The discrete wiring mode reduces the number of cables required to wire a subwoofer system to a minimum, however
this is at the expense of flexibility. Since multiple enclosures are powered and processed by the same pair of amplifier
channels, DSP parameters such as presets or delay can only be applied to groups of subwoofers, not individual sub-
woofers. For optimum flexibility, one subwoofer per amplifier channel (parallel wiring mode) is recommended since it
is more convenient to implement cardioid subwoofer configurations and Electronic Delay Steering (EDS). Parallel mode
operation and adapter cable accessories are discussed in the following sections.
I-Tech 4x3500HD Standard Wiring (Discrete Mode):
The same wiring configuration can be achieved with the Crown 4x3500HD amplifier by using 2 x NL4 cables and 2 x NL4
jumpers as shown below:
NL4 Wiring CH1/2
Pin 1 ± Channel 1
Pin 2 ± Channel 2
NL4 Wiring CH3/4
Pin 1 ± Channel 3
