Temperature Guidelines
The DP/Pro contains computerized and electronic circuitry that can be susceptible to damage when
exposed to extreme temperature changes. When the DP/Pro is brought inside after sitting in a cold
climate (i.e., the back seat of your car), condensation builds up on the internal circuitry in much the
same way a pair of glasses fogs up when you come inside on a cold day. If the unit is powered up as
this condensation occurs, components can short out or be damaged. Excessively high temperatures
also pose a threat to the unit, stressing both the internal circuits as well as the case. With this in mind,
we advise you to follow these precautions when storing, mounting and setting up your DP/Pro:
• Avoid leaving the DP/Pro in temperatures of less than 50 degrees Fahrenheit or more than 100
degrees Fahrenheit.
• When bringing the DP/Pro indoors after travel, allow at least 20 minutes for the unit to reach
room temperature before powering up. In the case of extreme outdoor temperatures (below 50
degrees Fahrenheit or above 100 degrees Fahrenheit), allow an hour or more before powering up.
• Avoid leaving the DP/Pro inside a vehicle exposed to direct sunlight.
Se t t ing A nalog Input Le ve ls
The DP/Pro can accept +4dB or -10dB input levels. The rear panel I/O level switch should be set to
match the output of your sending device.

I/O Level
The DP/Pro’s Headroom LEDs show the level of incoming analog audio whenever the Meter Function
switch is in the out, or up, position. The LEDs under the Meter Function switch show the current state
of the Headroom LEDs.

The optimal input level for the DP/Pro is just below the point at which the red Headroom LEDs light.
Since the DP/Pro provides its best signal-to-noise performance when its Input Level knob is set
straight up, it’s a good idea to set the knob to this position and then adjust the output levels of your
sending device to obtain a healthy Headroom LED reading.

Battery Replacement
The DP/Pro “remembers” its effects and various settings even when its power is turned off, since it
contains a battery which keeps its memory intact. All batteries eventually become discharged, and
