  • CS3  Conference System

How many microphones can be active simultaneously?

You may choose 1, 3, or 6 open mics; exceeded requests queue until a channel becomes free.

 
 

 

What cable type connects CS3 stations?

The system uses shielded CAT5e cables with modular RJ‑45 connectors for both signal and power.

 
 

 

Do stations need separate power supplies?

Each unit receives 24 V DC over the CAT5 bus from the base unit’s built‑in supply.

 
 

 

Can I adjust individual microphone gain?

Each station has a recessed gain trimmer so softer speakers can be boosted without affecting the mix.

 
 

 

Does the CS3 turn off microphones automatically?

Yes, after 30 seconds of silence the auto‑off timer releases the channel, reclaiming bandwidth.

 
 

 

How long can the CAT5 run be between two CS3 stations?

Individual segments may be up to 30 m, with a total loop length of 120 m before a power inserter is needed.

 
 

 

Is the master line output level adjustable?

The base offers a front‑panel rotary control ranging from ‑∞ to +6 dBu to match any sound system.

 
 

 

Does the CS3 distribute interpretation channels?

The base passes one floor + one interpretation channel, selectable on each headphone dial.

 
 

 

Can the CS3 feed interpreter consoles?

Yes, routing pins on the SUB‑D remote connector provide floor audio to external interpretation mixers.

 
 

 

What headphone impedance works best with CS3 delegate units?

Headphones between 16 Ω and 150 Ω will achieve full volume without distortion.

 
 

 

Are flush‑mount versions available?

Tabletop CS3 DU and CU can be swapped for CS3 F units that recess into furniture without extra wiring.

 
 

 

Does the CS3 include automatic feedback suppression?

While no DSP is on board, the low‑cut on each gooseneck mic and chair control help minimize feedback.

 
 

 

Can I inject background music into the conference?

A balanced XLR line input on the base accepts external audio, which mixes into all headphone outputs.

 
 

 

Is there a hardware mute for fire alarms?

A rear‑panel Phoenix connector accepts a dry contact that instantly mutes all microphones when closed.

 
 

 

What function distinguishes a CS3 chairman unit from a delegate unit?

The chairman station has a priority key that mutes all active delegate microphones and can start or end sessions.

 
 

 

Do I need to create a closed loop like the CS5?

The CS3 uses a simple daisy‑chain backbone; terminate the last station with the supplied terminator plug.

 
 

 

Does pressing the chairman priority key play a chime?

An optional two‑tone chime can be enabled via DIP switch; it sounds briefly before delegates are muted.

 
 

 

How many microphone stations can the CS3 system support?

A single CS3 base unit powers and controls up to 60 microphone stations; larger setups require an additional base.

 
 

 

Is electronic voting available on CS3 stations?

The standard CS3 lacks voting; it focuses on basic discussion, chairman priority, and external audio routing.
