Gentner TS612 Control Surface, sn2487-0305-6954.

Gentner TS612 Control surface, for 6 or 12 line Mainframe, Excellent condition. Currently SOLD OUT.
Beschikbaarheid:: Niet op voorraad

These control surfaces require a Gentner/ClearOne TS612 Mainframe, and have been tested with Extron 12Volt power supplies which are included with the Control Surface.   Please Note; these are not the original Gentner power supplies. 

This Control surface is a 2004 model and can be used as the Main Studio Control or at the Screener position.  It connects to the TS612 using a standard 15 pin DB M-F cable (Not Included).    Cosmetic condition is Excellent and there is no noticeable wear to the keypad, or any of the controls.   All of the LEDs and controls work.   This unit is close to new in appearance.


Here are some specs from Gentner/Clearone.   Please note this information is from the Current edition (2016) and includes features of the Mainframe itself.    In addition, all of the software/firmware references may not apply:

Control Surface Buttons
The operation of each of the control surface buttons is dependent upon which mainframe port the control surface is connected to. The buttons will be discussed first as they function when the control surface is plugged into a studio port. A discussion of button use with the screener port begins on page 43 of the manual.

Telephone Line Buttons. The Line buttons are used for selecting telephone lines. Pushing a Line button will select that line. If the handset has been picked up before the line is selected, the call will be connected to the handset. If the handset is down when a Line button is pressed, the call will be placed on the air.

LED Color Coding. Each Line button has an LED line-status indicator located above it. These LED’s have three colors to indicate call
status: red, green, and amber. The status indications for Line LED are described below.
Not in use. When a line is not in use, the LED is off.
Ringing. A ringing line is indicated by a green LED that flashes on at a quick 4 Hz rate for one second, then off for one second, in a
repeating cycle until answered.
In use on handset. When a call is connected to the handset, the Line LED will appear solid green.
In use on-air. A line that is in use on-air is indicated by an LED that is solid red.
In use elsewhere. When a call is in use by another control surface, or a networked TS612 mainframe, or downstream equipment, the
Line LED will appear solid amber.
On hold. A line on hold is indicated by a green LED that is flashing at a slow 1 Hz rate.
On screened hold. A line on screened hold is indicated by a red LED that is flashing at a quick 2 Hz rate.


The TS612 features two internal digital hybrids, providing high-quality interface to six telephone lines (expandable to 12). The dual hybrids allow the TS612 to operate as a single-studio telephone system able to conference up to four callers simultaneously, or a two-studio system able to conference two callers to each studio.

Dual-Studio In this configuration, the TS612 operates as two single-hybrid telephone systems in either split or shared mode.

Split Mode. In split mode, the two talent control surfaces operate independently. Studio 1 controls lines 1–6 and studio 2 controls lines
7–12. The screener accesses all 12 lines to screen calls for either talent.

Split-Caller Mode You can use the TS612 as a single studio system and bring each of the hybrid outputs independently to the audio console with a single feed for both hybrids.
Split-Hybrid Mode Like Split-Caller Mode, you can bring each hybrid out to the console independently. However, you can return independent feeds for each hybrid in Split-Hybrid Mode.
This mode places calls on hold automatically when you select another line. You can switch between previous-hold mode and traditional line switching (with automatic disconnect) via the control surface.
Two-Button Hold
With Two-Button Hold you can place a single call on hold when two or more lines are conferenced together.
Two-Button Off
This mode allows you to disconnect any line by pressing the Off button followed by the line button you wish to disconnect.
Screener Air Control
When enabled, this mode allows the screening control surface to place calls to and from air.
