Digital Amplifier, Pair 3-Way Wall Loudspeakers, 2 x 100w @ 8 ohms, 4 x Stereo inputs, 1 x Microphone inputs, 20Hz~20kHz

Manufacturer : Vision


Availability: In stock


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.

Microphone Input
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.

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.

It uses an efficient Digital-class amplifier chip which dramatically reduces power consumption especially at rest.

4 x Stereo Inputs
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.

Line Output
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.

Simple Interface
The clear simple interface offers the user just two dials which are turned to adjust and pushed to switch.

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.

Mounting Options
Optional mounting hardware is available which allows attachment to a wall, or projector ceiling pole.

Vision’s SP-1800 professional wall mounted loudspeakers are super-easy to install, look beautiful, and produce rich and powerful sound.

They are 240mm tall and use a 5.25 inch woofer – the most popular size for classroom, meeting room, and boardroom applications.

These loudspeakers use three drivers; a woofer, a squawker, and a tweeter. Asking a driver to produce a wide range of frequencies is always a compromise, so dividing the sonic range into three means each driver has a narrower range of frequencies to produce, resulting in less distortion and clearer sound.

Bass Reflex
A bass reflex port allows greater excursion of the woofer, allowing the woofer to produce lower frequencies, and the phase-delayed movement of air from behind the woofer to the front reinforces the bass even more.

Rugged Grille
A metal grille protects the drivers from physical interference.

Tough Finish
Constructed with tough ABS plastic, the finish withstands the rigors of the professional use.

Pro AV Applications
In small to medium presentation environments a wide dispersion is generally more important than microphone feedback management, so no horns are used.

Horizontal C bracket
The adjustable brackets allow the installer to easily angle up 30º or down 30º. Or leave the brackets off and use as shelf speakers.

Note: these are passive loudspeakers – there is no amplifier built in – so they need to be used with an external amplifier.
