Introduction
The OpenHouse H572 Stereo Volume Control w/
Override is a twelve-step stereo Volume Control with
Variable Impedance Match settings. The H571 is a mono
Volume control w/ Override conforming to the same
specifications (except stereo capability). This Volume
Control was designed to connect speakers to amplifiers
with power ratings up to 75 Watts peak music power.
Based on proven technology, the H571/H572 provide a
perfect solution when using multiple speakers in high
powered multi-room applications or when basic volume
functions are needed with a receiver or amplifier. This
device was specifically designed to be compatible with
the OpenHouse H560 Music & Communications
Distribution Center and will work with other amplifiers, as
well.

Rough-In
The H571/H572 will fit into the majority of single-gang
boxes and P-rings. If local building codes allow,
P-rings provide easier installation due to the greater
mounting depth that can be obtained. This Volume
Control should not be mounted in the same rough-in box
as 110 volt devices--this can cause undesirable noise in
the speakers. High-wattage light dimmers can also
cause noise issues.
Wiring
Wiring for the H571/H572 consists of speaker wire and
CAT5 when connecting to the H560. The H571/H572 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. In-wall runs should utilize twisted pair
wiring. Please consult local building codes before
attempting in-wall wire runs.
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 WIRING BEFORE CUTTING DRYWALL

1. With an Ohmmeter, measure the resistance between
the + and - of each pair of wires that is to be con-
nected to the amplifier's speaker outputs. Under no
circumstances should this reading be below 4 Ohms.
A reading of less than 4 Ohms may mean that the
Input and Output plugs on the Volume Control may
have been hooked up backwards (potentially causing
damage to the amplifier). An open reading may indi-
cate a polarity reversal.
2. Make sure amplifier is not powered up when making
connections or testing.
Operation
Once the H571/H572 is connected to both amplifier and
speakers, adjustment and testing can occur. When using
a receiver or integrated amplifier with it's own Volume
functions, turn the Volume all the way down. Turn Volume
all the way up on the H571/H572, then slowly adjust the
Volume on the receiver untill a comfortable listening level
is obtained. Leave the receiver's Volume at that level
and adjust Volume from the H571/H572. When connect-
ed directly to an amplifier, follow the above procedures,
but adjust the amplifier's Gain Control rather than the
Volume knob of a receiver. Once the gain has been
established, no further adjustment should be necessary.
