AC Voltage Selection Switch
The Suite 7.1 can operate on either 110-120 Vac or 220-240 Vac operation. When you purchased
the amplifier, the rear panel voltage selector switches were preset for the proper voltage in your area.
Nevertheless, it’s wise to double-check it before plugging into an AC outlet. If you move to a
location with a different line voltage, you can easily convert the Suite 7.1.
Maintaining Your ADA Suite 7.1
Your ADA Suite 7.1 power preamplifier requires no periodic maintenance and has no user-serviceable
parts inside. To avoid the risk of electric shock, do not remove its top cover. The preamplifier’s exterior
can easily be cleaned with a soft cloth pre-moistened only with a few drops of water or glass cleaner.

Warranty and Returning the Suite 7.1 for Factory repair
ADA preamplifiers are under warranty for three (3) years effective upon the dealer’s receipt of the
product. If ADA determines that you should send your unit to ADA for factory repair, you will be given
a Return Authorization (RA) number. This RA number must be clearly marked on the outer carton.
Enclose a copy of your original purchase receipt to validate warranty coverage. It is the dealer’s
responsibility to pay for shipping to ADA. Be sure to ship the unit with adequate insurance. After
repair under warranty, the unit will be returned to you via prepaid within the continental United States.
Important Notice - Shipping the Preamplifier to ADA
Before shipping the unit, you MUST re-pack the unit into its fitted molded foam insert and its original
carton. If you do not have the original packing cartons and foam inserts, call us for new packing
materials that we can provide to you for a nominal charge. Use of any other carton and packing materials
will probably result in shipping damage, and refusal of the unit. Common carriers such as UPS seldom
pay claims for damage incurred during shipment when a product is surrounded only with Styrofoam
“peanuts” or otherwise improperly packed. We cannot stress enough the importance of properly packing
your preamplifier. Shipping damage resulting from inadequate packing can cost you a lot of money and
significantly increase the time required for repair. Ship the unit with adequate insurance. After repair
under warranty, the unit will be returned to you via prepaid UPS within the continental United States.
