section 7 AV PRODUCTION/DISCO APPLICATIONS
Sophisticated switching, and two stereo pre-amplifiers are
features making the 350 ideal for broadcast production or
disco applications.
The two phono amplifiers are totally separate from the audio
electronics of the mixer and may be used independently.
Normally connect the turntable’s phono cable directly to the
preamp input, and its corresponding output directly to the
350 input jack (if trim control is required), or accessory
receive of any input channel.
These pre-amplifiers can also be used as four independent
mono pre-amplifiers.
Observe all the previous instructions for setting levels, and in¬
terconnections. To physically couple a pair of adjacent faders
for stereo use, you may use the optional Model 9900 Fader
Link. You can use the stereo auxiliary buss for echo as
described in section 4, or to provide an independent stereo
mix for foldback, recording or low level PA for a club foyer,
etc. .
Using the four channel buss and associated switching, opera¬
tion and monitoring is greatly simplified.
Use the output buss A and B to feed your master recorder or
amplifier system and reserve C and D for pre monitoring.
Use headphone or amplifier/speaker monitoring, but remem¬
ber that using loudspeakers at high level near a turntable
may cause low frequency feedback, so take care.
Using the four channel buss selector (3), select the four chan¬
nel buss A-B for feeding the signal to the outputs, or C-D for
pre-listen.
In this latter monitor mode, as long as both master faders (11)
are in the same position, you will be able to monitor aurally,
or in conjunction with the optional meter bridge, the exact
level that will appear on the A-B buss when it is selected. The
advantage here is that you can now either: (i) switch the in¬
puts) directly to the output channels A-B with the selector
switch (3), at full level or (ii), know the exact level to which to
fade up if introducing the new signal, using a fade up or cross
fade technique.
An interesting possibility arises due to the inclusion of the
parametric equalizer (8) on each channel. If you have a mono
recording or disc and you are working in stereo, feeding the
same signal to two channels (set recorder to mono or feed
direct out of one channel to accessory receive of another) by
applying differing amounts of boost and cut at different fre¬
quencies, you may simulate a stereo effect from the mono
signal. Adding reverberation to one of the channels will also
enhance the stereo effect.
TYPICAL HOOK-UPS.
A simple hook-up permits you to connect two turntables, a
stereo tape recorder or cartridge machine, and a couple of
microphones to the Model 350.
This arrangement is ideal for an AV Production or disco
system. There are many applications, especially in club situa¬
tions, where it is necessary to control a series of live micro¬
phones as well as a disco function form turntables and tape
decks.
Because the Model 350 has switched inputs (normally intend¬
ed for multitrack recording) these can be used to select
various signal sources.
By feeding the outputs of the phono preamps and stereo
recorder or jingle machine outputs into the “tape in” sockets
instead of the normal input jacks, you can now feed eight
microphones, possibly seven from a stage area and one local
DJ or announcer mike, into the eight input jacks. Using the
input selector switches (1) you can now switch the mixer
between Disco Operation and PA use.
Monitoring techniques follow as above, allowing you to check
input levels, and even stereo balance before being sent out
as program.
