The DI6
SM
- a Unique Pro Audio
problem solver
DVDs, CDs, Tape/cassette decks, audio for
video, drum machines, synthesizers, bass
guitars, computer audio; at some stage all
these need linking up to Balanced inputs,
whether the application is Live sound, Stu-
dio or Broadcast.
To solve these problems, we've developed
the DI-6
SM
:
Six active D.I. (Direct Injection) boxes,
plus a 6 into 1 Line Mixer,
plus a 1 to 6 Microphone/ Line Splitter
A Pro Audio Toolbox
This unique and flexible audio toolbox al-
lows Six independent unbalanced audio
sources to easily and quietly interface with
Balanced pro audio systems, either to indi-
vidual channels or summed down to one
Master output.
But that's not all. By pressing a single switch
on the rear panel the DI-6
SM
will change
from being Direct Boxes and a Mixer to be-
ing a 6 way Splitter (distribution amplifier).
Now it will split an incoming Microphone or
Line signal to 6 individual outputs or zones.
On the front panel, each channel has two
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, Balanced Mix Out jack, and status
LEDs indicating whether the unit is in DI or
Splitter mode, plus a Phantom Power LED.
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 - and a Micro-
phone Input!
On the rear, each channel has an XLR Bal-
anced output, with associated Ground lift
switch and status LED, to isolate the chas-
sis and electronic grounds.
The Master section has a Balanced XLR
output carrying a Mix of the six channels.
There is also a Balanced XLR input with a
switch to put the unit in either DI or Splitter
mode. This input can be switched to either
a Line Input or a Microphone Input with as-
sociated Gain control and Phantom Power
switch. Next to the Balanced XLR Input there
is a Balanced XLR Microphone Loop Out-
put to continue the Mic or Line signal to
other equipment if required.
All this in a compact 1RU package!
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 stand-
ard 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 the
DI-6
SM
is known as 'The total Audio Patch-
ing System in 1 RU!'

The signal processor shall be a six channel unit in a
steel chassis six inches deep and one rack unit high.
The unit shall be capable of operating in four modes:
firstly, as Six active Direct boxes, secondly, as a 6:1
Line Mixer, thirdly, as a 1:6 Line Splitter, and fourth, as
a 1:6 Microphone Splitter. It shall be capable of oper-
ating concurrently in the first two modes, and there
shall be rear panel switches to facilitate the micro-
phone or line splitter mode. There shall be also be a
master level control, which operates in all modes.
Each channel shall have a High Impedance input and
output jack, a level control from oo through to +15dB,
and an LED to indicate the onset of circuit overload.
Each channel shall have a corresponding electronically
balanced XLR output connector, with audio ground lift
switch and status LED.
On channels 1 to 6, the Hi Z input connector shall have
an Input impedance of 2 Meg Ohms, and the input
headroom shall be +21dB. The frequency response
(all channels and masters) shall be 20 Hz to 20 KHz,
±0.4dB. The Output impedance shall be 600 ohms
balanced, and the maximum Output level shall be
+26dB, with a Signal to Noise ratio at unity of -104dB
A weighted (-98dB unweighted). THD shall be .003%
@ 0dB, 1 KHz, and the unit shall have a dynamic range
of 107dB.
The Master section shall have an Output Signal/Noise
ratio of -96db A weighted, with all inputs and master
@ unity, an output level of +26dB, and THD of .006%
at unity. The master section output connectors shall be
both XLR and TRS jack.
The Splitter input shall be a balanced XLR connector
situated on the rear panel, with a switch to enable this
mode and status LEDs on the front panel. The maxi-
mum Line level to this input shall be +20dB, with an
impedance of 20 K Ohms balanced. The Microphone
