1. Operation
The NX750P is a bi-amped powered full-range
loudspeaker with a built-in two channel mixer.
Multiple NX750P cabinets may be connected
through the Link option. If you’re using the
NX750P with an external mixer, the internal
mixer can be disabled. The built-in mixer has
a microphone input and two (combined) ¼
inch inputs for line sources such as CD players.
Advanced signal processing is used to give
maximum performance at all levels. There’s a
switch to provide a low frequency rolloff if you’re
going to use the NX750P with a subwoofer.
2. Mic Input
Any regular microphone can be inserted into
the Mic input. Phantom power is built–in for
condenser microphones.
3. Line/CD Inputs
The Line/CD inputs allow line level sources such
as CD players or Cassette decks to be directly
connected. These inputs are combined to
allow the blending of stereo sources into
mono. The inputs are also balanced to help
reject hum (when used with balanced cables).
This input may be used to allow operation from
lower-level Line inputs (as opposed to the Link
jacks). It may also be used to accommodate
a greater range of level adjustment than the
NX750P Level control allows (for example a
cabinet in a chain of cabinets that needs to
operate at much reduced level).
4. Link
These parallel jacks allow multiple NX750P
cabinets to be connected together. The Link
Jacks are the correct input to use when driving
the NX750P from an external mixer. The Link
Jacks operate at line level (+4 dBv) to achieve
full power. The NX750P Level control allows
operation at levels from –2 dBv to +10 dBv for
full power. When operating from signals that
are not as strong, use the Line inputs of the
first cabinet in the chain. The Link jacks are
high quality balanced inputs with very good
common mode (hum) rejection. To ensure
maximum hum rejection, the proper balanced
cables must be used. Jacks marked LINK
OUTPUT are connected in parallel with the
LINK INPUTS and are provided for convenience
to connect downstream cabinets. Link inputs
may also be used as outputs and link outputs
may be used as inputs.
5. Connections
When using the NX750P in the angled position
(i.e. as a stage monitor), it is recommended
to use jacks that have 90-degree connectors.
This will reduce the risk of damaging the wires
by being bent and/or pinched.
6. Level Control
This control allows cabinets, linked in a chain,
to be individually adjusted over a +/- 6 dB
range.This control does not adjust the level of
the Link jacks.
