Maintenance

The Perseus requires no regular maintenance. If the phono preamp'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 Perseus, 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

Unit will not turn on
1. Try the following steps in order. After you perform each step, touch the Standby button on the front of the
unit and wait a few seconds to see if the touchscreen illuminates. If any one of the steps restores the power
(i.e., allows the Standby 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 Perseus's power supply. Push the wall plug
and the connector at the power supply in firmly.
B. Check power cables between Perseus 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 Perseus 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 Perseus's internal circuit breaker.
G. Check the circuit breaker for the AC circuit that the Perseus 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 Perseus's internal fuses is blown.
Do not attempt to change the fuse yourself—the Perseus requires the use of special high-voltage fuses
that are not commonly available. Contact your Constellation Audio dealer for service.
Unit is on but no sound is produced
1. Try the following steps in order. If any one of the steps restores the sound, there is no need to continue to
the next steps.
A. Check you are on the correct input. Cycle through available inputs using the front touchscreen
controls. Remember that MC-1 and MC-3 are for XLR inputs, and MC-2 and MC-4 are for RCA inputs.
B. Check that the turntable is on and that the stylus is contacting the surface of the record.
C. Check the speaker icon in the lower right corner of the touchscreen. If there is an X next to the icon,
the unit is in mute mode. Press the Mute button directly beneath the speaker icon to restore the sound.
D. If one of the MC inputs is selected, push the Setup button under the LCD display, then push the MC
Load button on the LCD screen. If the resistive load is set to 000, turn the back-panel MC load
adjustment knobs to bring the loading up to the recommended resistance in ohms for your cartridge.
E. Check the connections between the turntable and the Perseus, and between the Perseus and the
preamp. If a cable is disconnected, reconnect it. If this does not restore sound, try substituting a
different set of cables in order to make sure the original set was functioning properly.
F. Check the connection between your amp and the speaker. Make sure the speaker cable has not
come loose. If it has, turn the power off on your amp, then re-install the cable.
G. Check that the volume is at a sufficient level. Do not turn the volume all the way up to check this, as
if sound is reestablished while the preamp is set to output maximum volume, damage can be done to
your speakers and amplifiers.
H. If none of these actions restores the sound, contact your Constellation Audio dealer.
