What it does
The Analog Subwoofer Integration Crossover gives a powered subwoofer a controlled low-pass feed from a compatible stereo line signal. A separate high-pass main output is a proposed option, subject to measurement and system testing. Clear controls will document frequency and level. It cannot automatically align a subwoofer to a room, correct acoustic problems, or supply speaker-level power.
Required but not included
- compatible line-level source/preamp, powered subwoofer with suitable input, main amp/powered speakers and cables. Passive subwoofers require a separate amplifier.
Included
- Base low-pass crossover and approved low-voltage supply. High-pass main output requires a separately priced accepted configuration.
What it does not do
- Base scope is a low-pass feed for a powered subwoofer. High-pass mains require a separately priced configuration. No room alignment or speaker-level power.
