level.
4. Booth Out (1/4”/6.35 mm, TRS): Connect these outputs to booth monitors or a booth amplifier
system. Use the Booth knob on the top panel to control the volume level.
5. Session In (RCA): Connect these inputs from a line-level device like another mixer, a CD
player, drum machine, etc. The signal will be sent directly to the program mix. Turn the Session
In knob on the top panel to control the input volume level.
6. Session Out (RCA): Connect these outputs to another mixer, recording device, etc. The
program mix will be sent to these outputs. Turn the Session Out knob on the top panel to
control the volume level.
7. Deck PH / CD In (RCA): Connect these inputs to an external audio source or to a turntable, CD
player, or other line-level device. Remember to set the corresponding PH / CD selector to the
appropriate position and to set the deck source knob for that deck to PH / CD to play its audio
signal on that deck.
8. PH / CD Selector : Set this switch to the appropriate position, depending on the device connected
to the PH / CD Ins of the corresponding deck. If you are using phono-level turntables, set this
switch to PH to provide the additional amplification needed for phono-level signals. If you are
using a line-level device, such as a line-level turntable, CD player or sampler, set this switch to
CD .
9. Phono Grounds : If you are using phono-level turntables with a grounding wire, connect the
grounding wire to these terminals. If you experience a low “hum” or “buzz”, this could mean
that your turntables are not grounded.
Note : Some turntables have a grounding wire built into the RCA connection and, therefore,
nothing needs to be connected to the grounding terminal.
