Transformers
Most of the transformers used in our products are hand-wound to ensure
maximum quality. This provides a guarantee that current capability, efficiency, and
radiated noise are all kept within our demanding parameters. Another critical aspect of
the transformer is mounting; all transformers are securely mounted in their respective
chassis. Transformers are massive, and if not securely mounted can cause failure among
internal components due to vibration.
Power Supplies
Regulated or Unregulated? For years amplifier designers have debated which
type of power supply is best. What's the truth about power supplies? They each have
advantages and disadvantages and there is no, one, best type. Limiting yourself to one
type of power supply limits your amplifier design flexibility. ZAPCO uses both types of
power supplies depending on the intended use of each amplifier, as well as expected
current demands and operating environment.
Zapco Digital
Who has the number one name in state of the art audio equipment?
Zapco!
But, when most people think of Zapco, they picture compact, powerful, great sounding
amplifiers. While this picture is true enough, it misses one big piece of the Zapco legend.
Signal Processing!
Zapco virtually created the concept of high sound quality processing in the late 70's
when we created the PEQ. This was a high voltage preamp/EQ with and audiophile input
stage and 9 bands of equalization for each channel. It brought a whole new level of
performance to car sound. In the 90's the name was changed to SEQ and the unit is still
in production today.
In the 80's we took processing to another new level with the PX. This was the first
audiophile quality preamp EQ with a multi-order crossover. In addition, all four EQ bands
were parametric, so now you could customize the EQ parameters to you car. The result:
By the late 80's even non-Zapco dealers had to have a source of PX's for all their
competition cars.
The next leap was in the 90's, when Zapco introduced the SX, (later to become the
SX-SL). This unit expanded the Parametric EQ to 5 bands, added dual high pass and three
way band pass crossovers, added variable crossover slopes, bass-to-highs balance, and
SymbiLink™ Balanced inputs.
In 2004 Zapco Introduced the DSP-6, stand-alone, PC controlled Digital Signal
Processor. We also introduced the DC Reference line of Amplifiers. These were the first
ever PC controlled amplifiers with on-board DSP's for each and every channel. The DC
Reference amps were controlled by the revolutionary Zapco DPN control network that
allowed a single CP screen ar DRC controller to control each amplifier in the system
separately and to apply memory settings globally to the network.
