You will find detailed information in the table on page 11. - Page 9 If you choose „Always On“, the DA 428 is always on. That means after apply power supply connection the unit is automatically on and ready to play (the “lock function” can be active!). If you choose „Last State“- mode, the DA 428 will always start in the last state of operating after power cycle the unit.

Page 11: Routing Of Input Channels
You will drive a passively channelled PA system with two separately driven monitor systems (passive) with your DA 428. The input signal fort the PA is digital and the monitor systems are driven with two separately analogue input signals. Please plug in the digital input signal to input A of DA 428 and the monitor signals to input C + D. -

This center-cluster consists also of 4 PANO Line Array elements. Please plug in the left input signal to input A and the right input signal to input B of the first DA 428. Now you have to route output A – output C of the first DA 428 to „A/d1(L)“ = left audio signal for the left 6 elements (connect always two together). -

Press for 1 second the encoder A / B / C or D to mute the channel. A repeated pressing of the particular encoder causes the deactivation of the „mute“-function (see display). If the „mute“- function was activated (before switching off the DA 428), the „mute“- function is after switching on the DA 428 again still activated. -
