original setting. To clear the setting, press either CLR Min or CLR Max as appropriate, or press Default

to clear both settings.

STEP 6: If you want to use the PREAMP 1.0 in a home theater system, in conjunction with a surround-

sound processor, you should set up one input for home theater bypass. When you switch to this input,

volume and balance will be at fixed settings and your channel balance adjustments in the surround

processor will be preserved. To do this, first select the input you want to use for this function. Now

adjust the volume on the PREAMP 1.0 to the desired level. Push the multifunction button labeled

Setup. Push the Set Min button, then the Set Max button, then the Apply button. To clear these

settings, press CLR Min then CLR Max, or press Default.

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 PREAMP 1.0 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.

Troubleshooting

Preamplifier will not turn on

1. Touch the front touchscreen to see if it illuminates. If it does 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 AC power cord connection between the wall and the PREAMP 1.0. Push the wall plug and

the connector at the preamp in firmly.

B. Make sure the master power switch on the rear of the preamp is turned on.

C. If the PREAMP 1.0 is plugged into an AC line conditioner, make sure the line conditioner is

turned on.

D. Flip the master power switch off and on again. This will reset the PREAMP 1.0's internal circuit

breaker.

E. Check the circuit breaker for the AC circuit that the PREAMP 1.0 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.

F. If none of these conditions restores power, it is possible one of the PREAMP 1.0's internal fuses is

blown. Do not attempt to change the fuse yourself—the PREAMP 1.0 requires the use of special

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

service.
