Subwoofers
You can easily
use a subwoofer with your Ion but we don’t recommend you use the
High-Level Input
connections on your subwoofer.
The High-Level Inputs are not designed to work wi
th the outputs of a PowerDAC and while you won’t
likely damage anything, you may be unsatisfied with the sound quality. Instead, we recommend that you
use the line level inputs on your subwoofer and connect them to the RCA Analog Outputs on the Comet
–
when the Ion is your amplification device, the Comet will also output the full audio range to the RCA
Analog Output for the express purpose of using a subwoofer. Also, set your phase selector to 0°. Adjust
the subwoofer’s Crossover and Gain (or Volume) knobs
to match your particular system.
Connecting to AC Power
The best performance is obtained when the EXOGAL Ion is plugged directly into the wall with the power
adapter provided. The EXOGAL Ion 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 before connecting or removing a cable. It is unlikely that a static shock will damage
the unit, but it may cause the EXOGAL Ion
circuitry to “lock
-
up” (see Troubleshooting: Lock
-up

Inputs and outputs can be safely connected to the EXOGAL Ion:
Before the unit is powered up
When the unit is in Full-Mute mode
When the unit is in Standby Mode
