Introduction      Technical Specification    Installation


The SGA-40 is manufactured in the 50mm euro format. It is supplied with a UK one gang white mounting frame and other suitable mounting frames are available in a wide range of finishes from iKON AVS as well as multiple switch plate manufacturers.
The SGA-40 fits a standard UK format single back box and requires only a 35mm depth, and it will also fit the single DIN back box as used in the European market.


The SGA-40 uses an 86% efficient class D design and has a RMS* output of 20 watts per channel into 8 Ohms when powered from an 18V power supply or 10 watts when powered by the included 12V power supply, and as most quality loudspeakers are 8 Ohms, maximum efficiency is assured.

It is fitted with two rear inputs on screw terminals for permanent connections and two 3.5mm stereo jack on the front panel for other sources making the SGA-40 easy to install & use.

Introduction      Technical Specification     Installation
Warning        Disconnect power and unplug the unit from the power source before installing or removing.

The SGA-40 is designed to fit a standard UK back box with a minimum depth of 35mm. It will fit most metal recessed, surface metal & plastic as well as dry liner and dado mounting boxes. If possible a 47mm deep box is to be preferred as this makes wiring easier.
Cable entry into the box can be from any combination of the knockouts but it is recommended that the audio input cables are kept separate from both the DC and speaker cables if at all possible. Close proximity will cause no damage but could induce noise.

Power  

The amplifier is DC powered and this should be fed from either the supplied power supply or suitable alternative.
A mains power connection will be required for the power supply achieved by plugging the supplied cable into an adjacent socket. If the cable needs extending or connecting into a fused spur then the services of a qualified electrician to carry out the connection is recommended.
Please note that for UK installations in domestic premises connection by a part ‘P’ registered electrician is mandatory.

The power supply is connected to the 12-18V DC screw terminals on the rear PCB.  The moulded DC plug on the power supply needs cutting off and the cables stripping approximately 6mm to allow connection to the screw terminals on the amplifier. The cable with the white trace line is +V unless indicated otherwise on the PSU’s box.
Please ensure correct polarity when connecting the DC power supply
Environmental

The SGA-40 amplifier is not IP rated and should not be used in Bathrooms, outdoors or similar damp environments unless provided with additional protection of suitable IP rating.
