Introduction
Thank you for choosing this
ARX DI-6SM
. We hope you enjoy using this unique product as
much as we enjoyed creating it. As with all ARX equipment, it has undergone extensive
factory testing and ‘burn in’ before shipping. To ensure continued trouble free use, please
familiarise yourself with the contents of this manual before using.
About the DI-6
SM
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.
Most consumer oriented audio products have unbalanced outputs, whereas Balanced Low
Impedance (Low Z) is the norm in pro audio. CDs, DVDs, Tape/cassette decks, Video audio,
drum machines, synthesizers, guitars, computers; at some stage all these need linking up to
balanced inputs, whether the application is Live sound, Studio or Broadcast.
Recognising this fact, ARX have developed the
DI-6SM
- Six active D.I. (Direct Injection)
units, plus a 6 into 1 Line Mixer, plus a 1 into 6 Mic or Line Splitter, and all in a compact one
rack unit package!
This unique and flexible audio problem solver allows Six independent unbalanced audio
sources (keyboards, instruments, tape decks etc.) to easily and quietly interface with balanced
pro audio systems; to individual channels or summed down to one Master output, or will split a
single incoming Mic or Line signal to 6 Outputs.
Despite the compact size of the
DI-6SM
, it’s not short of features. Each channel has 2 phone
jack IN/OUT sockets, level control from infinity (off) through 0 dB to + 15 dB gain, plus a
clipping 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, there is a numbered marker panel you can write on for easy confirmation of
channel assigns.
On the rear, each channel has an XLR Balanced Output, Ground lift switch and indicator LED.
The Master section has both balanced XLR and Jack outputs. In addition there is an XLR
Balanced Input and switch to put the unit in either DI or Splitter mode.
Splitter
The Splitter function available on the
DI-6SM
enables a single Microphone or Line Input signal
to be split to up to 6 Outputs. The level of each Output is controlled individually by the front
panel Gain controls, with the Master Level control acting as an overall level setter.
To get into Splitter mode on the
DI-6SM
, first turn down all level controls on the front panel,
then select Splitter on the rear panel switch, then Mic or Line, and plug a lead into the
Balanced XLR Splitter Input on the rear panel. An LED will light up on the front panel to
indicate Splitter mode. The tick mark on the Input Gain control indicates a typical microphone
gain setting. Bring up the Master level control first, then each individual level control until you
have the levels you require. If the Signal needs to continue on to another piece of equipment,
connect a lead from The Loop Output XLR connector adjacent to the Splitter Input.
Phantom power for condenser microphones is available by pressing the Phantom Power
switch on the rear.
!!! TURN DOWN THE MASTER MIX LEVEL CONTROL BEFORE SWITCHING PHANTOM
POWER ON !!!
The
DI-6SM
is also ideal as a -10 dB to +4 dB level matcher for consumer audio products,
home studio equipment, and Video Audio in discos and clubs.
In Radio and TV broadcast work the
DI-6SM
is a must in any remote truck, OB van or mixing
suite, being easily and quietly able to deliver the +8 dB or greater line levels that are common
to the industry. It will do this in Direct Injection mode, Line mixer mode or Splitter mode.
In short, the
ARX DI-6SM
is a truly unique audio problem solver for all facets of the audio
industry, from Broadcast and Studio work through to Discos, Clubs and Concert sound.
Being AC mains powered the DI-6SM has no batteries to go flat, nor does it require Phantom
Power. However, many mixing consoles have Phantom Power available to all channels or
none, or to blocks of channels. If this is the case, then the DI-6SM will quite happily accept
Phantom Power.
Special Note
Just two things the DI-6SM won’t do:
Apart from the Input to the Splitter function, the DI-6SM is a Line Mixer, so it won’t accept
Microphone level signals into the front unbalanced inputs, and...
It won’t accept speaker lines, so don’t plug the output of an amplifier into it.
