• Rack-mounting amps-preamps with a power of 120/340/480W, 100V/70V line or low impedance for PAM-120A.
• They are fitted with 6 preamplifiers including a bass/midrange/ treble adjustment and a separate adjustment of input level (microphone or line).
• A key located on all inputs allows operation of a Phantom power supply to connect an electret microphone on each input.
• A key located on the first two inputs enables to give priority to such inputs by fading.
• These devices are also fitted with a 4-tone chime that can be remote controlled with a microphone station, a master input and an L/S line selector.
• For the sound quality to be refined, keys located at the front panel enable to adjust the level of each input individually, the "general” bass/treble level as well as the general level.
Features:
• 6 Mic/line inputs (3 pin XLR)
• 2 Module option slots
• Link input (¼” jack)
• Amp input (¼” jack)
• Pre amp out (¼” jack)
• External chime (screw terminal)
• Zone mic interface (15 pin D-type)
• External mute (screw terminal)
• Individual EQ per input channel
• Individual phantom power (per mic input)
• Priority mic 1, mic 2 (switchable)
• 5 Zone loudspeaker selector
• Bar graph VU metre
• Optional 19” rack kit (BKT-PAM)
• 3U high
• Emergency message facility
- MODULAR DESIGN
Optional modules can be installed in multiple configurations for convenience and ease of use. Choose the PAM-CDA (Compact Disc), PAM-T (AM/FM Tuner) or PAM-D (Cassette Deck) modules to expand the PAM-120A/340A/480Aʼs audio capabilities.
- INDIVIDUAL INPUT GAIN CONTROLS
Rear-panel gain controls for each input channel for total control of individual levels.
- SPEAKER SELECT
Six speaker select switches enable you to select any combination of up to five speakers.
- SELECTABLE PRIORITY MUTING
Switchable audio signal priority for Channels 1 and 2, Chime and Telephone input over other input sources.
- REMOTE CONTROL INPUT (only PAM-340A/480A)
Individual speaker zones can be selected and chime can be operated by wired remote control.
- ANNOUNCEMENT CHIME
Convenient four-tone chime for use with announcements.
- EM(EMERGENCY) - OPTIONAL EMERGENCY VOICE IC (only PAM-340A/480A)
When EM switch is pressed in emergencies, EM broadcasting stored in VOICE IC is outputted.
