3
soft cloth. Do not use solvents, as they may damage the
amplifier.
12. Non-Use Periods: Unplug the amplifier’s power cord from
the outlet when the amplifier will be left unused for a long
period of time.
13. Object Entry: Care should be taken so that objects do not
fall through the opening of the enclosure.
14. Moisture: Do not expose the amplifier to dripping or
splashing. Do not place objects filled with liquids, such as
vases, on the amplifier.
15. Damage Requiring Service: Have the amplifier serviced by a
qualified service technician when the power cord or power
supply is damaged, the amplifier has been dropped or
the enclosure is damaged, something has spilled into the
amplifier, it has been exposed to rain, or the amplifier is not
operating properly.
16. Servicing: Do not attempt to self service the amplifier.
Contact Sonance Tech Support for servicing options.
17. Power Requirement: Do not connect the Sonance
amplifier to the accessory outlet of any other component.
Connection to a grounded mains power outlet is required.
WARNING: THE POWER (MAINS) PLUG SERVES AS THE
AMPLIFIER’S DISCONNECT DEVICE. THE DISCONNECT DEVICE
SHALL REMAIN READILY OPERABLE DURING OPERATION.
TO ENSURE THAT THE DISCONNECT DEVICE IS EASILY
ACCESSIBLE, THE USER SHALL NOT PLACE THE AMPLIFIER IN
A CONFINED AREA DURING OPERATION.
18. Storms: To prevent damage to components, unplug all
electronic equipment during thunderstorms.
19. Unplug by grasping the plug, do not pull on the cord.
WARNING: ANY CHANGES OR MODIFICATIONS TO THIS UNIT
NOT EXPRESSLY APPROVED BY THE PARTY RESPONSIBLE
FOR COMPLIANCE COULD VOID THE USER’S AUTHORITY TO
OPERATE THE EQUIPMENT.
NOTE: THIS EQUIPMENT HAS BEEN TESTED AND FOUND TO
COMPLY WITH THE LIMITS FOR A CLASS B DIGITAL DEVICE,
PURSUANT TO PART 15 OF THE FCC RULES. THESE LIMITS ARE
DESIGNED TO PROVIDE REASONABLE PROTECTION AGAINST
HARMFUL INTERFERENCE IN A RESIDENTIAL INSTALLATION.
THIS EQUIPMENT GENERATES, USES AND CAN RADIATE
RADIO FREQUENCY ENERGY AND, IF NOT INSTALLED
AND USED IN ACCORDANCE WITH THE INSTRUCTIONS,
MAY CAUSE HARMFUL INTERFERENCE TO RADIO
COMMUNICATIONS. HOWEVER, THERE IS NO GUARANTEE
THAT INTERFERENCE WILL NOT OCCUR IN A PARTICULAR
INSTALLATION. IF THIS EQUIPMENT DOES CAUSE HARMFUL
INTERFERENCE TO RADIO OR TELEVISION RECEPTION,
WHICH CAN BE DETERMINED BY TURNING THE EQUIPMENT
OFF AND ON, THE USER IS ENCOURAGED TO TRY TO CORRECT
THE INTERFERENCE BY ONE OR MORE OF THE FOLLOWING
MEASURES:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit
different
from that to which the receiver is connected.
• Consult the dealer or an experienced technician for help.
PRODUCT DESCRIPTION
The Sonance 16-50 (16-channel power) and 8-50
(8-channel power) amplifiers are rated at 50W per
channel into 8 Ohm loads, 100W per channel into 4
Ohm loads and 200W per bridged pair of channels into
8 Ohm loads. The internal stereo amplifier modules
are audiophile grade, high-efficiency Class D. The
amplifier is easily configurable for stereo and/or bridged
operation and can pass paging and doorbell chimes
when these signals are connected to the Bus Inputs.
The amplifier is compatible with 4 Ohm speakers in
stereo mode and 8 Ohm speakers in bridge mode.
Bridged operation is useful for higher power output
applications such as driving a passive subwoofer or an
outdoor 8 Ohm satellite and subwoofer system. Audio
source connections can be made into the ‘Local’ RCA
inputs for individual use or into one of the Bus Inputs
for distribution using the Zone Configuration Input
Assignment DIP switches. Busing allows for a single
source to be connected to one or more of the amplifier
zones without the need for additional cabling. It is
possible to turn multiple Zone Configuration Input
Assignment DIP switches to ON to allow for multiple
inputs to play together such as with use of paging or
door bell chimes. The paging and door chimes will then
be heard along with the audio source(s). The 16-50 and
8-50 has a comprehensive protection circuit that guards
against shorted outputs, over-current, over-temperature,
low AC voltage (brownouts) and excessive AC voltage.
PLACEMENT
The 16-50 and 8-50 features fan assisted cooling utilizing
vents on both sides of the chassis. Ensure the sides of
the amplifier have a least 3” (75mm) of clearance to
the sides of the rack or equipment cabinet to allow for
proper air flow.
The amplifier should be placed in a dry, non-condensing
environment with ventilation. Locate the amplifier so it
is completely isolated from temperature extremes, rain,
snow, direct sunlight and atmospheric contaminants. Do
not locate the amplifier outdoors. Any moisture related
damage such as from condensation is not covered by
the factory warranty. Although the amplifier includes
fan-assisted cooling, some heat is still produced. Locate
the amplifier on a shelf or at the lowest place in a rack
that has good circulation of fresh air to dissipate heat.
Do not place the amplifier in a closed cabinet or closet
with little ventilation as this can reduce its service life.
QUICKSTART GUIDE
The Quickstart Guide is intended for the installer who
is familiar with the 16-50 or 8-50 and has reviewed
the chapters on ‘Important Safety Instructions’ and
‘Placement’.
