The A2100 Digital Amplifier is designed to add high quality, high powered stereo amplification to any audio system. Ideal for adding extra power wherever needed or for adding additional speakers as needed, it is the perfect choice for larger rooms or outdoor zones. The space-saving design allows for an easy fit in any equipment rack and the installer-friendly integration features allow it to blend seamlessly into a system and activate automatically with other devices as needed.
High Quality Digital Amplification
By utilizing the latest Class D digital amplification technology, the A2100 offers an impressive 100 watts per channel at 8=ohms with less than 0.1% Total Harmonic Distortion (THD+N).
Half-Rack Size
The benefit of a modern digital amplification system is that the A2100 takes up a half-rack space and is only 1U high. Each A2100 includes a complete rack-mounting kit in the box to mount either a single A2100 or to link two Russound half-rack components together into a single 1U rack space.
4-ohm Stable Design
Don’t let the small size fool you. Designed to handle an impedance as low as 4 ohms allows a total of four 8-ohm speakers to be used with the A2100 amplifier.
Bridgeable to 225 Watts
If 100 watts isn’t enough for you, the A2100 includes a bridge option that allows you to bridge both channels into a single incredibly powerful 225-watt output. Combine two A2100 units together in the same system and you can have a stereo output at 225-watts per channel at 8 ohms, all in a 1U design.
Buffered Line Outs
The A2100 includes a stereo buffered line output that can be used for daisy-chaining additional amplifiers to your system. By using the integrated line outputs, you can add multiple amplifiers and create an expansive audio zone for very large rooms or outdoor zones that require additional power or more speakers.
System Integration Features
The A2100 has all of the features needed to integrate fully with any other audio components. It has three modes of operation:
Always On – Ready whenever you need it in your system
Auto On (Signal Sensing) – Detects the presence of an audio signal and turns on when needed
Trigger – Detects the presence of a 12vDC signal and turns on the amplifier when the signal is present and turns it off when the signal goes away.
Removable Screw-down Connectors
Installer-friendly connectors are used for all speaker connections, allowing audio professionals to lock in all connections for a long-lasting, trouble-free installation that is still easy to service and adjust throughout the life of the system. All connectors accept up to 12ga wire.
Worldwide Power Supply
Designed for worldwide operation, the automatic internal switching power supply can handle any voltage from 100v to 240v at 50/60Hz. The A2100 is available in two versions, one with a US power cord included, and an international version, the A2100i, which includes the three most popular international power cords: Euro, UK, and Australian.
Cord lock
The rear panel of the A2100 includes a removable cord lock that can be used to secure the power cord to prevent accidental disconnects when servicing the system, moving wires, or pivoting a rack full of gear. No more frustrating service calls for a simple unplugged unit.
Flexible Mounting Options
While easy to rack mount, the A2100 also includes the option of using the rack ears to mount it to a wall or other flat surface like the interior of a cabinet. The elegant design also permits its use in a table-top application for use on a shelf or cabinet.
