SPECIFICATIONS

A microphone hub for connecting up to four 
Sennheiser SpeechLine microphones and 
bundling the microphone cables into one, 
thus significantly reducing the amount of 
cables required in a TeamConnect conferenc-
ing system.

Audio signals from the SpeechLine micro-
phones shall be distributed from the hub to 
the TeamConnect central unit via a single 
Cat5 cable while logic signals shall be sent 
directly from the hub to the TeamConnect 
combox using a 6-wire cable with a 6-pin 
terminal connector on each end.

The hub shall be “plug and play” without the 
need for an external power supply. The hub 
shall feature four microphone inputs (5-pin 
terminal) and an audio output (RJ-45) for 
connecting to the TeamConnect central unit. 
The pin allocation of the microphone inputs 
shall be as follows: pin 1: microphone mute 
control, pin 2: microphone mute status, pin 3: 
ground, pin 4: audio +, pin 5: audio –.

The hub shall be equipped with two GPIO 
ports (6-pin terminal): one for connecting to 
the TeamConnect combox and one for either 
daisy-chaining a second hub or for connect-
ing an external hook button.  
 

The 

SL Mic Hub 1

 simplifies the cabling for integrated audio conference sys-

tems. It reduces the amount of cables that have to be integrated by a significant 
amount by bundling up the audio signals into a single Cat 5 cable.

POWER SUPPLY
The SL Mic Hub 1 ist connected to the TeamConnect Combox CB1 via a 6-pin 
terminal connector cable. The Combox delivers the necessary power supply to 
operate the bi-color status LEDs of the mute button MAS 1 TC and the hook but-
ton MAS 2 TC. The Combox supplies sufficient power for up to 5 MAS 1/2 buttons. 
If you want to use more than 5 buttons in your setup, you need to connect an 
external power supply (5 V, >100 mA, recommended Sennheiser Power supply 
Art.-No. 534480) to pin 6 and 7 of the MUTE socket.
