smooth side of the socket. Don’t force the scalloped side of  
the connector plug into the smooth side of the socket. See  
Figure 2.  
Installation Considerations  
Calculating the Impedance Magnification Setting  
Use the following instructions to select the correct switch  
setting for the number and type of speakers in your system.  
The inputs of the TVC-1 are the connector terminals labeled  
“AMPLIFIER”. The outputs are the connector terminals  
labeled “SPEAKERS”. Be sure not to reverse these connec-  
tions or the TVC-1 will not function properly.  
CAUTION! EVERY SPEAKER PAIR IN THE SYSTEM MUST  
BE CONNECTED TO AN IMPEDANCE-MAGNIFYING VOL-  
UME CONTROL AND SET TO THE SAME MAGNIFICATION.  
1. Count the number of pairs of speakers you are connecting  
to the system.  
8. Locate the pre-printed Room Labels. Affix the appropriate  
label to the recessed area next to the knob on the TVC-1.  
2. Set the Speaker Pairs switch on the rear panel of the TVC-1  
to match the number of pairs of speakers (1, 2, 3/4, 5/6).  
TVC-1 Power Handling  
The TVC-1 is designed for use with a receiver or amplifier hav-  
ing a maximum power output of 100 watts per channel at  
8 ohms. Damage caused by the use of a higher-power receiv-  
er or amplifier will void the warranty. Consult your Niles deal-  
er, or receiver/amplifier manufacturer, if you are uncertain  
about the power rating of your receiver or amplifier.

Mounting Location  
“TECH TIP”  
Convenient mounting locations for the TVC-1 are:  
• With other stereo components  
• Near a desk  
Recessed

room labels.  
• At your bedside

• Close to a telephone

Installation  
1. Select a convenient location for the TVC-1.  
12 position volume control  
(American  
Wire Gauge)  
provides greater attenuation  
than conventional 10 position  
designs.  
2. Run all the necessary wiring to the TVC-1. Label the wires  
for future reference. See (Figure 1).  
number. The lower  
the AWG number,  
the larger the wire,  
i.e., 12 AWG wire  
is physically larger  
than 14 AWG.  
3. Locate the connector plugs (and remove them if they are  
plugged in). See Figure 6.  
4. Strip 1/4" of insulation from the end of each wire. Tightly  
twist the end of each wire until no frayed ends remain.

6. Insert each wire into the appropriate hole on the removable  
connector plug, and snap the locking tab down.  
Type of Speaker Wire  
For most applications, we recommend you use 16 or  
18 gauge, stranded copper speaker wire for the TVC-1 con-  
nections. For wiring runs longer than 80 feet, 14 gauge wire  
is recommended. Using speaker wire larger than 14 gauge for  
the TVC-1 connections is not recommended—the wire may  
not fit into the connectors. Never use solid-core, aluminum,  
or “Romex” type wire with the TVC-1. When running speaker  
wires inside walls, most states and municipalities in the U.S.  
specify that you must use a special type of speaker wire .  
Usually, the requirement is that the wire has a specific “CL”  
fire rating, such as “CL-2” or “CL-3”. Consult your Niles deal-  
er, building contractor, or local building and inspection  
department if unsure about which type of wire is best for  
your application.  
NOTE: To help you avoid improper installation, the  
connector plug is keyed.

IMPORTANT  
Niles TVC-1  
DO NOT use the  
TVC-1 with amps  
or receivers rated  
at more than 100  
watts per channel  
RMS at 8 ohms.  
Avoiding Interference  
Niles Audio Corporation Miami, Florida USA  
Speaker wires can act as an “antenna” for electrical noise.  
Locating speaker wires too close to a light dimmer or switch  
may cause a “buzzing” or "popping" sound to be heard  
through the speakers. If you must locate the TVC-1 wiring  
near electrical devices, route the speaker wires several feet  
away from the electrical wiring.

Operation  
1. Make sure the amplifier or receiver power is OFF and set the  
volume to minimum.  
Features and Benefits  
2. Set the TVC-1 volume to maximum (fully clockwise).  
The TVC-1 offers a number of improvements over other  
tabletop volume controls:  
3. If you are using a Niles speaker selection system, locate the  
on/off button which corresponds to the speaker pair you  
wish to play. Set it to the ON position.  
• Power handling: 100 watts per channel RMS; 200 watts peak  
• Selectable impedance magnification for 1, 2, 3/4, 5/6 pairs  
of speakers  
4. Turn on the amplifier or receiver and select a source, such  
as the tuner or CD player.

HOTLINE  
• Individual room on/off selector switches  
5. Slowly turn up the amplifier or receiver volume and set it to  
a comfortable (not maximum) listening level. Be careful not  
to overdrive or “clip” your amplifier. If the sound becomes  
muddy or distorted, you have reached the limit of your  
amplifier's volume capability and should quickly reduce the  
volume to avoid damaging your speakers.  
If you have  
• 12-step controls; 54dB maximum attenuation  
questions regarding  
the operation of the  
Niles TVC-1, contact  
your local Niles  
dealer or Niles
