HOW IT WORKS...

The Norcon TTU® system permits hands-free, 2-way communication between the booth attendant and the customer. Unique circuitry facilitates ongoing, clear, 2-way conversation at all times – as if the two parties were together in the same room. The TTU®-1X Talk-Thru Communicator now incorporates circuitry to automatically attenuate the outside channel. If the gooseneck microphone is not used for a period of 30 seconds, the outside channel volume will be reduced approximately 70%. Normal operation is restored as soon as the attendant speaks into the gooseneck microphone. The automatic volume attenuation circuit prevents outside noise from bothering the attendant.
The TTU® -1X provides clear communication even in environments with high ambient noise by shaping the sound for maximum intelligibility. Its compression circuitry decreases loud, annoying sounds.

HOW TO INSTALL...

Installation of the TTU® -1X is a very simple, one-person operation. All that's needed is a 3" to 4" diameter cutout in the barrier. Four fasteners and two rubber gaskets for mounting are supplied. The front face and housing are easily mounted on opposite sides of the barrier using the fasteners. The rubber gaskets prevent slippage and protects the barrier surface. The electronic section is then inserted into the housing and fastened in place.

Installation Instructions:
Remove the four (4) 6-32 assembly screws.
Separate the housing and electronics assembly. Unplug electronic assembly from the faceplate and housing.
Set the electronic assembly aside, carefully.
Remove the four (4) 8-32 mounting nuts from the mounting rods. Separate the faceplate and housing. Discard the shipping spacers located between the faceplate and housing if there are any. Hold the faceplate over the partition opening. Carefully center the faceplate and align the lettering horizontally. Masking tape can be used to temporarily hold the faceplate to the outside of the partition.

On the inside of the partition mount the housing over the four (4) 8-32 mounting rods. Be certain to position the housing so that the threaded hole is positioned properly. If using tubing, orient the hole in the direction which the tubing is to exit (left, right, top, and bottom). If tubing is not being used, place the plugged hole at the bottom.

Recommended cables for wiring:
For power connections use West Penn wire #221. This is a stranded single pair 22 awg, Plenecon -II jacket Rohs cable. Keep Mic/spk and power cable bundles away from other power cable.
For power connection, route the one pair cable (with the connector on one end). From the inside unit to the location of the PS-1 power supply. Connect the conductors to the power supply (RED to +ve, BLACK to -ve). Plug the connector to its mate from the printed circuit board. Connect 4 – pin polarized connectors and reassemble units

Place the housing so that the threaded hole can be positioned properly. If using tubing, orient the hole in the direction in which the tubing is to exit as shown in the drawing.

Be certain to position the housing so that the threaded hole can be positioned properly. If using tubing, orient the hole in the direction which tubing is to exit.

HOW TO USE THE TALK-THRU COMMUNICATOR...

1. With power switch off, turn Talk and Listen controls completely counter clockwise.
2. Turn on the unit by switching the Power ON/OFF switch to its upper position. At this position, the unit is at the auto mute mode.
3. Adjust the TALK volume control until the attendant is clearly heard by the person outside the window when the attendant is speaking 2" to 4" from the gooseneck microphone at a normal speaking level. The t green LED should go on when the attendant starts talking and go off when the attendant stops talking. If the green LED stays lit constantly, it indicates either the TALK volume setting or the ambient noise is too high.
4. Adjust the LISTEN control until the person outside the window is clearly heard when speaking at a normal level.

OPERATION HINTS

1. Increasing the talk volume control allows the attendant to speak further away from the microphone as well as increasing the talk channel volume. The optimum distance from the microphone should be maintained at approximately 2"-4" or conversations not directed to customers may be heard outside the booth. Watch the green LED above the TALK volume control, it should be ON only when talking into the gooseneck microphone and off when not talking to the microphone.
2. Installing a headset into the Headset jack will allow communications from the headset and disconnect the speaker and the gooseneck microphone.
3. The unit will decrease the incoming volume level by approximately 70% some 30 seconds after the attendant stops speaking into the microphone. The purpose of this feature is to decrease the amount of extraneous noise entering the booth. Normal volume level is restored when the attendant speaks into the microphone. The muting function can be defeated by switching the POWER SWITCH to the NO MUTE position.

Introducing the Norcon TTU® -3X Series

There are times, when it is inconvenient to cut a 3" to 4" hole through an isolation barrier; the Norcon TTU®-3X is the solution for this situation.

The TTU®-3X is a pair of 6" or 12" prism-shaped units for mounting on a counter top on both sides of a barrier. They allow hands free n communication through barriers typically found in banks, cashier's booths, information booths, and similar environments. _ne Norcon provides audio/visual, communications, and secure talkthru solutions for critical applications around the world. TTU-3X with removable mic for your convenience.

Introducing the Norcon TTU®-7X

Special design for the window with a secure pull-down gate or shade.

In some cases, when it's impractical to mount the inside control section of the TTU®-3X in a window with secure gate or shade the TTU®-7X is your choice. The TTU®-7X incorporates the same highquality electronics as the basic TTU®-3X, but with a 1" low profile window mount section, and a prism shaped counter mounting control section.

Introducing the Norcon TTU® -1 NCX:
When using a Talk-thru unit in a noisy area such as heavy traffic street, a crowed movie theater hall way or a gas station, the noise makes the conversation difficult. A powerful DSP inside the Norcon noise cancelation unit samples an ambient noise environment and attenuate the noise around the desired speech signals. As a result, continuous and repetitive noise is removed; a clear conversation will be even with a passing truck in the background.
To take the advantage of this new technology, the existing unit can be sent to us for upgrade.
