Control pushbutton
The DSP MINI MK2 provides 10 internal memory
locations for sound setups. The
Control pushbutton
allows the user to switch between two memory po-
sitions. These can be defined in the DSP PC-Tool.
1. Setup switch: Press
Control pushbutton
for 1 sec-
ond. The memory locations one and two are defined
by default. Switching is indicated by a single red
flash of the
Status LED
. Alternatively, the optional
URC.3 remote control can be used for switching.
To switch between all internal memory locations,
optional accessories like the DIRECTOR display
remote control, CONDUCTOR or WIFI CONTROL
are required.
2. Device reset:
Press pushbutton for five seconds.
This completely erases the internal memory and is
indicated by a continuous red glowing and constant
green flashing of the
Status LED
.
Attention:
After erasing the setups from memo-
ry the DSP MINI MK2 will not reproduce any au-
dio output until the device is updated via the DSP
PC-Tool software.

Status LED
The
Status LED
indicates the operating mode of the
signal processor and of its memory.
Green:
DSP is ready for operation.
Orange:
Power Save Mode is active.

Protection Mode is active. This may have dif-
ferent root causes. The DSP MINI MK2 is equipped
with protection circuits against over- and under-
voltage as well as overheating. Please check for
connecting failures such as short-circuits or other
wrong connections.
If the DSP is overheated the internal temperature
protection switches off the remote and signal output
until it reaches a safe temperature level again.
