Delta Series – Non-DSP Models Operating Instructions
Page 13
When operating the amplifier into loads of less than 4 Ohms, be aware that the current
capacity of the speaker cables will need to be increased above the values quoted here.
Do not connect the inputs/outputs to any other voltage source such as a battery, mains source
or power supply, regardless of whether the amplifier is turned on or off.
Do not run the output of any amplifier channel back into another channel’s input and do not
parallel or series-connect an amplifier output with any other amplifier output.
Connecting To Your Amplifier: Bridged (Mono) Operation (excl. Delta 120)
Pairs of channels may be independently bridged — channel pair 1+2, and/or channel pair 3+4.
The method is the same for both channel pairs:
Select the required bridged mode through the front panel MENU system (see page

for more information).
Use Channel 1 or 3’s Output Speakon connector and connect as follows:
Pin 2+: Hot
Pin 1-: Cold
When operating in bridged mode, the minimum impedances are doubled.
The minimum load in bridged mode is 4 ohms.
Bridging is NOT possible on the Delta 120.
