Balanced and Unbalanced Connections You wonÕt have to worry about using the PA-150 today Ñ or tomorrow. With both balanced and unbalanced connectors, it will easily integrate into any studio. The back panel inputs are optimized for +4 dBm and -10 dBV levels, minimizing gain staging to a single front panel sensitivity control. Also on the rear panel, is a stereo/BTL mode selector switch that enables you to take advantage of the PA-150Õs Dual Power Design. That means it can be used to pump out stereo or mono signals. Of course, solid speaker wire terminals are well labeled and make it easy to set up for bridged mono or stereo use. Setup is quick and simple. You Need Power, Performance and Protection The PA-150 sounds great and delivers 150W per channel at 4 ohms or 115W per channel at 8 ohms. And with an extremely flat frequency response of 20Hz-20kHz at less than .08% THD, it delivers a clean, transparent signal perfect for recording studio monitoring applications. And while the PA-150 packs enormous headroom, youÕll be pleased to know that it will warn you if your signals get too hot with its bright LED clip indicators for each channel. ¥ Stereo/BTL mode select switch ¥ Balanced and unbalanced inputs ¥ 150W per channel at 4 ohms ¥ 115W per channel at 8 ohms ¥ Accepts balanced XLR or 1/4 jacks ¥ Connect your speaker wires for stereo or bridged mono use ¥ Power indicator turns red whenever the PA-150 is protecting PA-150 DUAL POWER AMPLIFIER page 1 of 2 Every personal, project or major recording studio needs power.
