The CL-RLC is a true, active level control preamplifier which can be used for subwoofer level control or as an audiophile-grade, full-range volume control. The CL-RLC's differential-balanced inputs minimize the likelihood of noise, while its very healthy preamp design delivers up to 7.5 VRMS of unclipped output to your amplifier. Unlike cheap, passive line-level controls, no signal passes through the CL-RLC's control cable and knob. Instead, the control knob only sends volume level signals to the preamp circuit in order to maximize fidelity and minimize the possibility of noise.
Subwoofer Level: By inserting the CL-RLC in-line with any signal feeding a subwoofer amplifier you can control the subwoofer level from the front of the vehicle using the supplied control knob. Unlike the RBC-1, which is an EQ boost controller, this is a true level control for the subwoofer amplifier. Another important feature is a buffered pass-through connection so that you can also pass signal along (without volume control) to a satellite amplifier from the same input channels.
Full-Range Volume Control: Since the CL-RLC uses top-quality active circuitry, its application is not just limited to subwoofer duty. It can be used whenever and wherever you want to have volume control over any line-level signal. For example, you can use it to control a center-channel level, rear channel levels, or even the level of an iPod input directly to an amplifier. The possibilities are endless and will enable very interesting things to be accomplished in a wide variety of systems.
