 Product Description

The Crown 135MA is a high value 35W mixer-amplifier for commercial audio. It provides 8-ohm and constant-voltage outputs (70V and 100V). Typical uses are paging, background music, and music-on-hold. The 135MA provides 3 inputs (each with a volume control) and a 35W amplifier output. Other features include priority muting, voice activated muting, phantom power, and Bass and Treble controls.

Features

  • 3 inputs (each with a volume control), and one 35Wamplifier output channel
  • Ideal for paging, background music, and music-on-hold
  • Balanced Phoenix-type mic/line input, telephoneoutput, dual RCA stereo music inputs, screw-terminal speaker outputs
  • Priority muting by VOX or external switch
  • Bass and Treble controls on master output
  • Three-Year, No-Fault, Fully Transferable Warranty completely protects your investment and guarantees its specifications
