The DPN Network

With the Zapco DPN Network, you can address up to
10 amplifiers into your network and control each one
individually from the same pc screen.

Do you plan a big system? With the Zapco DPN and the Zapco

DC amplifiers, you can have up to 60 channels of digitally
processed Zapco sound.

With the Zapco DC systems there are simply no limits.

One amp or ten amps…It’s all up to you

Addressing your amps in the Network

USB Cable connects DC Amplifier to PC

1 2 3 4 5 6

Addressing is by 6
position DIP Switch.

 Pins 1 to 4 address the

Amplifiers

 Pins 5 and 6 are not used

and should always stay in the
up position.

Each Amplifier in the network must have a different

combination of pins 1 to 4 so each will have a unique position in the

network

connects each DC- Series
amp to the others in the
network

DC-Series Speaker Output Impedance

(Did you see the Low-Z Switch? Do you want to know more?)

For Your Information:

Zapco Rail Voltage Monitoring is a system

to protect your sound when speaker
impedance drops below normal range.

Example: At 4Ω a DC352 has 100W RMS at

rated distortion. At 2Ω it has 175W RMS at
rated distortion.

But, what happens if there is a problem in a passive crossover and there is an impedance drop?

Or if a ported enclosure causes a 2Ω woofer to go down to only 1Ω?

The rail voltage monitoring system reduces rail voltage so the amp does not go into low-impedance
protection. Your music keeps right on playing. If you will be playing below 2Ω often, then you can engage

the Low-Z switch to lock in the lower rail voltage

The DSP-Z8

The DC-Series amps were designed to be the ideal
solution for every car.
But, not everyone will want to use the DC amps.
You may want to use the Z-Series or the Studio

Series amps.

Or, maybe you already have amplifiers and just want processing.

The DSP-Z8 puts all the processing power of the DC-Series amplifiers in a stand-alone digital
signal processor that can be used with any amplifier in any system.
All the control functions of the DC amps are right there in the DSP-Z8

The DSP-Z8 also adds Auxiliary Input functions to the Zapco processing system.

The PC Control Screen

This is the PC control Screen if you use the DC-Series Amplifiers, or if
you use the DSP-Z8. All the processing functions are the same for both
