Connecting the Comet

Your EXOGAL Comet Computer DAC uses an external power supply which is designed to work with

line voltages from 100VAC to 240VAC, 50/60Hz. The supplied power adapter can accept different

sets of prongs to allow it to plug into the wall socket in different countries. Attempting to use a different

power supply may damage the unit. Damage caused by improper operation is not covered by

warranty. If you would like to use a different power adapter, contact your EXOGAL dealer.

Connecting to AC Power

The best performance is obtained when the EXOGAL Comet is plugged directly into the wall with the

power adapter provided. The EXOGAL Comet has some power conditioning and surge suppression

built in. It should not be necessary to use surge protectors power conditioners or aftermarket power

cords, some of which may degrade the sonic performance. If you wish to experiment with any of

these devices, work closely with your local dealer – and most of all, trust your own ears.

Avoid allowing static shocks to be applied to the inputs or outputs. To prevent static shocks, touch

any grounded surface, such as the EXOGAL Comet chassis, before connecting or removing a cable.

It is unlikely that a static shock will damage the unit, but it may cause the EXOGAL Comet circuitry to

“lock-up” (see Troubleshooting: Lock-up – page 10).

Inputs and outputs can be safely connected to the EXOGAL Comet:

Before the unit is powered up

When the unit is in Full-Mute mode

When the unit is in Standby Mode

We strongly recommend that you use your EXOGAL Comet connected directly to your power ampliﬁer.

Even if you purchased your EXOGAL Comet with the intention of connecting it to your preampliﬁer,

we suggest that you try direct connection to your ampliﬁer. Many listeners are surprised by the

improvement in performance over even the most expensive preampliﬁers.

To connect your EXOGAL Comet to a power ampliﬁer, ensure that your power ampliﬁer is turned off

then connect your chosen interconnects from the EXOGAL Comet outputs to the ampliﬁer’s inputs.

Using with a Preampliﬁer

While the EXOGAL Comet was designed and is intended to be used without a preampliﬁer, no

compromises were made in its design that will prevent excellent operation in a conventional system

with a preampliﬁer.

When using a preampliﬁer, set the EXOGAL Comet volume control to its maximum level.

The EXOGAL Comet Volume Control is factory set to 50% so that you can hear it some music when it

ﬁrst starts up but, depending on the sensitivity of your ampliﬁer you will not “blast” yourself inadvertently.
