Introduction
The Russound TVA2.1 is a 2-channel low-profile amplifier, designed to be used
to bring Better Sound for TV by allowing a high quality, easy-to-use, easy-to-
install amplifier to be added to any television installation.
Its thin footprint means the TVA2.1 can be hidden behind the television or
mounted in an in-wall panel behind a television for convenience. The built-
in IR learning function allows for ANY typical remote control to be used and
eliminates the need for an external control system. This can dramatically
reduce the cost of adding additional rooms of audio to a home and keeps the
operation simple and intuitive for the homeowner by letting them use their
current remote control device.
The 2 channels of amplification are available for up to two pairs of 8-ohm
speakers, while also offering a connection for a subwoofer to enhance a room's
sound.
The TVA2.1 provides an array of useful features, such as IR Learning, use of a
high quality low-profile external IR sensor, an LED Power Light that can be
toggled on and off, as well as a low-profile chassis design.
The high quality class-D digital amplifier sends a respectable 30 Watts per
channel of power into 8 ohms. There is a line level subwoofer output to support
2.1 Audio, making the TVA2.1 an easy solution for improving the audio quality
in any room with enhanced bass response.
The TVA2.1 features three input options for flexibility. A traditional analog
RCA line level input, and both Digital Coax and Optical S/PDIF. The TVA2.1 also
supports 24bit/96khz digital audio in a PCM stereo format.
Product Features
• Class-D amplifier 2 x 30W RMS into 8 ohm
• 24-bit/96kHz S/PDIF support
• S/PDIF, optical and analog line level inputs
• 4-pole speaker detachable screw connector and line level RCA subwoofer
output
• IR Learning for basic volume control.
• Small footprint with mounting options for discreet installation
• External 24v power supply
Thermal Protection
All Russound amplifiers are designed with special circuitry to safeguard the
amplifier 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 amplifier. If this fault occurs, turn
off the amplifier, and check that the speaker impedance rating is above the
minimum rating. Also check for adequate ventilation around the amplifier and
make adjustments if necessary. Once the unit has cooled to safe operating
temperatures, the amplifier may be powered back on.

Protection Circuitry

All Russound amplifiers are designed with special circuitry to safeguard the
amplifier under a short-circuit condition. A faulty speaker can also cause a
short circuit condition. The front panel LED illuminates orange when the
amplifier is in short circuit protection. If this fault condition occurs, turn off the
amplifier and check speakers for short circuit conditions when appropriate.
Mounting
The mounting wings on the sides of the TVA2.1 can be used for various
mounting options:
1. Mounting into a structured wiring type behind-the-tv box. The width of
the TVA2.1 does not allow 6" on-center holes, but the TVA2.1 can be secured
on either side and a simple Zip Tie can be used for securing the amplifier in
any location within the structured wiring box.
2. Mounting to the rear of a TV using any 3rd party VESA type mounting
panel, or simply by attaching it to a TV mount. The thin form factor allows
it to fit on many tilt or pivot type mounts. In this type of installation, it is
recommended to disable the Power LED light so that it does not bother the
end user.
3. Wall Mounting (screws not included) – The installer can easily mount the
TVA2.1 to a wall or cabinet.
