Peavey 900 - Page 6

justec to track the 900 VU meter with a constant input
signal, i.e.. set the 900’s meter to read “0” VU at the
same level as the external equipment’s VU does. With
equipment that has LED overload indicators, the900's
meter should be set to zero VU at the point where the
LED peak overload indicator initially lights up.
If the equipment being fed by the 900 has no max¬
imum level indicator you should refer any adjustment of
VU meters to a properly equipped sound technician to
avoid problems in matching VU readings with maximum
output and/or modulation.
You should be aware that we have designed the
900 Mixer to be able to drive power amplifiers with
VERY low input sensitivities of 2 volts or higher
Because of the high output capability of the 900, it may
appear that the 900 is excessively noisy when plugged
into power amplifiers with high input sensitivity such as
the Peavey 260 or 800 Boosters which require only %
volt for FULL output. The extra gain designed into the
900 to allow use with the less sensitive power amps
should NOT be interpreted as poor design but as ad¬
ditional gain capability. It is possible to use "high gain”
power amps with very good results by generally using
less channel and master gain, or by decreasing the
power amp’s sensitivity by turning down the power
amp’s level control
REAR PANEL - The 900 Mixer rear pane features
a complete patching panel for various output and input
functions, as well as the microphone input connectors
for each channel.
Each channel's input connecters are labeled with
its identification number, as well as an indication of
whether the input is for high (16) or iow (17) impedance.
The high impedance connectors are standard phone
jacks. The low impedance connectors are of the can¬
non type, three conductor connector to be used for low
impedance microphones only, and will accept 150 to
600 ohm mics.
CAUTION SHOULD BE USED NEVER TO USE
THE LOW IMPEDANCE INPUT AND THE HIGH
IMPEDANCE INPUTS OF ANY ONE CHANNEL
SIMULTANEOUSLY.
AUXILIARY INPUTS - There are three auxiliary in¬
puts on the 900 Mixer
The MAIN AUXILIARY INPUT (18) is the input to
the main mixing buss of the 900 Mixer. This input mixes
a signal with the mam buss at the same point as the in¬
dividual channels and may be used when patching two
mixers together, or whenever an additional signal is
added to the mam mix. The mam auxiliary input can
also be thought of as an additional channel and can
even be used with a high impedance microphone as a
signal source.
The MONITOR AUXILIARY INPUT (19) is the in¬
put to the monitor mixing buss of the 900 Mixer. This in¬
put mixes a signal with the monitor buss at the same
point as the individual channels and is to be used when
patching two mixers together or any time access is
needed to the monitor buss in order to place a particular
signal in the monitor system.
The EFFECTS AUXILIARY INPUT (20) is the input
to the effects mixing buss of Ihe 900. This input mixes a
signa with the effects buss at the same point as the in¬
dividual channels and is to be used when patching two
mixers together or any time access is needed to the
effects mixing buss.
The EFFECTS RETURN (26) is the input jack for
patching in external signals of various kinds. This input
is high impedance with adequate gain to handle low
level signal sources such as certain echo units and high
impedance mics Actually, this input is an additional
channel without equalization or sends that feeds into the
main mixing buss as do the other channels. The level
control for this input is the Effects Return (15) located in
the front panel master section.
The MAIN OUTPUTS (21) are located on the rear
panel and are standard V* phone jacks. The outputs are
