2 - Additionally Channel A Speakon connector carries Channel B output on Pins +2 & -2 to allow easy bi-amping or
bridged operation.
HOT Pin +2
COLD Pin -2
CONFIGURATION 2 DOES NOT APPLY TO CT 160
(See also Bridged operation)
NOTE: 1. There must be no shared connections between channels
.
NOTE: 2.
Because the currents involved are very high, the speaker cables should conform to the following
minimum requirements, otherwise the losses will cause the cables to get hot and audio power will
be reduced:
NOTE
: 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.
BRIDGED (MONO) OPERATION (DT 450)
Supply the signal to Channel A input only & push in the rear panel switch marked 'Bridged Mono'
Use Channel A Output Speakon connector and connect as follows:
HOT Pin +2
COLD Pin -1
BRIDGED (MONO) OPERATION (CT 160)
Use centre Speakon connector marked ‘BRIDGED’ and connect as follows:
HOT Pin +1
(Channel C - IN PHASE)
COLD Pin -1
(Channel D - OUT OF PHASE)
When operating in bridged mode, the minimum impedances are doubled. The minimum load in bridged
mode is: DT 450: 4 ohms, CT 160: (Ch C & D only): 4 ohms.
LINK SOCKET
Each channel is provided with a 3-pin XLR connector marked ‘LINK’ which allows the input signal to be linked to
further amplifiers etc. The connections are the same as for the input XLR.
OPERATION
Read all documentation before operating your equipment and retain all documentation for future reference.
Do not spill water or other liquids into or on the unit and do not operate the unit while standing in liquid.
Do not block fan intake or rear ventilation outlets or operate the unit in an environment which could impede the free
flow of air around the unit.
If the unit is used in an extremely dusty or smoky environment, it should be cleaned of any collected debris at regular
intervals. (See Maintenance section.)
