Placing Your Ceiling Speaker
for Dual Channel Stereo Operation
Placement can make all the difference in how your speaker will
sound, and how easy it will be to install. Carefully consider where
your speaker should be positioned. For optimum dual channel
stereo performance, the speaker should be mounted as close as
possible to the center of the main listening area as shown in Fig. 2
position 1. (Note: Set switch to 8 ohm mode, and connect left and
right channels from your receiver to the two sets of input terminals
on the speaker, as shown in Fig. 4B.)
For Rear Center Surround
or Single Channel Surround Operation
For surround rear center, mount the speaker as shown in Fig. 2
position 2. (Note: Set switch to 8 ohm mode, and connect the two
rear channel outputs from your receiver to the two sets of input
terminals on the speaker, as shown in Fig. 4B.) Avoid mounting the
speaker in stud cavities containing electrical wiring, heating ducts,
water pipes, etc. Make sure the wall or ceiling materials are sturdy
enough to support the weight of the speaker. Since the NX-Si8522
is also designed to be used as a single channel speaker with wide
dispersion, it makes a superb surround sound rear or side speaker.
You can mount the unit in the ceiling slightly in front of or behind
the listening position, left and right, as shown in Fig. 2 positions 3
and 4. (Note: Set switch to 4 ohm mode, and connect ONLY one
channel from your receiver to only one set of input terminals on
the speaker, as shown in Fig. 4A.)
Tweeter Level Adjustment (Fig. 1)
The tweeter level switch allows you to tailor the speakers’ frequency
response to better match the room’s acoustics. As an example, if
a room has a hardwood floor, which makes it acoustically brighter
sounding, you may want to adjust the tweeter level control to
compensate. The nominal factory setting with the switch set to 0
represents a flat acoustic response. Switching the control to –3
will reduce the high frequency output for bright sounding reflective
rooms. You can experiment with the level to find the sound that’s
most pleasing to you in your particular listening environment.

Direct/Diffuse Operating Mode Switch
Direct Diffuse Operating Mode Control (Fig. 1)
Set the switch in the “direct” position for normal stereo, dual-channel (right/left) operation.
Set the switch in the “diffuse” position only for home theater (single channel) surround oper-
ation. With the switch set in the diffuse mode the NX-Si8522 will create a sound null on axis
and produce the illusion of a wider sound field, which is desirable for surround operation.
