Questions And Answers

Owner’s Reference GCHA Headphone Amplifier

The GCHA is best left powered on at all times. The power consumed is negligible and keeping it powered on will make sure the internal AC capacitors stay charged and the amplifi er and Gain Cells sound their best whenever you are ready to listen to music.

There is no harm in leaving the unit on at all times as the lifespan of the GCHA will be unaffected.

There is a user replaceable internal fuse inside the GCHA. However, this fuse should not be replaced without fi rst consulting the factory service center for advice. It would be unusual for this fuse to blow and may indicate something is wrong with the unit.

The GCHA will power any headphone made with 16 Ohm or higher impedance. Most headphones have considerably higher impedance than the minimum 16 Ohm.

Note that listening to headphones at extremely loud listening levels may damage your hearing. Enjoy your music, enjoy the superb dynamics of this high-end piece of equipment, but protect your ears. Hearing damage from overly loud music is typically irreversible.

The GCHA will automatically switch back to the analog inputs when no digital signal is present. This means once the Windows Media

Player or the CD or DVD player, built into the computer, is stopped, the GCHA will switch back to the analog audio inputs.

Placement of the GCHA is not critical for most components. In most cases, it may be placed as close to or as far away from the system or the computer, as need be. However, it may not be advisable to place the GCHA too close to a CRT computer monitor. The large transformer inside the GCHA may cause some slight color shift in CRT monitors if placed too close. We would recommend keeping the GCHA at least one to two feet away from any CRT monitor. LCD screens are fi ne.

Hum may also be an issue with the GCHA if placed too close to a sensitive piece of equipment such as a phono preamplifi er or turntable. The GCHA has an exceptionally large power transformer inside. This transformer can generate a fairly large magnetic fi eld which can induce hum into sensitive equipment in close proximity.

Isolation through the use of spikes, cones or Sorbothane feet is recommended for the GCHA if space and budget allows. Isolation of any piece of high-end stereo and theater equipment is always recommended wherever practical.
