HIGHLIGHTS OF THE CP-700 DESIGN INCLUDE:

External power supply chassis generates seven separate power sources from three transformers.

A large135VA transformer with five separate secondary windings pro- vides maximum isolation for the plus and minus voltage sources for each channel, as well as the plus voltage used aboard the CP-700 for control circuitry.

Input selection is handled by special shielded, low-voltage relays with gold-plated silver contacts, rated to perform to their specifications for over 100 million cycles are ideal for switching low-level audio signals.

All unused input signals are disconnected from the chassis, giving the selected source what amounts to its own, dedicated preamp.

Single-ended sources are routed through an instrumentation-grade input buffer to generate a truly balanced (or symmetrical) signal. Un- like other single-ended to balanced conversion topologies, both legs of the resulting differential signal share the same path lengths and are truly symmetrical.

All signals, once in the balanced mode, are routed through a DC servo to remove any unwanted DC from the source. Coupling the signal in this way eliminates the need for sonically degrading DC blocking

caps, while protecting speakers from the possible damage or distortion resulting from passing DC through to the amplifier.

Separate stereo volume controls are used for each channel to maxi- mize stereo separation and allow better rejection of common mode noise and distortion.

Four-layer output buffer circuit boards provide optimum signal rout- ing and excellent distribution of power.

Six identical circuits per channel make up three discreet, three-stage differential buffer amplifiers (+ and – paths for each buffer). One is dedicated to the single-ended output. The other two are dedicated to the inverted and non-inverted signals on the balanced outputs. Because they have their own dedicated output buffers, both single- ended and balanced output stages may be used simultaneously with absolutely no degradation.

Optional phono modules (CPM) plug into the CP-700 motherboard to offer MM/MC phono gain and RIAA equalization.

The CP-700 monitors line voltage, frequency, AC phase and ground condition as well as internal temperature.

A TFT touchscreen display simplifies the user interface, reduces dis- play-related noise and allows users the convenience of customization.
