ARX DI6s 6CH. ACTIVE DIRECT BOX.SPLITTER and LINE MIXER

About the DI6s
It's a fact of audio life that a lot of equipment that has to be connected to
professional audio systems isn't impedance or level compatible.
Interfaces Unlimited
Tape/cassette/DVD/CD decks, audio for video, drum machines, synthesizers,
bass guitars, computers; at some stage all these need linking up to Balanced
inputs, whether the application is Live sound, Studio or Broadcast.
To solve these problems, we've developed the DI-6s:

Six active D.I. (Direct Injection) boxes,
plus a 6 into 1 Line Mixer,
plus a 1 to 6 Splitter,
All of this in a compact, all steel 1 RU package.

A Pro Audio Toolbox
This unique and flexible audio toolbox allows Six independent unbalanced
audio sources to easily and quietly interface with Balanced pro audio systems,
either to individual channels or summed down to one Master output.
But that's not all. By pressing a single switch on the rear panel the DI6s will
change from being Direct Boxes and a Mixer to being a 6 way Splitter (line
distribution amplifier). Now it will split an incoming signal to 6 individual outputs
or zones.
On the front panel, each channel has 2 IN/OUT jacks, a level control from infinity
(off) through 0dB to +15dB gain, and a Clip indicator LED.The Master section has
a Master volume control and status LEDs indicating whether the unit is in DI or
Splitter mode. In addition, as on all ARX single rack unit equipment, each channel
has a numbered marker panel ('scribble strip') you can write on for easy confirmation
of channel assigns.
Balanced Outputs
On the rear, each channel has an XLR Balanced output, with associated Ground lift
switch and status LED, to isolate the chassis and electronic grounds.
The Master section has both Balanced XLR and Unbalanced Jack outputs. In addition
there is a Balanced XLR input with a switch to put the unit in either DI or Splitter mode.
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 removable power lead and standard 3 pin IEC connector, with built-in fuse and
voltage change switch.
With so many handy functions, plus a true 'user friendly' layout, it's no wonder people call
the DI-6s 'A total Audio Patching System in 1 RU!'
You'll never compromise on Quality when you choose ARX

Practical distributor with 1 input and 6 outputs

• Extends every mixer with additional outputs
• 1 stereo XLR input
• 6 stereo zone outputs (XLR)
• Each zone with level control and mono switch
• LED display of signal input and mono/stereo mode
• Rack installation with 1 U
• (19") 48.3 cm rack installation 1 U

Signal distributor. 1 stereo input / 4 stereo outputs or 1 mono input / 8 mono outputs

This audio distributor is very useful to supply several audio devices with only one audio source. Its 2 operating modes allow to work with mono or stereo signals. Output level can be controlled independently.

WD 421 adapts itself to work with different impedances, ensuring that output signal level is at least equal to input signal level. It avoids any undesired attenuation and features a LED vumeter to visualize the input signal level.

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 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 four electronically Balanced
splits ? two outputs on the rear panel for Main and Monitor, plus two more output
splits on the front panel. All splits have the option of transformer balancing if so
specified.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 stepsA ?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 MSX32s 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
The MSX 32?s internal toroidal transformer based power supply is triple shielded to
get the maximum benefit from the ultra low noise design of the splitter circuitry.
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 RU device is the answer wherever transparent
signal buffering and routing is required.
