One Used Sonance ASAP3D SE Amplifier. Comes with rack ears. Owners manual. One AC trigger power cord and one power cord. From the manufacturer: The ASAP3D SE combines the latest digital power amplifier technology with proven Sonamp® auto House/Local source switching and BBE® Sound Enhancement in a new small package that dramatically expands your installation options. Featuring a highly efficient ICEpower® digital amplifier that provides 25W RMS/ch @ 8 ohms and 50W RMS/ch @ 4 ohms with very little heat generation, the ASAP3D SE is housed in a 1U high by ½-rack wide package. This allows you to mount the amplifier almost anywhere (a key-hole on the bottom panel even lets you hang it on a wall behind a flat screen TV), improves its long-term reliability and provides significant energy savings over conventional amplifier designs. (ICEpower was developed by B&O, a company known for high-quality sound.) Features: 25W RMS/ch @ 8 ohms; 50watts RMS/ch @ 4 ohms ICEpower® digital amplifier is highly efficient, generating very little heat and keeping the amplifier’s size to a minimum, both of which greatly expand installation options. Small size (1U rack height, ½-rack width); amp is small enough to mount on the wall behind a flat-screen TV. Automatic House/Localsource switching Source switching can be triggered by audio signal, TV power-up, external control voltage or IR signal. IR-controllable (input switching, volume, muting, BBE®). IR Output connections pass signals from IR controller to emitters for controlling 3rd-party devices. IR Bus connection links control signals from multiple ASAP3D SEs to a single set of emitters. BBE® Sound Enhancement with +3dB, +6dB and OFF settings. Front-panel LEDs indicate operating status and fault conditions. Removable quick-connectors and trigger switches simplify installation.
