The Banlie Mixed Amplifier is a high performance multi-functional device with four mono microphone inputs and one music input. It can meet a variety of public broadcasting requirements, and the cost is very low.

basic function

All input channels are equipped with phantom power supply, which can supply power for capacitive microphones and optional voice filters, thus improving clarity. In addition, input channels 3 and 4 can be switched according to line sensitivity. Independent music input has its own input selector and volume control.

The priority of input channel 1 can be higher than all other microphones and music input.

This priority function will be activated when the contacts on the 5-pin DIN interface are closed or the signal level on channel 1 exceeds the predetermined value (VOX). The user can configure the amplifier to play two tone prompts before playing the preferred broadcast. Phone or emergency input with VOX activation and its preset volume control will take precedence over all other inputs.

Loop input and output connections allow external sound processing devices, such as equalizers and piercing feedback suppressors, to be connected between preamplifiers and power amplifier components. The LED VU table is used to monitor the main output. The device is also equipped with a tape output channel.

Various models with different maximum output power are provided for the Banlie hybrid amplifier.

The 70 V and 100 V constant voltage connection lines and 8 ohm low impedance connection lines can directly provide such power. In addition, these amplifiers have independent 70 V/100 V "call-only" output channels for broadcast areas requiring only priority broadcasting, while 70 V/100 V "mixed-only" output channels are used for areas requiring no priority broadcasting. The "Call Only" output can also be used for 3-wire remote volume control. If the required power is greater than the output power provided by the built-in power amplifier module, additional spotted power amplifiers are allowed in a loop layout.

The main device is connected to the output of the equalization line.

The function of LBB 1914/10 is the same as that of LBB 1912/10, but it also has two front panel switches for guiding the amplifier output to two separate areas. This is very useful when certain areas of a building do not need to hear certain radio or background music. However, priority calls are always sent to these two areas.
