PANDORA’S FOUR BOXES
In Greek mythology, Pandora was created at Zeus’ command as the first woman on earth. Her name means “the all-gifted”, because the gods endowed her with numerous precious talents. From Aphrodite, she received beauty, divine grace, charm and harmony; from Apollo, the gift of music; from Hermes, the power of subtle persuasion; from Athena, soul and from the Graces, love, tenderness, beauty, kindness, pleasure, creativity, artistry, and sensuality.

We have captured these virtues in the four-chassis Gryphon Pandora preamplifier with total isolation of left and right channels on separate chassis and dedicated dual mono power supplies in individual chassis to protect the audio signal from any interference.

The dual mono aspect of the design is taken to the practical extreme with separate detachable power cords and separate power switches for each channel.

Thanks to creative engineering and unbridled freedom in its design and execution, Gryphon Pandora is empowered to reveal more of the recorded source than any previous preamplifier. Only the finest components, selected for both technical and audio parameters, have been implemented, including Japanese Takman resistors and Charcroft Z-Foil resistors. Signal transmission between preamp and power amp takes place in fully balanced mode for low signal loss and minimal distortion.

Pandora also marks the introduction of a newly developed single-ended Class A input buffer stage consisting of only two transistors and a single resistor to maintain the transparency, speed and openness of the audio signal.

IN CONTROL
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.

CONTROL MENU
The outward simplicity of the Gryphon Pandora conceals a variety of custom adjustments that are readily accessible without cluttering the front panel. For an exceptional level of convenience and user-friendliness with no negative impact on audio performance, Gryphon Pandora is equipped with a microprocessor-controlled menu of practical features: input naming, max level setting, start level setting, left/right channel balance (6 dB in 1 dB increments), input level matching, fixed-level AV throughput, display brightness (100%, 75%, 50%, 25%, Off), Green Bias setup and default restore.

GREEN BIAS
When connected via Gryphon’s proprietary Green Bias Link to a Gryphon power amplifier with Green Bias function, Gryphon Pandora can control available Class A output, reducing power consumption and running the amp slightly cooler for less critical use. This feature adjusts the amplifier bias in relation to the preamplifier volume control for exactly the right amount of Class A power on demand as needed with massive instantaneous power reserves ready and waiting.

POWER SUPPLY
With twin 90,000 microFarad capacitor banks, Gryphon Pandora actually generates enough juice to drive many integrated amps or power amplifiers. The overkill power supply ensures rock-solid control, headroom and signal purity under any imaginable conditions. In addition, the Pandora power supply incorporates outputs to drive external components such as the Gryphon Legato Heritage phonostage, both as a stand-alone unit or as modules installed in the Pandora.
