Russound R1250MC Installation Manual
Introduction
The Russound R1250MC is a 12-channel power ampli er and is ideal for use
as the main ampli er in home theater and distributed audio systems. The 12
channels are arranged in pairs to provide ampli cation for six stereo zones. The
R1250MC provides an array of useful features such as bridge mode operation,
independent zone triggering, bus inputs and multiple speaker outputs per
zone to meet a wide variety of applications and con gurations.
The R1250MC is rated at 50 watts per channel into 8 ohms and 80 watts
per channel into 4 ohms. With the Stereo/Bridge Mono switch in the Bridged
Mono position, both channels in the zone are combined for a higher powered
mono output. In bridged mode, the R1250MC is rated at 140 watts of power
into a single 8 ohm load. All this power is backed by three high output torodial
transformers. Each ampli er output channel incorporates robust protection
circuitry for safety and reliability under extreme circumstances.
Thermal Protection
All Russound ampli ers are designed with special circuitry to safeguard the
ampli er under a thermal overload condition. Thermal protection mode can
only engage when the unit has been run at high volume for extended periods
of time without adequate ventilation and/or when speaker impedances are
below the minimum levels for the ampli er. If this fault occurs, turn o the
ampli er, and check that the speaker impedance rating is above the minimum
rating. Also check for adequate ventilation around the ampli er and make
adjustments if necessary.
Once the unit has cooled to safe operating temperatures, the ampli er may
be powered back on.
Protection Circuitry
All Russound ampli ers are designed with special circuitry to safeguard the
ampli er under a short-circuit condition. A faulty speaker can also cause a short
circuit condition. The front panel LED illuminates orange when the ampli er is
in short circuit protection. If this fault condition occurs, turn o the ampli er
and check speakers for short circuit conditions when appropriate.
PRODUCT OVERVIEW
Rack Mounting
The R1250MC ampli er can be rack mounted using the included rack-mount
ears and hardware to attach the ears to the ampli er. The ampli er will take
three rack spaces with the feet removed.
