Mic In
The Mic In jack is a female XLR type and uses a standard XLR cable. Its impedance level and
phantom power supply are controlled from the channel specific front panel buttons. Pin 2 is
hot.
Great River Tips:
Turn the phantom on and off with the microphone connected, this will assure an equal ramp up
and down to both the input transformer of the preamp and the microphone, preventing any
inadvertent magnetization.
Line Out
The balanced line level output jack is a male XLR type and uses a standard XLR cable.
Through its channel specific front panel control, engaging the loading button will activate a
termination resistor. Pin 2 is hot.
Great River Tips:
This output is transformer isolated and balanced. It may be connected to unbalanced inputs by
simply connecting pin 2 to the hot lead and tying pins 1 and 3 together. Do not float pin 3, it must
be connected to complete the circuit.
Patch
This patch jack or insert point jack is a 1/4" TRS (tip, ring, sleeve) type. The Tip is send, the
Ring is return, and the Sleeve is ground. The nominal level is approximately -10dBv.
Great River Tips:
This is a great place to plug in an RNC ™ compressor! The Speck ASC™ also works great here.
You can also plug "stomp box" type effects units into this loop. Obviously the performance of the
chain will be limited by the effects box, but it may be just the sound you want.
-10dBv Out
The unbalanced line level output is a 1/4" TS (tip, sleeve) jack type. This output will drive a
600 ohm load.
Great River Tips:
This output can be used to feed your monitoring system while tracking with a digital system that
has latency issues.
The –10 output is derived ahead of the output transformer, so it has a bit less of the "iron"
characteristic. You might try this output if you are going for a very clean signal. This output won't
put out enough to drive a +4dBu input to full level though, so it won't always be useable.
Power
The NV series preamplifiers are shipped to operate on standard 110Vac. To operate the unit
on 220Vac, first remove fuse and replace with correct size. Then turn the voltage select card
over and replace fuse into the NV series preamplifier.
