DI-6SM Application Notes
Setting up your DI-6SM 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 approxi-
mately 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/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-6SM 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-6SM, 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 can be
sent to the main console and the musician can balance the mix to their own taste.
A further advantage of the DI-6SM for multi keyboard use is that the whole stage setup can be
used unchanged at rehearsal or in the studio.
