AV-1800 2 x 50w Digital Amplifier 2 x 50w RMS (at 8 ohms) low impedance digital power amplifier3 x Stereo inputs / 1 x Stereo Pre-Output / 1 x Balanced Mic input with Phantom Power Bluetooth Input IR remote included, RS-232 control Details The improved AV-1800 is compact, and has a simple interface with just two dials which are turned to adjust and pushed to switch. It has a selection of inputs - including Bluetooth and a microphone input, making it suitable for meeting rooms, small auditoriums, lecture theatres, school halls, and small churches. BluetoothThe amplifier can automatically switch to the Bluetooth source when it is paired. Bluetooth can be renamed and the pin changed by connecting to a PC (see software link below). Microphone InputIt uses a professional XLR connector and the input is balanced to eliminate electro-magnetic noise induced on long cables. The microphone input has Phantom Power - a voltage which is required by condenser-type microphones such as lectern microphones. RS-232It can be controlled by a control device such asTechconnect Control via IR or RS-232. It also comes withan IR remote control gives the user bass and treble adjustment and direct input selection. D-ClassAn efficient Digital-class amplifier chip dramatically reduces power consumption especially at rest. 3 x Stereo InputsThree stereo inputs accept input from a variety of sources such as computers (via the headphone jack), tablets or phones.2 of the inputs are via 2-phono (RCA) connectors on the rear panel. Input3 is via a 3.5mm Minijack connector, and is duplicated on the front and rear panels for easy access. Line OutputA line-level pre-output on the rear panel bypasses the internal amplifier. It would connect to a larger amplifier or powered loudspeakers. It is post-mix, which means any volume adjustment made on the front panel affects the output level. Auto-StandbyIf the amplifier senses no input it will automatically go into standby mode. When it senses input it will reactivate. Auto-standby can be disabled. Mounting OptionsOptional mounting hardware is included to allowcable-tying either to a projector ceiling pole, or into a rack.
