Min button, then the Set Max button, then the Apply button. To clear these settings, press CLR Min

STEP 7: To turn the system off, stop playback on the source device. Hold the Standby button in the

middle under the LCD touchscreen or on the remote down for 5 seconds. The unit will enter cool-down

mode for 10 seconds, during which no buttons will work. After cool-down mode finishes, you can turn

the unit back on again as described in Step 1 above.

Maintenance

The Altair II requires no regular maintenance.

If the preamplifier's surface becomes dusty, simply wipe it off with a soft dry cloth. Do not spray

cleaners on the surface.

To clean fingerprints from the surface of the preamplifier, spray a small amount of mild window

cleaner such as Windex onto a soft dry cloth, then use the cloth to remove the fingerprints. Do not

spray the cleaner directly onto the preamplifier.

Preamplifier will not turn on

1. Check to see if the front blue LED on the power supply is illuminated. If it is not, try the following

steps in order. After you perform each step, touch the Power button on the front of the unit and wait a

few seconds to see if the blue LED is illuminated. If any one of the steps restores the power (i.e.,

allows the Power button to turn the unit on), there is no need to continue to the next steps.

A. Check power cable connections between the wall and the Altair II's power supply. Push the wall

plug and the connector at the power supply in firmly.

B. Check power cables between Altair II and power supply. DO NOT pull out these cables while the

power supply is on.

C. Make sure the master power switch on the rear of the power supply is turned on.

D. If the Altair II is plugged into an AC line conditioner, make sure the line conditioner is turned on.

F. Flip the master power switch off and on again. This will reset the Altair II's internal circuit

breaker.

G. Check the circuit breaker for the AC circuit that the Altair II is plugged into. If the breaker is

tripped, flip it back on. If it will not turn on, there is likely a short circuit somewhere in the lines

or in a device connected to this AC circuit. Check the power cords for your components to make

sure none have been damaged.

H. If none of these conditions restores power, it is possible one of the Altair II's internal fuses is

blown. Do not attempt to change the fuse yourself—the Altair II requires the use of special high-

voltage fuses that are not commonly available. Contact your Constellation Audio dealer for service.

Preamplifier is on but no sound is produced

1. Make sure the front LED on the power supply is glowing blue, indicating that the preamp is powered

up and not in warm-up mode.

2. If the LED is lit and the Standby screen is visible on the LCD panel, press the Power button under the

front LCD or on the remote to restore sound.

3. If the LED is lit and the volume numbers on the LCD panel are flashing, hit the Mute button on the

front panel or on the remote to restore sound.
