6-ZONE STEREO AUDIO DISTRIBUTION AND
SOURCE SELECTOR
MODEL SP-6
The NuTone SP-6 is a six zone stereo audio distribution and
audio source selector, which allows 6 pairs of speakers to
share one of two audio sources. Input impedance is kept
within a safe operating range even with all six pairs of
speakers selected. Power handling capacity: 180 Watts
RMS per channel. 360 Watts per channel (Program).
Example: A TV with speaker outputs and a stereo receiver
can be connected to six pairs of speakers located
throughout the house. Audio from either the TV or the stereo
receiver can be distributed to any combination of these
speaker pairs. (Refer to Figure 1)
Installation
IMPORTANT: NuTone is not responsible for any damage
resulting from use of a non-NuTone product and/or failure
to follow installation instructions provided by NuTone.
Note: If 4 ohm speakers are going to be used, the
amplifiers connected to the SP-6 must be capable of
driving a 4 ohm load.
1. Switch the power off to the two audio sources and set
the main volume on each to minimum.
2. Run one pair of 16 AWG wire from each speaker to the
location of the SP-6.
3. Run two pairs of 16 AWG wire from each of the audio
sources to the location of the SP-6.
Note: For convenience indicate: audio source, speaker,
left channel, right channel, and polarity on each cable
run.

4. Once the cables have been run between all the
components strip approximately 1/4˝ of insulation off the
ends of each wire. Twist the ends of the wire and insert
into the corresponding terminals on the SP-6. Be sure
proper polarity is maintained. Be sure no shorts exist
between any of the wires. (Refer to Figure 2)
5. Connection of a volume control (SVC-101 or SVC-102) to
the SP-6 should only be made on the speaker outputs and
never on the source input terminals. Refer to the volume
control's installations instructions for detailed information
on installation.
