An analog audio source may be connected to either the mono balanced terminal block input or to the unbalanced mini-jack which sums the left and right channels to mono. Amplifier gain is set by the installer using a rear-panel single-turn potentiometer with an associated dual-led vu meter calibrated to 20 db below maximum power output. The sf-pa50a is equipped with an internal vca for setting the amplifier output level. A detachable terminal block provides for the connection of an external 10 k potentiometer or a 0 to 10 vdc control voltage. Rdl remote controls are available to provide single-turn multi-turn rotary encoder or pushbutton ramp or fixed level selection user level control. Vca control insures long term noise-free level adjustment. ... Brand: Radio Design Labs Delivery Time: Next Day
