Description of EAAMP12D45A / EA-AMP-12D-45A:
Featuring a chassis thats 50% shorter and significantly lighter than competitive models, this digital amplifier trims the fat while providing the muscle of 45 watts RMS per channel. Perfectly at home in multi-room applications, it features audio sensing turn-on, adjustable gain control, and bridgeable outputs, giving installers the versatility required for today's sophisticated audio systems. Dont be fooled by its size this amplifier has all the performance and features you want, in a compact form factor youve never seen before.
Maximized Power, Minimized Space
How were we able to pack 12 channels of power into a compact 1U of rack space? We started by using a switching power supply thats more efficient, produces less heat, and is smaller and lighter than a transformer-based power supply. Then we fully maximized the back of the amp no square inch was unused to free up space in the rack without sacrificing power or features. Rack ears are included.
Our engineers have combined advanced digital amplifier technologies with installer-friendly features to create a robust power plant built from the ground up for today's multi-channel audio applications. Unlike analog amplifiers from the competition, our digital amplifiers are much more energy efficient and run up to 80% cooler. Combined with a highly efficient power supply, theres no need for oversized heat-sinks, so youll save space with a chassis thats up to 50% smaller.
Three Turn-on Modes
With three turn-on modes its easy to integrate with simple volume controls or sophisticated control systems. Use Audio-Sense for Sonos / Apple Airplay multi-room audio when the last source shuts down, the amplifier goes into a power-saving standby mode. The 12V trigger inputs and outputs allow you to use a preamp or control system to turn the amp on/off or have it "wake up" another device, while Always On provides a go-to solution for bars, restaurants and other high-use spaces.
Note: The front panel power button is inoperative when the 12V Trigger or Audio Sense power modes are selected.
From single source with volume controls (Global) to independent sources at each room (Direct) or any combination in between this amplifier has the flexibility you need. Global A/B provides two independent global sources that can be mapped to desired channel pairs perfect for creating two different zones that each play a different kind of music.
Bridgeable Speaker Outputs
For larger speakers or high-power applications, bridgeable channels allow you to combine any two channels into a single 90W channel. For example, run two "standard" zones of audio plus one high power zone. Or use this amplifier as the ultimate bi-amping solution for two-channel applications with four bridged channels!
Note: 8-ohm minimum load required when using bridge mode.
The EA-AMP-12D-45A offers gain adjustments for each channel pair, allowing you to independently trim output levels in each zone whether using the global or line level inputs. In volume control-based systems, these may be used to prevent harmful clipping that could cause damage to the amplifier or speakers.
Built-In ESD and Surge Protection
Multi-room AV environments can be tough on an amplifier. Each speaker run acts like an antenna, so all kinds of nasty things can happen when the weather changes. Thats why we engineered this amp with surge protection components that exceed CE Level 3 standards. During development, every connection was tortured using both an ESD and lightning simulator all speaker outputs, RCA connectors even the power input have been surged ESD tested with up to 15,000V and Surge tested at 2,400V. Most importantly, though, they each lived to tell about it.
Creating Common Ground
If youve ever experienced hum from your speakers or noise on your TV, odds are it was due to system grounding. This amplifier was engineered for not only the best surge protection but also with an isolated common ground for the audio circuits. The result is a great sounding, and reliable system that your customer will enjoy for years.
