A. Master Output Level Controls, Left/Main,
Right/Monitor
∆
For the majority of applications the Passport system
has been balanced to operate with these controls at
their notched 12 o’clock positions. In situations
where more “gain” is required, for example where a
microphone (s) is at some distance from the user and
more volume is required than can be reached with
the input channel level controls, the master controls
give an additional 6 dB of gain. Set the system up in
the normal manner and adjust levels as necessary.
Should more overall sensitivity be required the master
controls can be raised. Care should be taken to
avoid feedback, or howling. The Master controls
feature notched position indicators.
If possible always operate the Master controls in their
notched position. Should the overall mix level need
to be increased or reduced when the system is set up
and balanced, the Masters can be rotated to any
position that work under the circumstances.
B. Mode Select Switch & Function
The Mode switch enables the Passport System to be
re-configured for stage monitor applications. With
the Mode switch in its upper position operation is
normal - L-R Stereo.
(This configuration covers 90%
of normal use.).
With the switch in its lower position
the Passport functions as a mono “house” (audience)
mixer, with a separate monitor mix. The mono/house
mix is derived from the channel sends, the Pan and
balance controls becoming inoperative, and the Left
Master becomes the mono - House Master control.
Now a separate mix can be created by using the
REV/AUX send controls on each channel. Set up
your house mix first. The monitor mix level is created
from the channel REV/AUX send control, and then
routed directly to the Right Master Level Control.
Reverb is not returned to this “Monitor” mix. Reverb
is available to the house (Main) mix bus only, however
the reverb level sends are also controlled from the
channel REV/AUX level controls. Reverb level to the
Left Master, now the house mix, is as normal,
controlled from the Reverb Master.
Connect the House speakers to the Left-Main
speaker connectors and the Monitor speakers to the
Right-Monitor connectors.
C. Master - Reverb
The Reverb Master controls the overall amount of
signal that is returned from the digital reverb
processor section to the Left and Right mix busses.
(Note: see Mode Switch operation)
The Passport Sound System features an 8 bit digital
reverb, intended to provide enhancement for vocals
and musical instruments. This reverb system has
been optimized for use across a wide variety of
applications. Relative mix levels to the reverb
processor are adjusted at the individual input channel
Rev/Aux Send controls. The overall mix sent to the
digital reverb section is processed and returned to the
Reverb Master control and after its level is set to the
main mix busses.
Caution should be exercised to avoid overloading the
reverb bus. If reverb is desired on one or more input
signals, set the Reverb Master to a central position
and bring up the input channel reverb send control
until the desired level is reached. Avoid having the
Reverb Master too low with the channel sends in high
positions.
