PRECAUTIONS
The following precautions should be taken when operating the
equipment.
GENERAL PRECAUTIONS
When setting the equipment ensure that:
the ventilation holes are not covered
air is allowed to circulate freely around the equipment
it is on a vibration free-surface
— it will not be exposed to interference from an external source
it will not be exposed to excessive heat, cold, moisture or
dust
it will not be exposed to direct sunlight
it will not be exposed to electrostatic discharges
Never place heavy objects on the equipment.
If a foreign body or water does enter the equipment, contact
your nearest dealer or service centre.
Do not pull out the plug by pulling on the mains lead, hold the
plug.
It is advisable when leaving the house, or during a thunder-
storm, to disconnect the equipment from the mains supply.
SM-17SA
The SM-17SA is a power amp that can be switched between
stereo and monaural operation (BTL operation). In addition,
the SM-17SA is equipped with a line amp that is compatible
with fast BTL amps. This capability makes an even more ad-
vanced audio system possible by allowing you to connect an-
other power amp to your system so that you can implement bi-
amp drive for the speaker system.

CONNECTIONS OF AMPLIFIER
Connect the output jacks of your pre amplifier to the INPUT jacks
Connection of speaker systems
Each of the speaker systems connected to this unit should have a impedance between 4 and 16 ohm. Connecting a speaker
system with a lower impedance than 4 ohm may activate the protection circuitry during sound reproduction.
The output terminals are provided with the positive (
:Red) and negative ( : White) polarity, and the input terminal of each
speaker system also has the polarity (
and ). Be sure to connect the terminals with the identical polarity.
Caution:
If you will be using two speaker systems, or you will be using the SM-17SA in BTL mode, use speaker systems that have an
impedance of at least 8 ohm. If you connect a speaker system that has an impedance of less than 8 ohm, the SM-17SA’s
protective circuitry may be worked, making the amplifier incapable of normal stereo playback.
