DI-6SM Application Notes
Setting up your DI-6
SM is very straightforward. It will accept virtually all High
Impedance (Hi Z) and Low Impedance (Lo Z) Unbalanced lines and convert them to Electronically Balanced Low Impedance (Lo Z) lines, suitable for all professional audio applications. Simply choose a channel on the front, and turn the Gain control hard Left. Plug your line into the Input, and your XLR lead into the corresponding Output on the rear. Turn the channel Gain control up until the required output level is reached. 0dB or Unity Gain is marked on the Gain control at approximately 1 o’clock.
To reduce the signal level, turn to the Left; to increase it turn to the Right, up to a maximum of +15dB. The Clip LED will light up if any part of the circuitry is being overloaded. If this occurs, reduce the Input level until it stops. Use the audio Earth/
• Microphone or Line Input select
• XLR Balanced Input for Splitter mode. Pin 2 + Hot, Pin 3 - Cold, Pin 1 Ground
• Mic/Line Loop Output
• Mic/Line Splitter Input Gain
• Phantom Power Switch
• IEC connector witchable 100/110 or 220/240V AC, with integral fuse. Replace with

Ground lift switch next to each Output to eliminate Ground loop hum if necessary. If the Input signal needs to continue on to a musician’s individual amplifier, for
example Bass or Keyboards, insert a lead into the channel Output on the front panel and run it to the amp.
The DI-6
SM also has a Mix function. This is especially useful for today’s multiple
keyboards, drum machine, music computer set ups. Up to 6 individual components can be plugged into the DI-6
SM, and individual balanced lines can be run down to
the main console. A summed mix of these can be sent out to either the monitor console via the Master Balanced Output, or to the musician’s personal amp via the Master Unbalanced Output, or both if you wish.
However if you are running short of channels to the main console, this summed mix

5
can be sent to the main console and the musician can balance the mix to their own taste.
A further advantage of the DI-6
SM for multi keyboard use is that the whole stage
setup can be used unchanged at rehearsal or in the studio. The Splitter function available on the DI-6
SM 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-6
SM, 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-6
SM 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-6
SM 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-6
SM 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-6
SM 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-6
SM will
quite happily accept Phantom Power.
Special Note
Just two things the DI-6 Apart from the Input to the Splitter function, the DI-6
SM won’t do:
SM 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.
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-6SM
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.
