Caution!
The RCA connector accepts unbalanced or single-ended signal from
preamplifiers with RCA outputs. If your preamplifier has both RCA and
XLR outputs, use the XLR output. Set the toggle switch to the position
closest to the RCA connector.

The N -536 amplifier utilizes custom-made, gold-plated, high-current
loudspeaker binding posts. The positive binding posts, labeled + (positive),
Posts
are red; the negative binding posts are black and are labeled – (negative).
Two of each binding post are present on the N
compatible loudspeakers. If your loudspeakers support bi-wiring, connect
both red (positive) terminals to the red terminals on the loudspeaker, and
connect both black (negative) terminals to the black terminals on the
loudspeaker.
If your loudspeakers do not support bi-wiring or you prefer not to employ
this connection configuration, simply connect one of the positive and one
of the negative terminals to the respective loudspeaker terminals. There is
no additional configuration needed to disable bi-wiring output capability.
Banana plugs can also be used to connect the speaker cables to the
loudspeaker binding posts. Banana plugs are not available on the
230 VAC model.
Note
Ensure when connecting the loudspeaker that at least one positive and one
negative binding post is used. There is NO ground reference.
Be careful to not short the positive and negative outputs together.
Do not short the positive or negative outputs to chassis or any other
safety ground. The amplifier must be powered off during installation
and whenever input and/or output cables are being connected. This
is a balanced amplifier and all binding posts are active at all times.
Do not attempt to connect any binding posts to ground.
DO NOT OVERTIGHTEN the binding posts. The innovative design
of these binding posts provides more leverage; hence, high-contact,
tight pressure connections are achieved when finger-tightened.
DO NOT FORCE the binding post "wings" over a bent or oversized
connector. Doing so may damage the binding post.
