California Prop 65 Warning
For CA Residents Only.
California Proposition 65 Warning
Proposition 65, officially the Safe Drinking Water and Toxic Enforcement Act of 1986, is a law that requires warnings be provided to California consumers when they might be exposed to chemicals identified by California as causing cancer or reproductive toxicity. The warnings are intended to help California consumers make informed decisions about their exposures to these chemicals from the products they use. The California Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program and publishes the listed chemicals, which includes more that 850 chemicals. In August 2016, OEHHA adopted new regulations, effective on August 30, 2018, which change the information required in Proposition 65 warnings.
• WARNING: Some cable, plastic, and metal products may contain chemicals known to the state of CA to cause cancer, birth defects, or other reproductive harm.

Impedance Matching Volume Control 75W Rotary w/White Ivory Almond Knobs Inserts Plates Screws
Product Information
the ZL75RWIA is a High quality stereo autoformer, multiple speaker, impedance matching, 12-step rotary knob, make before break switching volume control
It is important to match your amplifier impedance to your speakers. With ZLoc Volume controls by Current Audio, you now can make virtually any amp/speaker combination work well together.
The ZLoc design uses an autoformer that multiplies the speaker impedance to present an optimum balanced load to the amplifier for maximum transfer of power with no signal loss.
As you turn down the volume level the impedance level goes down and the current capability goes up. This preserves low level details, tone and dynamic changes. Our design does not attenuate by wasting energy as heat.
There are 12 separate volume levels controlled by the silent acting knob on the “decora†style plate. The lowest setting is OFF. At the maximum setting the load follows the amplifier signal. The volume is reduced in -3db steps by doubling the resistance of the load in each step from max to OFF.
Jumpers on the ZL75RWIA circuit board allow simultaneous connection of up to eight pairs of speakers to your amplifier. Or connect one ZLoc to each pair of speakers for individual control.
Wire connection is made by two (2) locking detachable positive screw down terminals. The Input is for connection to the amplifier and the output terminal is for connection to the speakers.
The terminals can accommodate up to 16 gauge wire. ZLoc fits a standard 18 cubic inch single gang electrical box or open back box.
White, Ivory and Almond faceplates and knobs are included.
