INSTALLATION MANUAL
Introduction
The ELAN VSOS High Power Stereo Volume Control w/
Override is a twelve-step stereo Volume Control with Variable
Impedance Match settings. The VMOS is a High Power mono
Volume control w/ Override conforming to the same specifica-
tions (except stereo capability). This Volume Control is designed
to connect speakers to amplifiers with power ratings up to 100
Watts RMS. Based on proven technology, the VSOS/VMOS
provides a perfect solution when using multiple speakers in high
powered multi-room applications or when basic volume func-
tions are needed with a receiver or amplifier.
Features
• High Power 100 Watts RMS Per Channel
• 1X/2X/4X/8X VSOS
• 2X/4X/8X/16X VMOS
• ELAN’s Patented Volume Control Override
• Limited Lifetime Warranty
• Twelve-Position Volume Steps
• Decora®Styling
• ELAN Quality
• PTC-Thermal Protection Circuit: When the PTC detects
problems such as, too much power crossed speaker wiring, or
improper impedance, the circuit will open, protecting the volume
control. When the problem has been corrected, the circuit will
close and resume operation.

Rough-In
The VSOS/VMOS will fit into the majority of single-gang boxes.
This Volume Control should not be mounted in the same rough-
in box as primary or mains volt devices, i.e. 110v, 240v--this can
cause undesirable noise in the speakers. High-wattage light
dimmers can also cause noise issues.
ALWAYS CHECK LOCAL BUILDING AND
FIRE CODES FOR LOW-VOLTAGE
DEVICE INSTALLATION AND WIRING
REQUIREMENTS.
IN RETROFIT APPLICATIONS, ALWAYS
CHECK FOR OBSTRUCTIONS SUCH AS
PIPES, CONDUIT, OR ELECTRICAL WIR-
ING BEFORE CUTTING DRYWALL.

INSTALLATION MANUAL
Wiring
Wiring for the VSOS/VMOS consists of speaker wire and CAT5
(if using an ELAN Communications device such as a COM2 or
MAC24). The VSOS/VMOS can accommodate from 14 to 24
gauge speaker wire. Typical installations will use 16 or 18 gauge
stranded copper wire, while longer runs (greater than 80 feet)
should use 14 gauge wires. CAT5 cable should be used for
systems using ELAN’s Volume Control Override features. In-wall
runs should utilize twisted pair wiring. Please consult local build-
ing codes before attempting in-wall wire runs.
DO NOT REVERSE THE AMPLIFIER IN-
PUT AND SPEAKER OUTPUT CONNEC-
TIONS! THIS CAN RESULT IN DAMAGE
TO EQUIPMENT AND/OR PROPERTY.

INSTALLATION MANUAL
Impedance Match Settings
Switch settings on the VSOS/VMOS determine the Impedance
Match settings. See diagram for position of Override Jumpers.
Switch position depends on three things:
1. The minimum impedance rating of the amplifier being
used.
2. The number of speakers being connected to the
amplifier channel.
3. The nominal impedance of the speakers being utilized.
Once the above information has been determined, use the fol-
lowing equations to determine the correct Impedance Match set-
ting for each specific application. Two equations are necessary:
Impedance Rating of Speakers
# of Speakers Connected to Amp Channel
Minimum Impedance Rating of Amp
System Impedance
= System
Impedance
= Impedance Match
Switch Setting
8 Ohm Speaker
4 Speakers = 2 Ohm System Impedance
8 Ohm Stable Amp
2 Ohm System Impedance = 4 X Switch

Impedance Match Switches
Most speakers are rated at 4, 6, or 8 ohms. If connecting
speakers of different impedances to an amplifier, an average
impedance must be determined; i.e. one pair of 4 ohm speakers
is the equivalent of 2 pair of 8 ohm speakers. All 6 ohm speak-
ers should be entered into the equation as 4 ohm speakers. All
volume controls connected to an amplifier channel should have
the same Impedance Match setting.

Never create settings that cause the amplifier to see an imped-
ance below its minimum impedance rating as this can cause
damage to the amplifier.

Page & Doorbell Level Adjustment
When utilizing ELAN’s Page and Doorbell features, it will be
necessary to adjust the Page & Doorbell Volume level. Locate
the Page & Doorbell Volume jumpers as shown on the diagram
below. Each jumper MUST be set to the same position or dam-
age to the unit could occur. Test the Page and Doorbell functions
and monitor the audio levels. Adjust shunts higher to increase
Page & Doorbell volume, adjust lower to reduce volume.
