The Power, Signal & Clip indicator LED’s monitor the proper working of the integrated amplifier. The optional VC4008 wall volume controller has to be connected to the remote RJ45 connection. This makes it possible to control the general volume level. The volume of the satellite channels can be controlled using the ‘Volume Satellite’ control knob. The volume of the subwoofer channel can be controlled using the ‘Volume Subwoofer’ control knob. The balanced input connections are made by means of 3-pin euro terminal blocks. The amplified satellite output connections are made by means of 4-pin euro terminal blocks. This allows you to connect two satellite speakers on every output channel. Due to the high efficiency of the integrated class H amplifier, the SX408A is completely passively cooled by means of the large ribbed aluminium heatsink on the back.
