Controls and Functions
INPUT CHANNEL SECTION
The following section details each part of the EXPEDITION EXPRESS’ INPUT CHANNELS including the 2-BAND
EQ, REVERB send, PAN and VOLUME controls. Input channels one through three on the EXPEDITION EXPRESS
feature high quality, discrete transistor pre-amps providing transparency and extended dynamic range.
CHANNEL EQUALIZER
The EXPEDITION EXPRESS’ input channels feature a 2-band equalizer allow-
ing you to adjust the high and low frequencies independently on each
channel. The channel’s frequency response is flat when the knobs are in the
"12:00" position.
HIGH
Rotating the HIGH knob towards the right will boost the treble frequencies
(12KHz) by 15dB, and rotating it towards the left will cut the high frequen-
cies by 15dB.
LOW
Rotating the LOW knob towards the right will boost the bass frequencies
(80Hz) by 15dB, and rotating it towards the left will cut the LOW frequencies
by 15dB.
REVERB
The EXPEDITION EXPRESS provides high quality digital effects, and the
level of effects can be set independently on each channel. The channel’s
REVERB knob controls the amount of signal that is sent to the REVERB bus.
The signal of the REVERB bus is routed to the internal DSP effects section for
onboard signal processing.
PAN (Mono Inputs 1 & 2 Only)
The EXPEDITION EXPRESS’ PAN control is used to place or position the mono
signal into the stereo main Left and Right bus. You can create a stereo image
by panning some input signals to the left and others to the right.
BALANCE (Stereo Input 3/4 Only)
The EXPEDITION EXPRESS’ BALANCE control is used to correct any difference
in level between the stereo main Left and Right MIX bus.
VOLUME
The EXPEDITION EXPRESS’ input VOLUME controls the overall channel level.
The input VOLUME features an audio taper and no detents for smooth
fades.
