All input filters are 100% analog, among the fastest ever offered in a subwoofer. At the center is the acclaimed High Level Input, which connects directly to the speaker outputs of the main amplifier. Rather than drawing power, it transmits the full sonic signature of the system, allowing REL to integrate seamlessly with speakers—a quality praised by reviewers for decades.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWhen High Level isn’t feasible, the low-level input uses the same analog filter circuit, available via RCA and XLR connections, to deliver the speed, naturalness, and cohesion REL is known for.
