OVERVIE
The Glensound Signature Series DDA1:6 is a professional audio distribution amplifier. It is
manufactured using high quality components and low noise audio circuits to provide many
years of trouble free use.
Although traditionally a broadcast manufacturer Glensound’s products are equally at home
in professional and high end home studios industrial installations and live pro sound
environments. The DDA1:6 can therefore be used in a number of applications.
The DDA1:6 features one transformer balanced audio inputs on a Neutrik XLR. This input is
then routed via the front panel ‘Loop Through’ or ‘Renormalising’ switch to 6 transformer
balanced outputs also on Neutrik XLRs.
When in ‘Loop Through’ mode the AES3 input is sent straight to the 6 off AES3 outputs and
the signal present at the output will be identical to that received by the input. Loop through
is done with no delay to the signal and therefore is most useful if the AES3 signal is synced
with another source through the users’ production chain.
When in ‘Renormalising’ mode (the most common way to use the unit) the incoming signal is
cleaned up and the output signals will have clean clock edges and be as close to their initial
source as possible. The only disadvantage of renormalisong is that the incoming signal is fed
via a high quality AES3 receiver chip and it takes 1 sample to produce the cleaned up output.
The DDA1:6 works with all digital signals from 16 – 192 kS/s and up to 32 bit.
The DDA1:6 is powered from an internal switch mode mains power supply fed from a filtered
IEC mains plug suitable for use Worldwide. It has an internal fuse for safety. The unit can also
alternatively be powered from an external +/-12V DC power source (such as the Signature
Series PS1). If both mains and external DC power sources are present then if one power
source were to fail the unit would continue to work seemlessly from the other source.

mounted or stood (using the supplied feet) on top of desks or worktops.
INSTALLING SIGNATURE SERIES IN A 19” RACK
Firmly hold the signature subrack within the 19” rack and locate in 1RU of space. Use the
supplied 6mm rack screws to securly attach the unit to the rack.
INSTALLING ADHSIVE FEET FOR NON PERMANENT TABLE TOP MOUNTING
Remove the front rack ears (if they are not required) turn the unit upside down and attach
the supplied 4 sticky feet as per the above drawing.

S APPING RACK EARS TO ALLO THE REAR TO BE INSTALLED AT THE FRONT OF A
RACK
First remove the 4 silver button head screws that fix the rack ears onto the front of the unit as
shown in the top picture above.
Remove the rack ears and turn the unit around for access to its back panel.
Re-fit the 2 rack ears using the same 4 silver button head screws that were removed from the
front as per the bottom picture above.
USING THE MOUNTING HOLES FOR PERMANENTLY ATTACHING THE UNIT ABOVE OR
BELO A ORKTOP/ DESK
Use either the top or bottom mounting holes as indicated above to use suitable screws to
attach the signature unit to a worktop or bench. **PLEASE ENSURE THAT YOU USE SUITABLE
FIXINGS**
