The exclamaon point within an equilateral
triangle is intended to alert the user to the
presence of important operang and
maintenance (servicing) instrucons in the
literature accompanying the product.
The lightning flash with arrowhead symbol
within an equilateral triangle is intended to alert
the user to the presence of uninsulated
“dangerous voltage” within the product’s
enclosure that may be of sufficient magnitude to

SAFETY INSTRUCTIONS
READ THOROUGHLY BEFORE PROCEEDING
Read These Instructions
All safety and operang instrucons should be
read before the DPU is operated.
Keep These Instructions
The safety and operang instrucons should be
retained for future reference.
Heed All Warnings
All warnings on the product and in the operang
instrucons should be adhered to.
Do Not Use This Apparatus Near Water
The risk of electrical shock is greatly increased
when operated in a wet environment.
Clean Only With Dry Cloth
Unplug the DPU from the wall outlet before
cleaning using a damp cloth. Do not use liquid or
aerosol cleaners.
Do Not Attempt Self-Repair
Contact McCauley Sound Inc. when servicing is
required.
Do Not Defeat the Grounding Plug
If the provided plug does not t into your outlet,
consult an electrician for replacement of the
obsolete outlet.
Do Not Compromise the Power Cord
Protect the power cord from being walked on or
pinched parcularly at plugs, and the point where
they exit from the DPU.
Do Not Use Unsupported Components
Only use aachments and accessories provided by
McCauley Sound Inc.
Do Not Mount In Unstable Apparatus
If mounted improperly the DPU may fall, causing
serious bodily harm and serious hardware damage.
Do Not Block Any Ventilation Openings
Slots and openings in the DPU side are provided
for venlaon, to ensure reliable operaon and to
protect from overheang. These openings must not
be blocked or covered.
Keep this manual in a safe and accessible place for future reference.

For serial communicaon, a standard male to female RS232 cable with
DB-9 connectors is required for connecng the DPU to a host PC.

The DPU features an internal USB to serial adapter that requires a USB cable
for connecon to the host PC. USB drivers are included with the McCauley DSP
console installaon: the drivers can be found under the installaon directory.

Input and output channels can be muted and un-muted by using the mute buon located beneath
each channel’s output level LED. When a channel is muted the buon will illuminate red.

Input and output channels can be selected by using the menu buon located beneath
each mute buon. When a channel is selected the buon will illuminate green. While
selected you are able to modify various parameters through the display window.
Linking mulple channels together is accomplished by pressing and holding the menu buon for
the rst channel. While sll holding down the rst buon, select the other channels. This eases
programming for the same parameters across mulple channels. Mulple inputs can be linked
together and mulple outputs can be linked together but inputs and outputs are linked separately.

FIR lter slope steepness is controlled by allocang space for coecients. The DPU contains
a total of 1600 memory locaons for all of the outputs. Use this page to allocate memory
based on your applicaon. Exceeding 1600 lter taps can lead to unexpected behavior.
□1 to 8 Select the order for output FIR lters in 50 tap steps. The sum of all
taps cannot exceed 1600.
