POWER CABLE

Permanently attached power cable with CEE 7/7 mains plug.
11
LINE INPUT IN CH 1–4
Balanced line inputs for channels 1 to 4 with 3-pin XLR sockets (female). Control by unbalanced cables is also possible but balanced signal
transmission is preferable due to the higher level of noise immunity.
Balanced pin connections: Pin 1 = shield, Pin 2 = +, Pin 3 = -
Unbalanced pin connections: Pin 1 & 3 = shield & -, Pin 2 = +
12
LINK CH 1–4
Balanced line outputs for channels 1 to 4 with 3-pin XLR sockets (male). The sockets for the CH 1 to 4 line outputs are connected in parallel
with the relevant input sockets IN CH 1 to 4.
13
OUTPUT CH A - CH D
SpeakON speaker outputs for channels A to D. To avoid damage to the equipment, make sure that the total impedance of the connected
speakers is at least 2 ohms.
Socket assignment OUT CH A/B: plus 1 & minus 1 = CH A / plus 2 & minus 2 = CH B
Socket assignment OUT CH B: plus 1 & minus 1 = CH B
Socket assignment OUT CH C/D: plus 1 & minus 1 = CH C / plus 2 & minus 2 = CH D
Socket assignment OUT CH D: plus 1 & minus 1 = CH D
In Bridge mode, the channel pairs CH A / CH B and CH C / CH D are linked to create higher-performance mono amps. The line input for Bridge
A/B is XLR socket IN CH 1, for Bridge C/D the line input is XLR socket IN CH 3. In Bridge mode, the minimum impedance for connected speakers
is 4 ohms.
Socket assignment OUT CH A/B BRD: plus 1 & minus 2
Socket assignment OUT CH C/D BRD: plus 1 & minus 2

ETHERNET
The Ethernet interface enables management and remote control of the DSP amp via LD Systems OCS software (can be downloaded free of
charge on the product page at WWW.LD-SYSTEMS.COM).
15
DANTE™ (DSP 44 K only)
The Dante™ interface allows loss-free and interference-free transmission of digital audio signals over long distances using commonly
available CAT5e (or better) Ethernet cables (Primary = Network 1, Secondary = Network 2).
16
HOUSING FAN
In order to avoid overheating of the device, ensure that the fan is not covered and that air can circulate freely.
