Preamplifier is on but no sound is produced

1. Touch the front touchscreen to see if it illuminates. If it does not, press the Power button under the

front LCD to turn the unit on.

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.

4. If neither the Mute nor the Power button restores the sound, 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, or select the desired input using the remote.

B. Check that the source component is on and playing back—i.e., if it is a CD player, make sure

that the CD is playing and not in pause mode.

D. Check the connections between the PREAMP 1.0 and your amp, and between the PREAMP 1.0

and the audio source device. 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.

E. 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.

F. 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 1.0 is set to output maximum volume, damage

can be done to your speakers and amplifiers.

G. If none of these actions restores the sound, contact your Constellation Audio dealer.

Sound seems unfocused

1. Play a CD of typical pop vocals and sit in front of your speakers at an equal distance from both (at

least 8 feet away from each speaker). If the vocals seem to come from between the speakers, they are

connected correctly. Alternatively, you can use the "barking dog" test from the Stereophile Test CD or

a similar phase check test from another test CD.

2. If the vocals seem to come from all around you, make sure that the cables on your amplifier are

connected properly, with the marked connector or cable connected to the positive (red or +) binding

post on the amplifier, and the unmarked connector or cable connected to the negative (black or -)

binding post.

3. If you need to change the speaker cable connection, turn the amplifier off first. To avoid possible

electrical shock or damage to the amplifier, you must discharge the energy stored in the power supply.

To discharge the power supply, turn the power off with music playing. It may take up to a minute or so

for the sound to die out. After the sound dies out, it is OK to change or adjust the cables.

Sound comes from the wrong speaker

If left-channel sounds are coming from the right or vice-versa (i.e., the violins in an orchestral

recording come from the right speaker, not the left), check the cable connections between the source

and the PREAMP 1.0, and the PREAMP 1.0 and your amp. Make sure left-channel cables are connected

to the left channels of the PREAMP 1.0 and amp, and right to the right channels.

Only one speaker is working, or one speaker is playing a different piece of music

1. Check each cable, starting with the source component. Make sure the left channel of the source

goes to the left input on the PREAMP 1.0 (which is on the right side, as you're looking at the back

panel), and the right channel to the right input (which is on the left side). On the back of the PREAMP

1.0, the left and right inputs are NOT next to each other. They are on opposite sides of the unit. In

other words, the XLR input numbers are 1, 2, 3, 3, 2, 1, and the RCA input numbers are 4, 5, 6, 6, 5, 4.
