3.6Configuring the XLogic Mic Amp

There are a number of internal link settings, most of which should not normally require adjustment – see Appendix A for a full listing. Those links that change the operation of the unit are described below.

Setting the Channel Displays

If the unit is connected to an XL 9000 console the 5 address bits on the 25 way ‘D’ type Audio/Control connector are set on the console channel bus card so that the channel displays automatically show the channels the unit is connected to.

When controlled locally or from the XLogic Mic Amp Remote control unit, the channel displays can be set by adjusting a rotary switch that is accessible through the lid of the case – see the drawing to the right. The rotary switch has 16 positions, allowing the front panel display to show channel numbers in the range 1 to 60. To display channel numbers above 60 the internal jumper LK5 (screened BIT 5) should be moved to position ‘b’.

To perform this adjustment, make a note of the front panel displays, power-down the unit and insert a thin flat bladed screwdriver. Referring to both the screening on the top cover and to Table 1. opposite, set the switch as required. Remove the screwdriver and re-apply power.

Note that the rotary switch position is ignored if the unit is connected to an XL 9000 console but that LK5 will always increase the displayed number by 60 when set to position ‘b’.

Note. It is recommended that this adjustment is not performed with power applied as a mis-placed screwdriver can cause damage to the XLogic Mic Amp!

Changing the Remote +48V and Phase Switch Functions

If the unit is to be controlled from an XLogic Mic Amp Remote control unit then the phantom power selection is normally made from the Mic Amp front panel and phase is remote controlled. If the unit is to be controlled from an XL 9000 then phase is normally controlled from the Mic Amp front panel and phantom power is controlled from the console. This selection is automatic – the unit detects if any of the address inputs on the Audio/Control 25 way ‘D’ type connector are connected to ground and selects ‘XL’ mode accordingly. The selection can be reversed by moving the internal jumper LK6 (screened PHAS/PHAN) to position ‘b’.
