AD Input Section
A
INPUT A & B (BAL) connectors
AD Inputs 1 through 24 feature balanced XLR-3-31-type connectors and balanced 1/4-inch
phone jacks, both with a nominal input range of –60 dB to +10 dB. Phantom powering
(+48 V) is supplied to the XLR-type connectors, with individual ON/OFF switches on each
input. The phone jacks, which can also be used with unbalanced phone plugs, have priority
over the XLR-type connectors, so when a phone plug is inserted, the XLR-type connector
is disconnected. These inputs can be patched individually to the Input Channels or Insert
Ins. With their high sensitivity and PAD switches, these inputs can handle a wide range of
signals, from condenser microphones to “hot” line levels. See “AD Input Section” on page
48 for more information.
B INSERT IN & OUT +4dB (BAL) connectors
These balanced 1/4-inch TRS phone jacks are used to insert
external signal processors, etc., into AD Inputs 1 through
24. They are wired: sleeve–ground, ring–cold, tip–hot. The
nominal signal level of both jacks is +4 dB. Inserts can be
turned on and off individually by using the INSERT
ON/OFF switches. See “AD Input Section” on page 48 for
more information.

STUDIO MONITOR OUT +4 dB (BAL)
These balanced 1/4-inch TRS phone jacks, nominal output
level +4 dB, output the analog Studio Monitor signal for
monitoring in the actual studio. The source, which is
selected by using the STUDIO buttons in the MONITOR
section, can be Aux Send #11, Aux Send #12, the Stereo Out, or Control Room. The output
level is controlled by the STUDIO LEVEL control. See “Studio Monitoring” on page 133 for
more information.
