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.

Each input and output has a ve segment LED for audio level display. The meter scale is factory
set so that 0 on the meter is 0dBu (0.775Vrms) and ranges from -20 through clipping.

Parameter data values are changed by using the travel velocity sensing rotary thumb
wheel. The increment of adjustment varies in size based upon the speed and distance
of wheel rotaon. This aids in both small and large incremental data modicaons.

The DPU is powered by a low noise universal input power supply with an
operang range from 90VAC to 240VAC, 50-60Hz. Never defeat the grounding
on the DPU’s power supply; this could result in injury or death.

The power supply uses a slow blow type T2.5A-250V fuse. In the event of fuse failure,
always replace with the same type and rang fuse. If the fuse fails immediately aer
replacement, disconnue use of the DPU and contact McCauley Sound Support.

The M204, M306, and M408 use AES14-1992 standard XLR connecons. The M808 uses Phoenix
Connecon 1754562 MSTB 2.5/ 8-ST COMBICON (EUROCON) connectors. Inputs and outputs
are electronically precision balanced to obtain maximum common mode rejecon. To prevent
signicant signal loss when an unbalanced signal is used, consult Appendix E for connecon
recommendaons. It is strongly recommended that balanced signals be used whenever possible.

There is no analog gain adjustment on the M Series DPU, all the processing (including
gain) is performed digitally. As a consequence of this, it is important to supply the
processor with the opmum signal level to achieve good signal to noise performance as
