Phantom Powering 41 Phantom Powering CH 1-6 Input channels 1 through 12 feature +48 V phantom powering for use with ON OFF condenser-type microphones. Phantom powering is supplied to the bal- anced XLR-3-31-type connector, and can be switched for inputs 1 through 6 and inputs 7 through 12. Phantom powering should be turned on only when CH 7-12 a condenser-type microphone is connected. ON OFF Warning: Make sure that phantom powering is turned off when connecting an unbalanced source to an XLR input. Pad Switches Input channels 1 through 12 feature 26 dB pad switches. Input pads attenu26dB ate the input signal by 26 dB, allowing the input preamp to work with high-level signals. You may need to use a pad with "hot" signals from bass or snare drum microphones, or "hot" line-level signals. PAD switch settings are not stored in scene memories. Setting Input Channel Gain GAIN controls adjust the gain of the input channel preamps. They're used to optimize the input signal level for the best signal-to-noise performance, and should be set in conjunction with the level meters on the HOME pages. Ideally, the GAIN control should be set so that the signal level is relatively high, and it's okay for it to reach CLIP occasionally. If CLIP is reached often, however, back off the GAIN control a little, otherwise, signal distortion may occur. The GAIN control should be set with care. If it's set too low, the signal-to-noise performance will suffer. If it's set too high, unpleasant signal clipping and distortion may occur. -16 -60 +10 GAIN -34 The GAIN controls on input channels 1 through 12 are designed for use with microphone signals, and have an input sensitivity of -16 dB to -60 dB. Used in conjunction with the 26 dB PAD switches, however, these channels can also be used with line-level signals and "hot" microphone signals. With the pad switch on, input sensitivity is +10 to -34 dB. A detented action allows for accurate repeat setting. The GAIN controls on input channels 13 through 16 are designed for use with line-level signals, and have a gain range of -10 dB to 20 dB. +10 -20 GAIN GAIN control settings are not stored in scene memories.

01V—Owner’s Manual
Phantom Powering
Input channels 1 through 12 feature +48 V phantom powering for use with
condenser-type microphones. Phantom powering is supplied to the bal-
anced XLR-3-31-type connector, and can be switched for inputs 1 through 6
and inputs 7 through 12. Phantom powering should be turned on only when
a condenser-type microphone is connected.
Pad Switches
Input channels 1 through 12 feature 26 dB pad switches. Input pads attenu-
ate the input signal by 26 dB, allowing the input preamp to work with
high-level signals. You may need to use a pad with “hot” signals from bass or
snare drum microphones, or “hot” line-level signals. PAD switch settings are
not stored in scene memories.
Setting Input Channel Gain
GAIN controls adjust the gain of the input channel preamps. They’re used to optimize
the input signal level for the best signal-to-noise performance, and should be set in con-
junction with the level meters on the HOME pages. Ideally, the GAIN control should
be set so that the signal level is relatively high, and it’s okay for it to reach CLIP occa-
sionally. If CLIP is reached often, however, back off the GAIN control a little, otherwise,
signal distortion may occur. The GAIN control should be set with care. If it’s set too low,
the signal-to-noise performance will suffer. If it’s set too high, unpleasant signal clip-
ping and distortion may occur.
The GAIN controls on input channels 1 through 12 are designed for use
with microphone signals, and have an input sensitivity of –16 dB to
–60 dB. Used in conjunction with the 26 dB PAD switches, however,
these channels can also be used with line-level signals and “hot” micro-
phone signals. With the pad switch on, input sensitivity is +10 to –34 dB.
A detented action allows for accurate repeat setting.
The GAIN controls on input channels 13 through 16 are designed for use
with line-level signals, and have a gain range of –10 dB to 20 dB.
GAIN control settings are not stored in scene memories.
Metering Input Channels
Signal levels can be metered on the HOME pages. See “Metering Signal Levels” on page
83 for more information.
Warning:
Make sure that phantom powering is turned off when connecting an unbal-
anced source to an XLR input.
