Digital Amplifier, 2 x 100w @ 8 ohms, 4 x Stereo inputs, 1 x Microphone inputs, 20Hz~20kHz
The Techaudio AV-1700+ has the same features as Vision’s AV-1700 but has an increased power output. The AV-1700+ is compact, flexible, easy to use and is extremely efficient. It has a selection of inputs – including a microphone input – which make it suitable for meeting rooms, auditoriums, lecture theatres, school halls, and small churches.
<b>Microphone Input</b>
It 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.
<b>RS-232</b>
It can be controlled by a control device such as Techconnect Control via IR or RS-232. It also comes with an IR remote control gives the user bass and treble adjustment and direct input selection.
<b>D-Class</b>
It uses an efficient Digital-class amplifier chip which dramatically reduces power consumption especially at rest.
<b>4 x Stereo Inputs</b>
4 stereo inputs accept input from a variety of sources such as computers (via the headphone jack), tablets or phones. 3 of the inputs are via 2-phono (RCA) connectors on the rear panel. Input 4 is via a 3.5mm minijack connector, and is duplicated on the front and rear panels for easy access.
<b>Line Output</b>
A 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.
<b>Simple Interface</b>
The clear simple interface offers the user just two dials which are turned to adjust and pushed to switch.
<b>Auto-Standby</b>
If the amplifier senses no input it will automatically go into standby mode. As soon as you press play on your source device it will automatically switch on again.
<b>Mounting Options</b>
Optional mounting hardware is available which allows attachment to a wall, or projector ceiling pole.
