Recommended Amplification
DSP and Amplifier Channels
Two independent amplifier channels are required, with one amplifier channel driving each 4 Ω woofer separately. One shared DSP processing path may feed both channels when identical processing is required; two independent DSP channels may be used for individual control, monitoring, or limiting.
Minimum Recommended Amplifier Capability
Per amplifier channel: 89 Vrms 126 Vpk 22.5 Arms Equivalent to approximately 2,000 W into 4 Ω Complete system: two channels, approximately 2,000 W into 4 Ω each.
Recommended ASCENDO Electronics
DSP4-6602, DSP4-10K2, or DSP-4D + AIA2-10K2 IS
Configuration Notes
The two drivers should not normally be connected in parallel as a 2 Ω load. Independent drive preserves greater effective electrical damping, reduces the influence of cable resistance, avoids the higher current demand of a 2 Ω load, and allows correct individual RMS and peak limiting. Correct RMS and peak limiter settings must be applied to each amplifier channel.
