INTRODUCTION
Thank You for purchasing the Sonamp® 1230. Sonance has
taken the versatile Sonamp® 1250 and improved it by adding
more features, which makes the Sonamp® 1230 the most
versatile and reliable multi-channel amplifier available. Most
importantly, we listened to installers and end users and added
features that they wanted.
ADDITIONAL AMPLIFIERS
If additional Sonamp® 1230's are used, we recommend
separate 15 amp circuits for each amplifier due to the
enormous power capability and requirements of this product.
Non-buffered LINE OUT connections for left, right, and
auxiliary channels are provided. Within the limits of available
mains power, any number of additional Sonamp 1230
amplifiers may be daisy chained for larger installations.
ASSOCIATED COMPONENTS
A music reproduction system is only as good as its weakest
link. To avoid disappointment, your Sonamp® 1230 should be
used with other components of the highest caliber.
The Sonamp® 1230 is compatible with most high quality pream-
plifiers,tuners, CD/DVD players, and Mini Disc decks; as well as
better in-wall and cabinet mounted speakers from Sonance
and other reputable manufacturers.
CARE AND MAINTENANCE
Retain the safety and operating instructions for future reference.
1. Follow all warnings and instructions in this manual and
marked on the product.
2. Any service or repair required must be performed by
qualified, factory authorized personnel.
3. To clean your Sonamp 1230,use a soft brush,“canned air,”or
wipe exterior surfaces with a damp cloth. Never use any
cleaners or solvents.
4. Do not use this product in a high humidity environment
or near water,for example a wet basement,wet bar,or swim-
ming pool.
5. If the electrical service is subject to frequent sags, spikes,
and brownouts, a power conditioner designed for use with
high fidelity equipment may be employed to protect the
Sonamp 1230.
SYSTEM CONFIGURATION
Read Getting The Most From Your Sonamp 1230 and plan your
installation configuration. Due to the flexibility of the Sonamp
1230,the installation should be carefully planned to avoid errors.
Start by drawing a diagram of the system,like the examples in this
manual.Plan the settings and connections to achieve your objective.
Verify that you have all of the parts and tools required for the
installation:
• High fidelity interconnect cables such as Sonance Silver
MediaLinQ OFC Interconnects.
• Speaker wires.These may be unterminated (tinned bare wire at
connections) or spade, banana, or pin connectors. Gold plated
connectors are preferred to resist oxidation.
• LS1 and LR1 balanced line-level sender and receiver
(optional).If the amplifier is placed more than 20 feet from the
source or preamplifier, the balanced sender and receiver pro-
vide a way to send low level audio signals long distances and
near sources of noise interference without introducing noise or
suffering high frequency roll-off (See Fig.6 for example).
INSTALLATION
Unpacking
Save the carton and polystyrene inserts for future safe transport
in case the amplifier is moved or the unit requires shipping
for repair.
Before proceeding with installation, locate the serial number
on the real panel of the unit and note it here for future reference :
S/N:_________________________________________
Placement
CAUTION: Do not attempt to lift the Sonamp 1230
without assistance. Improper lifting of this 35 lb. unit can cause
personal injury.
Place the Sonamp® 1230 on a level surface, in an upright
position, out of direct sunlight and away from windows through
which rain may enter.NOTE:The amplifier must always rest on its
four feet to allow ventilation or it will sustain damage.
Situate the amplifier away from heat sources such as hot air
ducts or radiators. Be sure that the amplifier is adequately
ventilated by convection or suitable cabinet fans. CAUTION:
The Sonamp® 1230 requires four inches of clearance on the top
and all sides. Never place any object on or against the
amplifier. Never operate the amplifier on a carpeted surface as
this will compromise ventilation. When the amplifier is
installed in any cabinet, the front or back must be open during
operation. Alternately, install fans in the cabinet to assure
continuous ventilation.
Power Connection
The Sonamp® 1230 uses a 14 gauge EIA standard 120 volt
grounded power cable (provided). Due to the power require-
ment of this amplifier,it is not advised that this cable be replaced
with another of unknown quality.Connect the power cable to a 15
amp or 20 amp grounded wall outlet.Never attempt to operate the
amplifier from the accessory outlet of another component.
Sensitive source components should be isolated from the
Sonamp® 1230 with appropriate power conditioning to
minimize hum from the amplifier’s power supply.
Speaker Connection
Always turn off power and unplug the amplifier before making
source signal or speaker connections.
Use quality speaker wire such as Sonance Silver or Gold
