About the BSX16

The NEW ARX BSX16 Active Microphone/Line Splitter has been developed to deliver the performance required by the increasingly sophisticated level of today?s standards of E.N.G and broadcast audio production.

16 Output splits
The BSX16 is a single channel 16 way active press/broadcast splitter with transformer balanced and isolated Output Splits. Although a single channel unit, there are Dual inputs with individual Gain and Level controls, for use when using lecterns with dual microphones. Dual Loop Outputs are available to connect the BSX16 to additional units, or for the dual inputs to continue on to a mixing console. An additional XLR PA Output connector is available on the rear panel for basic system connection.

Numbered marker panels above or below each split provide a space where individual connections can be noted.

Splits 1?8 are at Line level, and splits 9?16 are switchable mic or line level. There is a ?20 dB input Pad switch, plus silently switchable 48V Phantom power, LED metering (?40dB, 0dB and +6dB) and a separate Pre-Fade headphone level control and socket, for signal monitoring.

Internally, powerful RF input filtering removes both common mode and differential interference at ultrasonic frequencies and above. High CMRR is achieved by the use of precision components throughout.
The BSX16?s internal transformer based power supply is double shielded to get the maximum benefit from the ultra low noise design of the circuitry.

To sum up, this feature packed two RU device is the answer wherever multiple transformer output splits from up to 2 input signals are required. The ultra low noise design and intuitive, 'user friendly' layout of the BSX16 provide flawless audio performance in any professional application. 

Every BSX16 is hand soldered, with a 48 hour burn in followed by a 100% re-test and visual PCB QC check prior to shipping.
