BUTTONS AND CONTROLS (See page 59,60)
@) INPUT SELECTOR SWITCH (Channels 1-4)
These switches select the source of input to the mixer section.
MIC/LINE
In the Mic/Line position, the input for that channel will come from the back panel XLR or 1/4" jack
for that channel. See also the XLR switch,
OFF
The off position is used to mute all input to that channel.
TAPE
When Channels 1-4 have “Tape” selected as their input source, the corresponding tape track will be
routed to that channel, instead of the Mic or Line source plugged into the back. For example, if channel
3 is set to “Tape” input, then channel 3 will get it’s signal from tape track 3, regardless of what is
plugged into Mic or Line input #3 on the back panel.
(2) DIRECT ASSIGN SWITCH (Channels 5 and 6)
The Direct Assign switch allows you to route the output of channels 5 and 6 directly to one track,
before being mixed with other channels, effects, etc. This is useful for recording an isolated signal
on a track of it's own, while still being able to hear it in the mix.
Channel 5
The Direct Assign Switch for Channel 5 has three positions: TRK 1, DIRECT OFF (L/R) and TRK 3.
Channel 6
The Direct Assign Switch for Channel 6 has three positions: TRK 2, DIRECT OFF (L/R) and TRK 4.
@) XLR SWITCH (Channels 1-4)
These switches are found only on the first four channels. When they are in the BAL (down) position,
the channel is expecting input from its XLR connector. When in the UNBAL (up) position, the channel
will expect input from its 1/4" connector. Both can be used for either mic or line level inputs.
@ TRIM CONTROL
When the channel input selector is set to TAPE, this knob has no effect. The TAPE input level is
fixed.
When the input selector is switched to MIC/LINE, these controls adjust how much signal goes from
the channel input jack (on the back panel) to the preamplifier for that channel. This is only the first
“gain stage” for the channel. If you use this control to set a “rough” volume level, you can use
other controls for finer adjustment.
(©) Hl EQ/LOW EQ CONTROL
These Equalization controls are found on each of channels 1-6. They control the High (Treble) and
Low (Bass) frequency content of the signal on that channel.
© MID EQ GAIN (Channels 1-4)
Like the HI and LOW EQ controls, the MID EQ has control! over amplification and attenuation (sométimes
called boost and cut) of a range of frequencies.
@ MID EO SHIFT (Channels 1-4) ;
The HI EQ affects all frequencies above a certain “hinge” frequency (10 KHz). The .LOW EQ affects
all bands below a certain “hinge” frequency (100 Hz).. The MID EQ affects a group, or “band” of
frequencies in between.
The MID EQ SHIFT control sets the middle point, or “center frequency” for this band. If this control
is turned all the way to the left, then the MID EO GAIN will control a band of frequencies centered
around approximately 160 Hz. If this control is turned all the way to the right, then the MiD EQ GAIN
will control a band of frequencies centered around approximately 7.5 KHz.
