Nuforce P-9 is the brain child of Demian Martin, a distinguished industrial designer and consultant.

Housed in two chassis, the low-noise, high-performance Nuforce P-9 premaplifier is a breakthrough product. One chassis contains three power supplies and microprocessor control logic; the second chassis contains an analog volume control, input selection relays, and sensitive analog circuit components.

The heart of the P-9 boasts an all-discrete, precision-operational amplifier module.

The inherently stable P-9 gain circuit has no capacitors or DC-servos in the signal path.

Much attention has been paid to isolation. The amp modules are seated within heavy copper shields with internal thermal insulation to prevent thermal drift or signal-related heating capable of interfering with the preamp's operation.

The control system sends DC to the relays and the potentiometer's motor only. No logic circuitry with its clocks and fast edges introduces noise into the analog section's sensitive, low-level signals.

For audiophiles who want to integrate a home theater system into an uncompromising audio system, the P-9 incorporates a unique bypass system that connects the power amps for the main speakers directly to the AV processor or AV receiver amp, as well as a 12V trigger, for multi channel amplifier control.
