Exorcist

The Problem

The entire signal path from preamplifier input to speaker drivers contains conductive parts that can be magnetized.
Connectors, component pins and even circuit board copper traces may contain nickel or steel. In addition to being poor
conductors, these materials may be magnetized by DC current.

Most electronic devices have constant DC leakage, ranging from negligible to considerable, depending on the design.
Many preamps and power amps generate a DC pulse when switched on, before stabilizing. This is particularly true of
tube equipment. It has also been suggested that even the copper in cables contains oxides that may be magnetized.

The application of DC current is precisely the technique employed in the manufacture of magnets. High end connector
manufacturers and others are very much aware of this and subjective listening tests have often pinpointed the
degrading sonic effects of nickel. We would estimate that 95% of all gold-plated connectors have a nickel base beneath
the gold plating.

When an audio signal passes through a magnetic field, it is prone to magnetically induced distortion (MID) that
manifests itself as a “whiteness”, a lack of inter-transient silence and reduced soundstage depth.

The Solution

Those of you old enough to remember the venerable phono cartridge will also recall the indisputable benefits of
frequent use of a cartridge demagnetizer. The Gryphon Exorcist applies the same principle to the entire audio system
at line-level. (Do NOT use it on your cartridge or preamplifier MC/MM phono input. For cartridge demagnetization,
contact your authorized Gryphon dealer to audition the Gryphon Black Exorcist.)

How?

• Turn your system on with the volume all the way down.

• Connect the Exorcist to any line-level preamplifier input (Tuner, Tape, CD, DVD, Aux). NEVER connect the Exorcist to
a phono cartridge or to preamplifier inputs for phono/MC/MM/RIAA.

• Press the switch on the Exorcist for a second.

• Turn the volume up to a normal listening level.
You may choose to leave the room or protect your ears by other means during the process. The signal fades after

approximately 35 seconds. When treatment is completed, you will immediately experience the improvement that this
process can bring.

How often?

If you turn your system on and off, we suggest that you use the Exorcist every fifth time you turn on your system. If
your system is permanently powered up, use the Exorcist once a week.
