IQ–P.I.P.-MEM Programmable Input Processor for IQ Systems
IMPORTANT: Two switch
segments (S1, S2) are re-
quired for each setting. Be
careful to use both seg-
ments or improper operation
will result.
Switch S1 configures the in-
put to Channel 1 and switch
S2 configures the input to
Channel 2.
CAUTION: The IQ–P.I.P.-
MEM input preamplifiers
should only be used with
microphone or low-level
signals. Once the PIP is in-
stalled, there will be no out-
ward indication of the input
preamplifier gain setting.
The protection circuitry of
the amplifier will probably be
activated if the preamplifier
gain is set to 40 dB and a
line-level signal is con-
nected to the input. If your
amplifier appears to “cut
out” when you drive it with a
strong input signal, check to
see if the input preamplifier
gain is set too high.
Recommendations: Attach
a small label to the back of
the PIP to identify whether it
has been set for microphone
or line-level input signals.
And keep the output levels
low if you are uncertain of
the preamplifier settings.
Remember, Crown is not li-
able for damage due to
overpowering other compo-
nents.
