UP 2321
Power Amplifier
UP 2321 ia a 320 W power amplifier designed for the transmission of announcements and musical programmes. The amplifier is equipped with a (mic / line) Main Input on either removable connector or XLR or RJ 45 and an Auxiliary Input for music sources (e.g. CD players, tuners, etc.). The amplifier output is available either for low impedance loudspeakers or 100 – 70 V constant voltage line. The amplifier is Class D with switching power supply; the overall weight is extremely reduced plus it offers a wide audio bandwidth quality.
