Product Features

■ A class-D amplifier capable of producing 120W/240W/360W/480W output is adopted.
    (PAM-312: 120W, PAM-324: 240W, PAM-336: 360W, PAM-348: 480W)
■ The amplifier produces high-impedance output. (100V/70V)
■ It supports various input types including 3 MIC/LINEs, 3 LINEs, a Stereo input, and a TEL IN.
■ Each channel has its own volume control.
■ A mixed signal output (MIX OUT) is provided.
■ A TONE (BASS/TREBLE) function is adopted.
■ 5-speaker selection switches are provided.
■ External MUTE, External Chime, and EM Contact Closure functions are provided.
■ A 4-Tone Chime function is provided.
■ An Output Level Indicator is provided.
■ A Priority Broadcast (PRIORITY) function is provided. The priority is as follows:
■ EM > TEL IN > INPUT 1/RM-05A, INPUT 2, CHIME > INPUT 3/4/5/6, EXT IN, PAM Module
■ INPUT 1 and INPUT 2 can turn on/off the PRIORITY function.
