The LD Systems PAM is a high-quality gooseneck table microphone that can be used for general announcements over permanently installed public address systems in retail stores, schools, warehouses or other public areas. Three announcement modes are available via the central, configurable push button: Push-to-Talk, Push-to-Mute, Latch On/OFF. The integrated LED microphone symbol indicates whether the PAM is active, i.e. in use.
PAM includes a robust desktop base, which features non-slip long rubber feet on the underside of the housing to ensure a secure stand at all times and minimise the effects of knocks, vibration and structure-borne noise on the microphone.
In addition to the balanced audio output, the PAM also features a hard-wired contact closure output that allows priority mutes to be triggered in mixer amplifiers and zone mixers via a MOSFET switch.
This makes the paging table microphone perfect for use in combination with the LD Systems mixing amplifiers of the IMA series or the ZONE mixers. At the same time, it is compatible with all third-party devices that have a microphone and contact closure input. For optimal signal transmission, the PAM sends signals with a gain of +5 dB. This also helps to solve sound loss issues with long cable runs.
The integrated low-cut filter attenuates frequencies below 100 Hz and ensures transparent speech announcements without annoying, low-frequency background noise, which is usually caused by humming or vibrations during tabletop operation.
