Unpacking Your A 23+ & Placement Guidelines

Unpacking Your A 23+

Carefully remove your A 23+ from its shipping carton and locate the enclosed accessories:

• AC power cord

• A 12V trigger wire for auto turn on. It has a mono 3.5 mm mini plug at each end.

While you are unpacking your A 23+, inspect it thoroughly for possible shipping damage and tell your

Parasound dealer immediately if you find any evidence of shipping damage.

This would be a good time to make a copy of your sales receipt to store with the A 23+’s original packing.

Note: Please save and store both the inner and outer cartons and, most especially, the foam

packing inserts to protect the A 23+ if you have to move it or ship it. You may wish to flatten the

cardboard cartons to save room in storage after cutting the taped seams on the bottom flaps.

Placement Guidelines

The A 23+ will be easier to use and will last longer if you follow these simple guidelines:

• Place the A 23+ on a surface that will adequately support its weight.

• Use input and output cables that are long enough to leave some slack; that will enable you to pull the A 23+

out of a cabinet to check or to change connections without inadvertently disconnecting cables.

• The A 23+ should never be placed in a completely enclosed cabinet.

• Place your A 23+ where you can route input and output signal cables as far as possible from any AC cords.

• Where input interconnects must cross AC cords they should do so only at a 90° right angle.

Ventilation Requirements

• Always position the A 23+ horizontally.

• The A 23+ should never be stacked directly above another power amplifier or directly below another component.

• Do not install the A 23+ in an unventilated equipment cabinet or compartment. Pockets of stagnant hot air

can build up even in a cabinet with an open front and back. A ventilation fan is recommended to prevent “hot

spots” in confined spaces.

AC Mains Voltage

Make sure the 115 V/230 V Voltage Selector switch on the A 23+’s back panel is set for the

correct AC line (mains) voltage before you plug in the power cord. It can be seriously

damaged if this switch is set for the wrong AC mains voltage.

In the 115 V position the A 23+ can safely operate with AC Line voltages between 110-125 V which is

correct for North America, Mexico, and Taiwan. In some countries, such as Brazil, AC voltages differ

by region. Most other countries require setting it to 230 V. With the 230 V setting the A 23+ can

operate safely with AC line voltages between 220-250 V. If the AC Voltage Selector is changed the

rear panel fuse value must also be changed. The A 23+ operates on 50Hz or 60Hz AC.

Note: An A 23+ that has been damaged by connection to the incorrect AC mains voltage

is not covered by the Parasound warranty.

AC Power Cord

The AC cord supplied with your A 23+ is a high quality IEC type cord. Please connect it directly to an AC wall

outlet or power conditioner that is always “live.” If possible, plug your A 23+ into the same AC outlet that your

preamplifier is plugged into. If different AC outlets are used for the A 23+ and other components, (including a TV

or video projector) the ground potential may be higher or lower between the outlets, resulting in audible hum.
