Description
Gryphon Diablo Zena : Preamplifier
In good condition with guarantee and original box and accessories
The Gryphon Zena replaces the Athena ball-bearing volume wheel with touch-sensitive up/down buttons to create a volume attenuator consisting of 43 individual steps in 2 dB increments, with no more than two resistors in the volume control signal path at any given time.
Among the numerous component upgrades of the Zena is an ultra-precise array of SMD metal-foil resistors and hermetically sealed, gold-plated, ultra-low capacitance Pickering reed relays.
Equally crucial, the Zena volume attenuator is fully balanced, with no conversion of the signal from the XLR inputs to single-ended prior to attenuation, as was the case with the Athena. This simplification of the Zena signal path represents a major step forward in sound quality.
The Zena employs shunt regulators in the voltage supplies to the active circuits of the volume attenuator, in order to ensure a DC supply with ultra-low output impedance across a wide frequency band and optimal noise suppression.
