Highlights
- Designed to amplify the audio of an ASLT subscriber line
- Can be used standalone (speaker only), or in combination with a station to amplify the speaker signal
- Connects directly to the ASLT subscriber line
- Provides 20 Watt into 4 Ohm, 12 Watt into 8 Ohm, or 6 Watt into 20 Ohm
- Powered by 24VAC transformer or 24-36VDC power supply
Connectors and Switches
WK20 and IP Stations
The amplifier can also be used with IP stations, connecting the line output of the IP station to the input of amplifier. Note that when used with IP stations the output power will be less than specified in the table below, because the input of the amplifier is designed for ASLT line levels (2.2 volt nominal, max 8 volts) and the line level from the IP stations is 0dBm signal (approx. 0.77 volts).
