12 – 18. Front panel controls

The front panel includes an LCD touchscreen and two knobs plus five buttons positioned underneath

the display. These buttons allow you to control the Altair II without its remote. The functions of the

buttons are shown using icons on the Here are the functions of the buttons and knobs:

12. Balance

This knob adjusts left-to-right balance when an input screen is displayed—i.e., when an input is

selected. Turn the knob counterclockwise to shift the balance to the left, clockwise to shift the

balance to the right. An onscreen indicator will indicate if the balance is centered or how far it is

shifted to one side or the other.

NOTE: The light-dependent resistors used in the volume control reach optimal performance only after

warm-up. If the preamp has not warmed up for 15 to 30 minutes after initial power-on, you may notice

a slight balance difference between left and right channels. This can easily be corrected with the

balance control.

13. Volume

The volume control is always active when the Altair II is powered up and the mute is deactivated. Note

that the control is calibrated in negative decibels (-dB), reaching maximum volume at 0.0 dB and

minimum at -99.0 dB. Thus, when you turn the volume up (clockwise), the number on the front display

will decrease. When you turn the volume down (counterclockwise), the number will increase. The

adjustments steps are in 1 dB increments between -99.0 dB and -50.0 dB, and 0.5 dB increments from -

49.5 dB to 0.0 dB.

14. Home

This button brings you to the input select screen no matter which control screen you are currently

viewing.
