FAQ
Can I use both output channels independently for different zones?
Yes, each output channel has its own master volume control and tone settings, allowing you to drive zone 1 and zone 2 speakers independently while mixing from the same eight input sources.
What is VOX (voice-activated) ducking?
VOX automatically reduces the volume of input channels 2–4 when microphone input on channel 1 is detected, perfect for paging systems that need to interrupt background music for announcements.
How many microphones can I connect simultaneously?
All eight input channels support microphone-level sources, and phantom power is available for condenser microphones via a rear-panel DIP switch, enabling use of up to eight professional microphones simultaneously.

Frequently Asked Questions
What advantage does an eight-input mixer-amplifier provide for large institutional spaces?
Eight inputs accommodate complex PA requirements—paging, stereo music, emergency alerts, external intercom, backup feeds—in one compact unit, eliminating need for external mixing consoles.
How do two independent stereo outputs enable zone-based audio distribution?
Dual outputs allow separate 120W amplified feeds to different areas (e.g., lobby stereo music and hallway paging), eliminating need for multiple amplifier units.
Is the CSMA 2120 suitable for large corporate campuses or hospital wings?
Yes, the eight inputs and dual 120W outputs are ideal for complex multi-zone institutional PA, supporting simultaneous independent audio routing across large facilities.
Why would a hotel choose a stereo mixer-amplifier over separate components?
The integrated design delivers stereo background music with paging capability in a single 2U unit, reducing equipment complexity and installation costs while maintaining professional audio quality.
How do independent tone controls on each output optimize audio for different zones?
Per-output tone shaping allows different frequency balancing (e.g., warm music for lobby vs. clarity for announcements), without requiring external equalizers or reconfiguration.
Can this mixer-amplifier handle both analog music sources and digital streaming inputs?
Yes, the eight analog inputs can connect to traditional sources; for digital streaming, contact Procure.ae to discuss adapter options or external source equipment integration.
What are the typical lead times for ordering a large eight-input mixer-amplifier?
Lead times depend on order size and current availability; contact Procure.ae to confirm delivery schedule for institutional multi-zone installations.
Does Procure.ae assist with commissioning complex mixer-amplifier systems?
Procure.ae can advise on input routing, zone configuration, and tone shaping for your facility; discuss your multi-zone requirements when requesting setup support.
What is the continuous power output per channel?
The CSMA 2120 delivers 120W per channel (240W total stereo); contact Procure.ae to confirm specifications at different impedance loads.
How many inputs are mic-level vs. line-level, and do they include phantom power?
For details on input sensitivity ranges, phantom power availability, and impedance specs, contact Procure.ae to confirm compatibility with your microphones and music sources.
Does this unit support 70V/100V distributed speaker systems?
For details on transformer support or direct impedance outputs available, contact Procure.ae to confirm compatibility with your speaker configuration.
