The mainframe contains two internal digital hybrids which provide 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.
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.
(although not infallible) test is to connect to an external modem or fax machine. If the modem or fax operates correctly, the line will probably work with the TS612. To set up analog loop-start extensions for the TS612, contact your PBX system provider.

To prevent electrical shock Line Expansion or possible equipment A six line TS612 is shipped from the factory configured for six telephone damage, disconnect the lines. You may expand a six line system to 12 lines by adding two unit from all electrical power before additional telco cards.
Configuring the TS612 To best suit your requirements, the TS612 may be configured in several ways. The type of configuration is determined by the positions of the DIP switches located behind the access panel on the front of the main- frame.
Page 16
INSTALL ATION • CONFIGURING THE TS612 The TS612 may be used as a single-studio or dual-studio system. In a single-studio setting, the TS612 operates as a dual-hybrid telephone system, with up to 12 lines and three control surfaces: main/studio 1, aux/studio 2, and screener.
In mixed-caller mode, all calls placed to air are routed to the audio console through the Main Caller output regardless of which hybrid a call is routed through. Each of the TS612’s two hybrids has two call slots. This allows up to four calls to be placed to air simultaneously by conferencing them together.
DIP Switch Settings. For split-caller mode, DIP switch 6 should be down. DIP switch 3 determines the mix-minus setup for the configuration. If DIP switch 3 is in the up position, the TS612’s internal 4 5 6 7 8 9 mix-minus feature is active.
This allows the studio console operator to adjust mix from the studio console to the the caller to caller level between the two TS612 hybrids. TS612. 4 5 6 7 8 9...
Main Caller output. All calls placed to air by studio 2 are routed to the audio console through the Aux Caller output. Because each of the TS612’s two hybrids has two call slots, each studio can conference a maximum of two calls together.
Send trim pots. For instructions, see the Calibration section beginning on page 26. As shipped from the factory, the TS612 is set for operation with external (console) mix-minus. If your console does not supply a mix-minus, the TS612 will generate internal mix-minus when DIP switch 3 is placed in the up position.

(and from the telephone line) to an input on the console. When calls are conferenced, the Caller output contains a mix of these callers. The TS612 can conference up to four callers at a time in the conference mode. Both Caller output connections may be required depending on the TS612’s...
50 Vdc 40 mA. It is a DB9 female connector. For pinout mapping, see Appendix B (page 54). As shipped from the factory, the TS612 is set for momentary action of the control signals. If you wish to change the action of the control signals to latching, move DIP switch 2 DIP Switch 2 is a global to the down position.
Aux I/O Hookup The Aux I/O port is a DB25 female connector used to connect auxiliary devices to the TS612. These Aux inputs and outputs provide status information and control using the control surface Aux buttons. The six auxiliary inputs are opto-isolated and require a closure to ground for activation of the input.

Control Surface Hookup You may connect up to three control surfaces to the mainframe. Each Control Surface port on the back of the TS612 mainframe is a DB15 female connector. The port on the back of the control surface is a DB15 male connector.
Page 27
INSTALL ATION • EQUIPMENT INTERCONNECTIONS To prevent accidental disconnection of power to the control surface, install a cable clamp. Secure the U-clamp to the bottom of the control surface. Replace the existing screw with the #4 X 3/8 PPH self-tapping screw (supplied with the U-clamp).
INSTALL ATION • CALIBRATION Calibration Your TS612 has been calibrated at the factory to give optimum audio levels for most studios (+0 dBu). You can make adjustments to audio levels with the front-panel trim pots. The trim pots for send audio, hold audio, caller audio, and automatic gain control of caller audio are behind the front access panel of the mainframe.
INSTALL ATION • CALIBRATION 5. Using the talent control-surface handset in studio 2, repeat steps 1–3 Step 5 through 7 apply to above. Or if you’re using split-hybrid operation, enable conference dual-studio and single-stu- mode and send a second call to air using any control surface. dio split-hybrid operations.
INSTALL ATION • CALIBRATION Calibration of Hold Audio To adjust the hold audio, perform the following steps: 1. Calibrate the send audio for studio 1. 2. Set the program audio at normal operating level. If you have not already connected the program audio to the Hold XLR connector in the Main/Studio 1 section of the mainframe back panel, make that connection now.
INSTALL ATION • CALIBRATION Calibration of AGC AGC (Automatic Gain Control) keeps the caller level from the TS612 to your audio equipment at a relatively consistent level regardless of the level received from the phone line. It’s similar to having someone sitting at the caller trim pot and adjusting the pot up and down for each phone call.

OPERATION • OPERATIONAL SETUP The table below shows the operational modes which can be selected during setup mode. Beginning on page 34, the operational modes are discussed in the order they appear on the table. To select an operational mode, follow the steps below: 1.
4. Return to Operational Mode. Once you have completed setup mode, disconnect power to the TS612 mainframe. Move DIP switch 10 to the up position, then reconnect power to the mainframe. All changes 4 5 6 7 8 9 made during setup are now in effect.

*Master Mode Emulation (All Control Surfaces). This mode allows commands for all control surfaces to be received by the COM port. The TS612 treats commands just as if they were sent from the corresponding control surface. This mode is also valid only when used with RS232 standard mode.
Page 38
OPERATION • OPERATIONAL SETUP Screener Air Control. This mode allows the screener control surface to place callers to air and to remove calls from the air to place them on hold. To place calls to air directly from the handset, press the Air button.
TS612 routes a selected line to the handset. 2. On-Air Telephone. When you leave the handset in the cradle and select a line, the TS612 routes the call to one of the internal dig- ital hybrids for use on-air.
If you are on a call and press another Line button, the first line will be automatically disconnected. However, the TS612 also offers a new fea- ture called Previous Hold Mode. When this mode is enabled in setup (page 32), you can switch lines without disconnecting the previous call.

OPERATION • USING THE CONTROL SURFACE Screener Control Surface Buttons The operation of each of the control surface buttons is dependent upon which mainframe port the control surface is connected to. This section describes the functions of the control surface when it is connected to the screener port.
OPERATION • CALL HANDLING Call Handling On the Handset The following section reviews how calls are handled on the handset. Answering a Call. Pick up the handset and press the line button of the ringing (green flashing) line. You may do this at any time, regardless of whether or not other calls are already on-air.
OPERATION • CALL HANDLING On-Air The following section reviews how calls are handled on the air. Answering a Call On-Air. You must be at a studio control surface to answer a call on the air. (A screener control surface cannot answer calls on-air.) With the handset down, press the line button of the ringing (green rapidly flashing) line.
