8.1 Interface CRM Levels
The DAYNER is ready to interface with all available
equipment in its standard configuration (refer to
section 8.7). One point of attention must be made
concerning the C.R.M. output. This output delivers a
nominal +4dBU level which is sometimes too high for power
amps rated at 300mV sensitivity for full output. In some
cases, an input attenuator at the power amps input is
needed to reduce this +4dBU level up to 12dB.
Contact the D&R Technical Support Department for details.
8.2 The Initial Hookup
First, connect the rackmount power supply (2 supplies come
with the 59 or 84 chassis) to the console. All faders,
monitors, and effect returns must be in the down or off
position. The next steps should be followed in the order
they are printed to assure the best signal to noise ratio
for your system.
a. Connect the C.R.M. outputs (located on the master module
backplate) to the inputs of your control room speaker power
amps. Now turn the console power supply on, then turn the
power amp on and check for any hum, buzz or interference.
Slowly turn the C.R.M. control clockwise until wide open
while still listening for excessive noise or hum. At this
point, you should only hear a faint hiss. If everything is
oke, then continue. If any hum or excess noise is present,
stop and try different ground situations or lifting of
shields until your system is clean.Now procede on to step b.
b. Before making any other connections, turn each monitor
pot to the 3 o'clock position, with the tape switch down on
each monitor section. Now connect the multitrack outputs to
the tape return jacks on the backplate of each In-line
module (line inputs if using Split modules) (refer to
General Audio Installation, section 8.0). Check for hum or
noise after each track is hooked up. The hiss will built up
a little with each track. Then connect the tape send
output jacks to the inputs of the multitrack. Carefully
listen for excessive noise or hum. If by hooking up an input
or output you get excessive noise or hum, stop and try to
find the corrective action before proceding. DO NOT HOOK UP
ALL SIXTEEN OR TWENTY FOUR TRACKS AND THEN LISTEN. You might
need to rewire the entire cable harness to make the system
as clean as possible.
c. Next connect the stereo tape recorders (inputs and
outputs), stereo headphone amp, and all signal processors,
making sure you check for excessive hum or noise with each
input or output.
