With Legatto Legacy Phono internal boards.
Conceptually, a preamplifier serves two primary functions, traffic control and volume control. Gryphon Pandora dispenses with conventional tone controls, balance knobs, mono switches and other superfluous circuitry to reduce interchannel and signal path coloration to an absolute minimum.
When in pristine condition, contacts in the signal path have little impact on sound quality, but this condition rarely lasts for long. In order to prevent signal loss through oxidation, all switches, relays and the volume control incorporate gold-plated contact surfaces. Source selector relays (three balanced inputs, two single-ended, one tape loop) are also hermetically sealed to prevent the accretion of grime on contact surfaces. Relays ensure the shortest possible signal path and are subject to negligible wear.
The Gryphon Pandora volume control is a microprocessor-controlled 85-step attenuator for extreme precision in setting the desired listening level. Select resistors and relays ensure long life and perfect matching at all levels. The front panel volume control is a heavy wheel with double ball-bearings for smooth running.
