CPA402 Power amplifier

CPA402 Power amplifier

Nytech CPA402 Power amplifier with oak wood trim

The CPA402 power amplifier compliments the CP202 pre amplifier perfectly.

Although a similar spec and power output to the CA352 integrated amp (on paper), the CPA402 adds an extra layer of detail and enjoyment to your music that you have to listen to to understand. Let your ears do the deciding!

The CPA402 was designed for use with the CP202 but it can be used with other equipment as it has phono (RCA jack) inputs as well as XLR.
It is also possible to control the CPA power from an external amp if it has the facility to do this via a special XLR “control” cable.
A version with a front panel on/off button is also available to special order.

The CPA402 is available with several real wood trim options.

Welsh Walnut
American Walnut
Light Oak
Black ash

Other woods are possible to special order. Please contact us for more details.

Active loudspeaker systems

The CPA402 has one final trick up its sleeve. It has a connector inside for a two way active crossover board which converts the 402 into a 2 way (HF and LF) active loudspeaker monoblock so if you have an “active capable” loudspeaker (such as Kudos) you can upgrade a CP/CPA system to active by just the addition of a single extra CPA402 and a crossover board for your speaker type.

Active systems are still very much under development so please contact us for the latest information.
