supply of the type marked on the unit adjacent to the power supply cord.

17. If this product is to be mounted in an equipment rack, rear support should be provided.

18. Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in suscep­tibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise
for a sufficient time. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has specified the
following permissible noise level exposures:

Duration Per Day In Hours Sound Level dBA, Slow Response

890
692
495
397
2100

1 1⁄2 102

1105

1⁄2 110

1⁄4 or less 115

According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or protectors to the
ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss, if exposure
is in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high sound pressure levels, it is
recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be
protected by hearing protectors while this unit is in operation.

11.. IINNSSEERRTT

This is a female 1/4" TRS connector for
terminating two, single-ended (unbalanced) line level
circuits. The tip is a line output.

22.. LLIINNEE ((BBAALL))

This is a female 1/4" TRS connector for
terminating balanced lower high impedance line level
circuits. Tip is positive, ring is negative. This circuit is
wired in parallel with the female XLR connector. This
input is connected through a 20 dB pad to the Mic
input. Connecting to this input will not disable the XLR
input connector, so both inputs should NOT be used
simultaneously.

33.. MMIICC

This is a female XLR connector for terminating
balanced, low impedance microphone circuits. Pin 2 is positive and +48 V DC
is applied to pins 2 and 3 via a resistive network when the front panel
Phantom Power switch is ON.

CChhaannnneell SSttrriipp CCoonnttrroollss

44.. GGAAIINN

This control adjusts the first gain stage of the input channel. The
range is +10 to +56 dB for microphone level inputs and -10 to +36 dB for line
level inputs. The output of this gain stage also drives the SIG/PFL LED.

55.. LLOOWW CCUUTT

This control adjusts the setting of the low cut filter and is
variable from no cut in the OFF position, to cut below 300 Hz in the
maximum position.

66.. HHII

This active tone control is a shelving-type that varies high-frequency

response by +/-15 dB in the range above 12 kHz.

77.. MMIIDD

This active tone control is a bandpass (peak/notch) type that varies

mid frequency response by +/-15 dB in a range from 200 Hz to 6 kHz.

88.. MMIIDD FFRREEQQ

This control determines the center frequency of the MID
control. Center frequency for the bandpass filter can be set from 200 Hz to
6 kHz.

99.. LLOOWW

This active tone control is a shelving-type that varies low frequency

response by +/-15 dB. Corner frequency is 75 Hz.

1100.. AAUUXX 11 -- 44

These controls adjust the level of the channel’s pre-fader
signal that is sent to the auxiliary mix. Gain is variable from minus infinity
(– ∞) to +10 dB. Unity gain is at the center detent position.

1111.. AAUUXX 55 -- 66

These controls adjust the level of the channel’s post-fader
signal that is sent to the auxiliary mix. Gain is variable from minus infinity
(-∞) to +10 dB. Unity gain is at the center detent position.

1122.. PPAANN

This control determines the signal’s position with respect to L/R
and Sub 1 - 4 outputs. Rotating the control counterclockwise increases the
amount of signal sent to L and odd-numbered Subs; rotation clockwise
increases the amount sent to R and even-numbered Subs.

1133.. AASSSSIIGGNN SSWWIITTCCHHEESS

These post-fader, post-EQ switches determine where

the channel signal is being sent.

1144.. MMUUTTEE SSWWIITTCCHH aanndd MMUUTTEE//CCLLIIPP LLEEDD

This switch mutes all Aux, Sub, L/R,
and Mono sends from the corresponding channel. The switch is equipped
with a red LED that will illuminate when the channel is muted. When the
Mute switch is disengaged, the LED functions as a clip (PK) indicator that
will illuminate at 2 dB below clipping. Muting the channel does not prevent
the PFL signal from being sent to the PFL mix when the PFL switch is
engaged.

1155.. PPFFLL SSWWIITTCCHH && SSIIGGNNAALL//PPFFLL LLEEDD

This switch connects the channel’s pre­fader signal to the PFL mix. With this feature engaged, the channel’s signal
can be monitored through the headphones and/or on the AFL/PFL display.

The adjacent amber LED will illuminate to indicate that the channel’s signal has been assigned to
the PFL mix, and an amber LED in the Mono Master section will blink to indicate that the signal on
the Mono LED display and at the Headphone Out is PFL. When the PFL switch is not engaged, the
Signal/PFL LED will blink as an indication of signal presence (-20 dBu) on the channel.

1166.. CCHHAANNNNEELL FFAADDEERR

This control determines the level of the channel’s signal that is sent to L/R,

Sub, and/or Mono. The range of the fader is (- ∞) to +10 dB, with unity gain at the 0 dB mark.

Input connections and channel strip controls on Super Channels are the same as Standard Channels
with the exception of Insert jacks. In place of Insert connections, Super Channels are equipped with:

1177.. PPAADD

This switch attenuates (reduces) the input signal by 20 dB. This
allows accommodation of higher input levels without clipping and is
especially useful when close-miking high sound pressure level (SPL) sources.

1188.. PPOOLLAARRIITTYY

This switch reverses the polarity of both the XLR and LINE
input connectors to compensate for an out-of-phase signal that would
otherwise cause frequency (phase) cancellations in the mix.

Stereo Channels offer the same channel strip controls as Standard Channels
with the exception of the Mid Frequency control. Center bandpass frequency
is set at 850 Hz. In place of the Mid Frequency control, Stereo Channels offer
independent gain controls for the Line and Mic (XLR) inputs. Stereo Channels
also include:

1199.. SSTTEERREEOO 11//44"" LLIINNEE IINNPPUUTTSS

These TS jacks are unbalanced line level
inputs for stereo (L/R) signals. They are connected in parallel with the Stereo
RCA Line Inputs. For Mono line sources, use a Y cable or one of the channels
with a MONO line input.

2200.. SSTTEERREEOO RRCCAA LLIINNEE IINNPPUUTTSS

These RCA (phono) inputs are unbalanced line
level inputs for stereo (L/R) signals. They are connected in parallel with the
Stereo 1/4" Line Inputs.
