TBP12 is the new professional intercom produced by ELMAN that allows the communication to 4 wires on 12 channels, or to 4 wires on 11 channels plus to 2 wires on 1 channel, on which you can connect more users.

The functions IFB of every channel are separately configurable.
The connection with other apparatuses happens through common connectors XLR.
The TBP12 is an intercom usable in all that cases in which the distance communication is necessary, for example:

TBP12 is compatible with similar apparatuses of other brands in commerce.

On request we can furnish a version of the TBP12 able to feed directly the beltpack terminals 4WBB through the audio cable.

Description

This unit is powered from the telephone line and provides an interface to a 4-wires circuit with separate level control of send and receive signals.
Optimum rejection of the input signal on the 4-wires output is achieved by adjusting SIDETONE NULL trimmer.
This can be used to compensate for local line variations or to adapt to the telephone systems of other countries, where line characteristics may differ.

TBU is compatible with similar apparatuses of other brands in commerce.

4-Wires input

Line input / Headphone amplifier

The BIA (Beltpack IFB Amplifier), battery-powered belt-pack unit, allows either loudspeaker or headphone monitoring of a communication or audio feed, and is typically used with a presenter’s earpiece as part of an IFB kit.

Standard Features

• Selectable limiter: prevents clipping distortion and damage to hearing with earpieces & headphone types
• Built-in 0.5W loudspeaker & amplifier (power to the amplifier is cut when headphones are connected)
• Loop-through male & female XLR connectors enable several units to be driven from a single feed.
• Headphone output on “A” gauge 6.35mm jack.
• Very low battery consumption.
• Low battery voltage indicator.

Description

The input gain is controlled by a potentiometer, a 0/20dB gain switch and a selectable limiter. The limiter can be used to ensure a safe listening level over a wide range of input signal levels and also improves signal intelligibility by preventing clipping of the output signal as the battery discharges.
