Command precise volume in up to four independent zones on your boat or RV! This universal zone control distributes a stereo RCA signal from your media center/source unit to as many as four independent stereo RCA outputs. Max output means cleaner, better sound The built-in line driver delivers clean signal up to 8-volts to each channel so your amplifier is getting the cleanest signal possible. Higher input voltage into your amplifier allows you to set your gains lower and keep system noise down for the cleanest sound possible! Works with most any amp KXMARLC is compatible with any amplifier that features pre-amp level inputs, and it’s perfect for large, multi-amplifier systems where you want ultimate control over the boat or vehicle’s volume levels. Think of all the uses We believe you will find lots of ways to incorporate KXMARLC – adding level control in an enclosed cabin, independently controlling the level of your tower speakers on your wake boat, and many others not listed here. The point is… it’s flexible in terms of application. Features! Comes with a hide-away processor unit and a half-DIN remote zone controller The preamp section allows for lower gain settings, increased noise rejection, and better sound The large knobs provide the easiest way of adjusting individual zone level volumes Includes amp remote turn-on output Includes customizable labels for naming your zones Comes with all installation hardware, and the hardware required to surface- or flush-mount the remote zone controller Specifications Rated Output Per Channel, all channels driven (1kHz,14.4v DC, THD < 1%): 8v Frequency Response [Hz] (± 1dB): 20-20k Signal-to-Noise Ratio @ Rated Power [dB]: 100 Input Sensitivity (VAC): 4.0 - 0.125 Input Impedance [Ohm]: 10k Output Impedance [Ohm]: 100k
