I-PAM
Digital Multi Channel Amplifier Module
The I-PAM is an essential component of VARIZONE’s Digital Speaker System (DSS) bus.
It is a small distributed 2-channel Class D amplifier module with integrated control functionality.
The I-PAM allows above-ceiling mounting in close
proximity to the loudspeaker (I-PAM box) or even
integration into the speaker enclosure (I-PAM bulk).
The I-PAM receives power and 8 different audio signals
in addition to bi-directional control data from the Digital Speaker System (DSS) bus. It selects and amplifies two
audio channels from the bus for play-out via the connected speakers.
In addition, trigger inputs and outputs, and control interfaces on the
I-PAM, allow building a complete
distributed control network.
I-PAM features at a glance:
- Allows installation of up to 2 speakers
- Power supply via speaker line bus
- Output power: 2 x 6 watt
- Individual selection of audio channels from the DSS bus
- Built-in volume control of the selected audio signal
- Control interface for connection of remote controls
- 2 trigger inputs and 2 trigger outputs centrally controlled (e.g. emergency strobe lights or alarm buttons)
- Individual monitoring of the connected speakers via a 20kHz pilot tone
- Individual adjustment and monitoring of all installed I-PAMs via the VAB1 Controller
