Volume control

Mute control

Operating the GCC Control Amplifi er is a fairly straightforward procedure.

From the front panel there are fi ve controls:

Volume control

Mute control

Up selector

Down selector

Power button

The volume control is a rotary knob that the user can turn up and down to control the gain of the Gain Cell and the loudness of the amplifi er. While this is not an ordinary attenuator, its function of turning the volume up and down is the same.

This control has been ergonomically designed with the best human interface we could devise. Its step size varies depending on where you are in the range: lower ranges have larger steps and higher ranges have fi ner steps. Above a certain point, the volume will increase in 1/10th dB steps if you turn the control slowly.

The Mute control on the front panel or the remote will mute the GCC’s audio when pressed and will be automatically deactivated and return to

the original volume setting if the user turns the volume control up or down or if you press the mute button again.

Balance control

Balance functions are only available through the remote control. The blanace function is clearly marked on the remote control.

Up/Down selector

Power Button

Up Selector and Down Selector buttons toggle through the inputs (and toggle through the setup choices while in the setup mode), which are displayed on the front panel. The remote control allows you to select individual inputs without toggling through the choices.

As you toggle through the input choices, the volume will automatically ramp up and down quickly so there’s no loud “pop” noise between inputs.

The power button is cleverly disguised as the PS logo (or vice versa depending on your point of view). Press the logo and the unit will toggle on or off. Pressing the front panel power button does
