RJ45 connector. This all makes the SX408A a simple but complete solution for a wide variation of fixed audio installations. The balanced input connections are just as the satellite speaker output connections made with euro block terminal connectors. -
Page 5: Environment
Chapter Environment Do not place this unit in an enclosed environment such as a bookshelf or closet. Ensure that there is adequate ventilation to cool the unit. Do not place the unit in environments which contain high levels of dust, heat, moisture or vibration. -
Page 6: Safety Requirements
Safety Requirements Always handle the unit with care. Only use a grounded socket outlet and a power cord with grounding plug to plug in the unit. This unit is not a toy. It should not be operated by children. Do not stick objects through the openings. Do not open the unit (risk for electrical shock). -

Page 8: Rear Panel Description
This LED illuminates whenever there is a signal present at the input connectors. Clip LED: The SX408A has a built-in limiter that prevents the outputs from overdriving. When the Clip LED lights up frequently, the level must be reduced, because the maximum power is reached. -

3) Satellite volume control With this dial, the output level of the satellite channels can be set. The attenuation of the signal can be set between 0dB and -50dB by rotating the dial. 4) Subwoofer volume control With this dial, the output level of the subwoofer channel can be set. The attenuation of the signal can be set between 0dB and -50dB by rotating the dial. -
Page 10: Satellite Output Connections
Balanced: Unbalanced: Shield Sleeve 6) Satellite output connections On these euro terminal output connections is the amplified output signal present with a frequency above 120Hz. Connect these to the satellite speakers. A total of 4 speakers with an impedance of 8 Ohm can be connected to these output connections. The total impedance load should not be lower than 4 Ohms. -
Page 11: Power Switch
The input connection is performed using IEC power connectors. The SX408A is factory default set to be used on 220 – 240 Volt AC mains networks. But it can be switched to be used on 110 – 120 Volt AC mains networks. -

FESTA 400 4 x WX502 + SX408A Make sure that the WX502 loudspeakers which will be used in combination with the SX408A are set to 8 Ohm impedance. This can be done by turning the power tap adjustment screw on the rear of the speaker to 8 Ohm. -
Page 14: Congress 400
These switches are meant to convert the speaker for use in 100V or low impedance applications. Set these switches to Low Impedance to be used in combination to the SX408A. After this is done, the speaker can be assembled again as it was originally. -
