3-4 Channel 35W-60W Power Amplifier Description:
The 3-4 Channel 35W-60W Power Amplifier works as a high value mixer-amplifier for commercial audio through providing 8-ohm and constant-voltage outputs (70V and 100V). Typical uses are paging, background music, and music-on-hold. However many IP cameras have an audio input and output connections. These connections require special microphones as well as speakers to work correctly. While this amplifier works to merge the two back to your network as shown below. In addition, the 3 Input Amplifier (each with a volume control) provides a 35W amplifier output. While the 4 Input Amplifier (each with a volume control) provides a 60W amplifier output. Lastly, other features include priority muting, voice activated muting, phantom power, as well as bass and treble controls.
Features
- 3 inputs (each with a volume control), and one 35W amplifier output channel
- 4 inputs (each with a volume control), and one 60W amplifier output channel
- Balanced Phoenix-type mic/line input, telephone output, dual RCA stereo music inputs, as well as screw-terminal speaker outputs
- Priority muting by VOX or external switch
- Also includes Bass and Treble controls on master output
- Lastly, Three-Year, No-Fault, Fully Transferable Warranty completely protects your investment as well as guarantees its specifications
