3 x Performance analysis charts

1 x Detachable AC power cord

Placing Your

SX25i

The SX25i should generally be placed close to your source

equipment, thus keeping interconnect cabling between the SX25i

and associated components as short as practical. This will reduce

the systems susceptibility to radio frequency interference and the

negative effects associated with long cables.

Ventilation

Requirements

The SX25i is a convection cooled amplifier. For optimal

performance, the unit MUST receive adequate ventilation.

 Please do not cover the product with a cloth or similar.

 Please do not mount the SX25i directly onto carpeted

surfaces.

In the event that the SX25i is to be incorporated into custom

cabinetry, please refer to the dimensional information provided in

the Physical Dimensions section of the manual (Chapter 12).

Note: Please take all necessary steps to ensure that the unit

receives adequate ventilation

2 Instant Install

If you are like us, the first thing you will want to do is to play

your favourite piece of music through your new SX25i. The

following instructions are written to enable you to achieve this as

quickly as possible. These are not comprehensive instructions,

but are designed to enable you to play music now!

Note: Please take the time to read the SX25i manual thoroughly

as it incorporates many features, which will enhance its

operation.

Placement

The SX25i is a convection cooled amplifier and best results will

be achieved when placed on a solid surface with adequate

ventilation. DO NOT place on a carpeted floor or cover the

amplifier!

Place the SX25i close or near the source component in order to

make as short a connection as possible.

Turn off associated components

This minimises the potential to damage any other components

when connecting your SX25i into the system.

Connect source to SX25i

Connect the audio output from the source component to the

inputs at the rear of the SX25i. Refer to Chapter 4 for Rear Panel

information.

Connect loud speaker cables to SX25i

Connect your left and right channel loudspeaker leads to the

bindng posts at the rear of the amplifier. Refer to Chapter 4 for

Rear Panel information.

Note: Make sure the nominal impedance of the loudspeakers is

not lower than 2Ω.

Switch on SX25i

Caution! Prior to connecting the AC mains, please check the voltage

label on the rear panel to ensure that your unit conforms to

the power supply in your area. Never attempt to connect

the unit to the incorrect voltage.

Insert the power cord supplied into the rear of the SX25i and into

the wall. Switch on the socket at the wall and turn on the power

of the SX25i by setting the power switch down.

Switch on source component

Power up your source component and start your favourite

recording. Slowly increase the SX25i volume to achieve a

comfortable listening level.

CONGRATULATIONS!

Now that you have achieved your first objective, sit back, relax

and please read the rest of the manual at your own pace in your

favourite armchair whilst sipping a hot cup of coffee. You’ll find

the whole experience much more pleasurable whilst listening to

music.
