Example 2. One X-AS100 with a pair of X-A50s or X-A200s

In our second example, a pair of X-A200s are used to drive the bass unit (woofer) of each channel whilst an X-AS100 is used to drive the treble unit (tweeter) of each channel. The X-AS100 is connected to a preamp in the normal way with a pair of phono leads. Then the line input of each X-A200 (or X-A50) is connected to a 'Loop Out' of the X-AS100 with another set of phono leads. The X-AS100's Mono/Stereo button must be out for stereo operation. The X-A200s in this example drive the left and right bass units whilst the X-AS100 drives the left and right tweeter.

EXTERNAL POWER SUPPLY

We recommend that the Power Supply Unit be positioned on the floor as far away from the X-AS100 as possible. This ensures that there is no magnetic interaction between the X-AS100 and the power supply unit thus giving best performance.

The X-AS100 has been designed so that it may be left switched on indefinately if desired.

WARNING - Heat

When in use the X-AS100 gives off heat from its casework.

Never put anything on top of your X-AS100.

Always ensure that the unit has adequate ventilation.
