MONO MIC / LINE CONTROL FUNCTIONS
C. LEVEL – Adjusts the volume level of the individual
channel. Rotating the knob clockwise increases the
respective channel's contribution to the "Main Out" mix,
while rotating it counterclockwise decreases the
volume. Adjust this control after the Passport's master
output level volume has been set.
D. VIP (CHANNEL 1 ONLY) – The VIP or Vocal Input
Priority control adjusts the level at which the volume of
all other channels are automatically reduced in favor of
the source attached to the Mic/Line Input 1. This unique
feature permits a user to speak while other inputs (such
as background music) continue at temporarily reduced
levels. The VIP circuit is "pre-volume control" which
means it is effective regardless of level control setting of
channel one. Adjust this control while speaking into a
microphone on channel 1, with other program material
input through another channel. Depending on the
duration and level of the signal being input to Mic/Line 1
and the position of the control, the VIP circuit will trigger
a reduction in level of all the other channels. The original
levels will be automatically restored when there is no
signal present on channel 1. In typical use, the circuit will
return normal levels in about 4 seconds. With the level
set at a higher or a stronger signal, normal levels will be
restored after approximately 6 seconds. The VIP circuit
has an intentionally slow release time which prevents
interruptions when a speaker pauses for thought or
effect. Care should be taken to avoid the VIP triggering
on sound from the main speakers. At high settings, the
microphone may "hear" the main system speakers and
trigger a reduction in level. When not using the VIP
feature, be sure to turn the control completely
counterclockwise.
E. EQ – Adjusts the amount of frequency increase or
decrease
in
the
channel.
counterclockwise increases the bass frequency
response while simultaneously decreasing the high
frequency response. Likewise, rotating the knob
clockwise increases the treble or high frequency
response while simultaneously decreasing the bass or
low frequency response. When the tone controls are set
at their notched or straight up position, the channel
response is "flat" with no frequencies increased or
decreased. To set the EQ, start with this control in the
12 o'clock (notched) position. Simply turn the control
until things sound good!
F. REV/AUX – Adjusts the amount of signal sent to the
Reverb processor, and to the Rev/Aux output jack.
Reverb can be used to enhance the sound quality of any
performance where appropriate and desired. In the full
Rotating
the
knob
left position there is no level sent to the reverb processor
or Rev/ Aux jack. Care should be taken to set the
Reverb return master control to a middle position or
above, before adjusting levels from the individual
channels. When the reverb/auxiliary mix is set, overall
levels of reverb can be adjusted at the master control.
Keep in mind that while Reverb or effects can enhance
a musical performance or presentation. Too much
reverb can make the same performance or presentation
unintelligible or "muffled". Keep your audience in mind
when setting reverb levels.
G. PAN – The Pan control features a notched position
indicator and adjusts the perceived "position" of the
mono signal from the input within the stereo field
created by the two speaker cabinets. Full Left or Right
rotation of this control sends the signal to the that
channel only, with no signal sent to the other. The center
position sends the same amount of signal to both
STEREO CONTROL FUNCTIONS
speakers.
C. STEREO INPUT LEVEL – Adjusts the volume level
of the stereo input channel. Rotating the knob clockwise
increases the stereo input channel's contribution to the
"Main Out" mix, while rotating it counterclockwise
decreases the volume. Adjust this control after the
Passport's master output level volume has been set.
E. EQ LOW – Adjusts the relative level of the low
frequency content for the stereo channel. Rotating the
knob counterclockwise decreases the bass or low
frequency response. Likewise, rotating the knob
clockwise increases the bass or low frequency
response.
E. EQ HI – Adjusts the relative level of the high
frequency content. Rotating the knob counterclockwise
decreases the treble or high frequency response.
Likewise, rotating the knob clockwise increases the
treble or high frequency response. When the EQ
controls are set at their notched or straight up position,
the channel frequency response is "flat" with no
frequencies increased or decreased.
