CROWN 135MA เพาเวอร์มิกเซอร์ เครื่องขยายเสียง ระบบเครื่องเสียง ประกาศ สาธารณะ Mixer Amplifier Commercial Audio 4 Input 35W 8Ohm & 70V/100V
The Crown® 135MA and 160MA are high value mixer-amplifiers for commercial audio.
They provide 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 35W amplifier output channel in 135MA
- Ideal for paging, background music, and music-on-hold
- Balanced Phoenix-type mic/line input, telephone output, 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
