BSS AR-416 4-Channel Active Direct Box
For nearly 25 years, BSS have been manufacturing professional audio products that combine the highest levels of performance with technical excellence and proven reliability. All of this expertise and experience is encapsulated in the AR-416 4-CHANNEL ACTIVE DI. No recording session or touring stage is complete these days without a liberal sprinkling of DI boxes and similar interfaces numbering in their dozens, Stereo and multi-channel samplers, MIDI voice modules, drum machines and sequencers, now form a major part of the composite sound mix along with the increasing numbers of acoustic instruments fitted with sophisticated electronic "bug" pickups. All these demand large numbers of high quality active DI channels, which until now meant a tiresome dependence on batteries or phantom power. Bringing the direct injection process firmly up to date, BSS have created the practical solution in simple but versatile form - the AR-416 4-CHANNEL ACTIVE DI.
Features:
- High impedance 1Mohm, 1/4" instrument jack per channel with both parallel and buffered Link outputs on 1/4" jacks to feed backline amps and/or local sub mixers.
- Low impedance professional XLR outputs, active buffered, transformer balanced and floating, capable of driving down to 600 ohms over long cable runs.
- Selectable 8KHz Lo-pass filter, polarity reverse and earth lift functions on "XLR-side."
- 3-way selectable input attenuator (0dB, 20dB, 40dB PAD) and another earth-lift switch on "jack-side." The two earth-lifts per channel have interactive LED indicators to show true status to avoid confusion.
- Total ground isolation with no significant crosstalk between channels and very low noise floor.
- Operational and performance criteria modelled on proven standards set by the much acclaimed AR-116 Active DI Box from BSS
