WARNING: When using electrical products, basic cautions should always be followed, including the following:
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any of the ventilation openings. Install in accordance with manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves or other apparatus (including
amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug.A polarized plug has two blades with one
wider than the other.A grounding type plug has two blades and a third grounding plug.The wide blade or third
prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the
point they exit from the apparatus.
11. Only use attachments/accessoriegs provided by the manufacturer.
12. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer or sold with the apparatus.When
a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in
any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
15. Never break off the ground pin.Write for our free booklet “Shock Hazard and Grounding.” Connect only to a power
supply of the type marked on the unit adjacent to the power supply cord.
16. If this product is to be mounted in an equipment rack, rear support should be provided.
17. 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 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
2 100
1 1/2 102
1 105
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.

features
+48 V
+48 volts DC is applied equally (through current-limiting resistors) to both
pins 2 and 3 on the mic-input XLR connector.This feature is used with condenser
microphones and active direct boxes that require an external DC voltage (phan-
tom power) in order to operate.
For dynamic or ribbon mics, phantom voltage is not required and should be
switched OFF.
NOTE 1: Operating this switch (On or Off) causes large voltage swings to occur
at the input of the mic preamp. Care should be taken to insure that the channel
is muted or the main faders are pulled down to prevent this POP from getting to
someone’s ears.
pad
The XLR-input signal is attenuated by 25dB to prevent strong signals (e.g. kick
drum or lead vocal) from overloading the preamp stage.The pad is used to bring a
hot mic-input signal down to a controllable level, or when a line-level signal is pre-
sent at the XLR input jack.
gain
The Input gain control range is closely related to the status of the PAD switch.
In order to establish proper gain structure in the console, input gain settings
must be set correctly. Use the PFL switch and Solo system to properly set the gain
of the channel.
PAD—switch-up
4 to 60dB of gain can be added the XLR-input signal.
The impedance at the input XLR is 2.5kΩ.
PAD—switch-down
-21 to 35dB of gain can be added to the XLR-input signal.
polarity (reverse)
This feature is used for correcting or minimizing polarity and phase related errors.
For example, occasionally a balanced input connection is reverse-wired before it
gets to the mixing console.This can happen in microphones, or in snake line inter-
faces. By using the polarity button, this type of error can be corrected.
normal polarity (Pin 2 Hot)
polarity reversed (Pin 3 Hot)
If the channel peak
LED is illuminated,
first try lowering
the input gain control.
Only when this method
is unsuccessful should
the pad switch be
engaged.
+
1
When similar sig-
nals from different
channels are combined,
phase cancellations can
occur.
Reversing the polarity of
an input signal can often
minimize such phasing
errors.
+
The 48V switch
should
not be engaged when
using standard (dynam-
ic) microphones, or
other sources that do
not use phantom power.

Lo-Cut filter
This filter reduces or eliminates unwanted low frequencies without substantially
affecting the program material. Quite often, such unwanted low frequencies are
included with mic- or line-input signals. For example, stage rumble or wind can
be picked up through vocal mics.The cut-off frequency of the filter is 72 Hz and
the slope is -18dB per octave.This type of filter is also referred to as a Hi-pass
filter (HPF). It allows the hi-frequencies to pass, but stops the lo-frequencies.
Lo Cut Switch
Lo-Cut filter is bypassed.
Lo-Cut filter is on.
1
When performing
outdoors, wind-
induced, low-frequency
rumble can get into the
input channels thru the
microphones.
Engaging the Lo-Cut fil-
ter can eliminate these
power-stealing low fre-
quencies.

EQ features
Many audio signals coming into the console require some degree of corrective
equalization in order to be part of a good sounding mix.
The input EQ consists of four-bands: high, high-mid, low-mid and low.
The high and low bands have fixed frequencies while the high-mid and low-mid
bands are sweepable, with their higher and lower frequencies overlapping adja-
cent bands.
high frequency—HF
15dB boost and cut at 12kHz—Shelving Response.
high-mid frequency—HM
Selectable frequency range of 500Hz to 10 kHz.
The response is bell-shaped with a fixed Q of 1.5
15dB boost and cut centered at the selected frequency.
low-mid frequency—LM
Selectable frequency range of 100Hz to 2kHz.
The response is bell-shaped with a fixed Q of 1.5
15dB boost and cut centered at the selected frequency.
low frequency—LF
15dB boost and cut at 80Hz—Shelving Response.
eq on
Equalizer is off. The EQ circuits are bypassed.
Equalizer is on. This switch can be used to make A/B comparisons between
"flat" and eq'd signals.

aux send features
Ten aux sends are available for creating individual output mixes.These mixes can
be used for driving effects processors, providing monitor mixes, creating broad-
cast or alternate sound reinforcement mixes, or other special requirements.With
the corresponding PRE switches in the UP position, the Aux sends are fed from
the Post-fader channel signal. When the PRE switch is depressed, the corre-
sponding Aux sends are fed from the Channel’s Post-EQ, Pre-fader signal. An
internal option allows the user to change this “PRE” point to the Pre-Insert, Pre-
EQ signal on a channel-by-channel basis.All Aux sends are affected by the chan-
nel Mute switch.
aux sends 1–6
These knobs adjust the amount of signal sent to the corresponding AUX
buses. Unity gain occurs at the zero setting, with 6dB additional gain available
above that.
PRE (aux 1–6 )
The default signal source for these Aux sends is post-fader.This switch is used for
selecting the Pre-fader signal for Auxes 1-6.The normal Pre-fader signal is derived
Post-EQ.
see internal jumper options
Aux sends are Post-EQ, Post-fader.
Aux sends are Post-insert, Post-EQ, Pre-fader.
aux sends 7-8 and 9-10
These knobs adjust the amount of signal sent to the corresponding AUX
buses. Unity gain occurs at the zero setting, with 6dB additional gain available
above that.
PRE ( aux 7–8 & aux 9–10 )
The default signal source for these AUX SENDS is post-fader.These switches are
used for selecting the Pre-fader signals for Auxes 7-8 & 9-10.The normal Pre-
fader signal is derived Post-EQ.

bus assignment features
The Input bus assignment section offers considerable flexibility for creating what even-
tually becomes the main output mix. Channels can be assigned to the independent
Mono bus, the pan-paired Left/Right buses, or any of the pan-paired subgroups (1-2, 3-
4, 5-6, 7-8).All assignments are derived post-fader, post-eq, and post-mute.
pan control
The pan control positions the post-fader channel signal within the stereo left-right field,
or between the Odd and Even groups of an assigned pair.The signal is down by approx-
imately -3dB at the center-detent position when panning across the buses.
Bus Assign
M (Mono)
Assigns the post-fader channel signal to the Mono Bus.The pan-pot position does not
affect the signal to the Mono bus.
L-R (Left- Right)
Assigns the post-fader, pan-pot signals to the Left and Right Buses.
1-2 (Groups 1-2)
Assigns the post-fader, pan-pot signals to the Group 1 and Group 2 Buses.
3-4 (Groups 3-4)
Assigns the post-fader, pan-pot signals to the Group 3 and Group 4 Buses.
5-6 (Groups 5-6)
Assigns the post-fader, pan-pot signals to the Group 5 and Group 6 Buses.
7-8 (Groups 7-8)
Assigns the post-fader, pan-pot signals to the Group 7 and Group 8 Buses.
channel fader
The channel is fitted with a high-quality, 100mm fader. Normal mixing range is around
the “0” mark,with up to 10dB fader-boost available when needed.All Post-fader feeds
from the channel are controlled by this fader (Post Aux sends, Bus assignments).
