The ARX BSX-16 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.

The BSX-16 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 BSX-16 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 BSX-16’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 BSX-16 provide flawless audio performance in any professional application.

MSX 32:  8 in, 32 Out Active Microphone Splitter / Line Splitter
MSX32 Microphone Line Splitter

  • Eight channel / four way split per channel
  • Channels linkable up to 1 in, 32 out
  • Ultra low noise design
  • 'SilentSwitch' Phantom Power switching
  • –20 dB pad switch
  • 0 to +40 dB Gain available via rear switches
  • Headphone monitoring and PFL metering
  • Electronically Balanced Inputs, Transformer Balanced A & B Outputs (standard)
  • Transformer balanced Outputs option for Main and Monitor Outputs
  • Intuitive, 'user friendly' layout
  • Flawless audio performance
  • Optional Redundant PSU 32 Power Supply for "must Run" Applications
Superb Audio Quality
Active microphone and line signal splitting has a number of benefits over using passive splitters: primarily these are improved sound quality, noise figures comparable to the best microphone inputs, and increased resistance to RFI.

About the MSX 32
With these benefits in mind, the NEW ARX MSX 32 Active Microphone / Line Splitter has been developed to deliver the performance required by the increasing complexity of today’s standards of audio production.

The MSX 32 consists of eight channels of actively buffered ultra low noise Microphone/Line Splitter. Each of these channels has two transformer Balanced splits on the front panel and two electronically Balanced outputs on the rear panel for Main and Monitor. These can be optionally transformer Balanced (Model MSX32 T/ALL).

Each channel has a –20 dB pad switch plus silently switchable 48V Phantom power with indicator LED. A PFL switch and 6 LED metering enables each channel to be easily checked with headphones for signal monitoring, and also for line tracing when troubleshooting.

Gain through the MSX 32 can be set individually by the small DIP switches on the rear of each channel, from 0dB through to +40 dB in 10 dB steps A ‘Link’ switch links each channel to the previous one, providing an ultimate maximum of 32 Outputs from a single input. An indicator LED shows when this is active. A Clip LED indicates imminent signal overload through the channel, and a numbered marker panel on the front provides a space where individual channel connections can be noted. Number stickers are provided to give each channel an individual number for up to 40 channels when multiple MSX32’s are being used.

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. Advanced user options include internally jumper linking Inputs to Main outputs, and Ground lifting Output Pins 1 as required.

Internal Power Supply and the PSU32 Redundant back-up supply


The MSX 32 uses an internal toroidal transformer based power to get the maximum benefit from the ultra low noise design of the splitter circuitry.

However, for “critical” applications where systems must keep operating, we recommend including the PSU 32 redundant power supply unit. Individual +V, -V and 48VDC rail LED indicators show when the PSU 32 redundant power supply unit is connected to the MSX 32.

An illuminated power switch on the front panel provides visual confirmation of AC power connection to the unit.
The headphone output and the 6 LED PFL metering are both mounted on the right hand side of the front panel. Rear panel connectors enable this function to be linked when using multiple MSX 32 units..

To sum up, this feature packed two rack unit device is the answer wherever transparent signal buffering and routing is required.

MaxiSPLIT:  2 into 4, 1 into 8 Line Distribution Splitter


In the modern multi-zone Installation audio environment it has become a fact of life that one signal now has to go to more than one place, and usually at differing levels. And, to ensure a low noise floor and good frequency response, the split signal needs to be buffered and balanced as well.

The Solution
To fulfill this seemingly simple but important signal splitting task, ARX have designed the MaxiSPLIT: - two independent channels of 1 into 4 Splitters, switchable to a single channel 1 into 8 Splitter by using the rear panel channel link switch. Mode status is shown by the front panel LED indicators.

Balanced Inputs and Outputs
Each channel features Male and Female electronically balanced XLR inputs, with passive RF filtering to prevent RF breakthrough. Each output features an electronically balanced Male XLR output with individual output gain control on the front panel, providing up to +6dB of gain.

Wide Dynamic Range
Internally, careful attention to signal path design has resulted in a unit with wide dynamic range, enough headroom to cope with the hottest line signal, and better than digital noise specifications.

Universal AC Power
AC power range is a universal 100 to 120V or 220 to 240V AC, and is connected to the unit via a standard IEC connector, with built-in fuse and voltage change switch

Applications
A typical MaxiSplit application would be as a Master Line Distribution Splitter. In this way it can control the levels of 4 different zones in a stereo installation, or up to 8 different zones in a mono installation.

Other applications include splitting effects sends to multiple effects units in both Studio and Live sound applications, supplying different feeds from the main signal, and separating OB signals in broadcasting.

Accurate and compact, the MaxiSplit's unique combination of ultra low distortion, low noise and high headroom makes it the ideal installation line distribution splitter.
