Do you have a question about the Bouyer AS-4000 Series and is the answer not in the manual?

The Bouyer AS-4156/AS-4256 is a series of mixer amplifiers designed for professional audio applications, available in 150W and 250W versions. These devices feature a robust design with a switching power supply, a 6-input preamplifier stage, and a class-D power amplifier, ensuring efficient and reliable performance.

Function Description:

The primary function of the AS-4156/AS-4256 is to mix and amplify audio signals from up to six different sources, delivering them to a 100V direct output. The preamplifier stage offers extensive flexibility for various input types, including microphones and line-level sources, with options for remote control and automatic signal detection. The class-D power amplifier is equipped with a permanent forced-air cooling system to maintain optimal internal thermal conditions, enhancing reliability and longevity.

Connectivity:
- RJ45 Inputs: Used for remote control consoles (e.g., GX3016, GXT4000) and standard audio signals.
- 3-point Terminal Block Inputs: For balanced audio connections.
- Combo XLR/Jack Inputs: Supports both XLR and 6.35mm jack connectors for microphones and line sources.
- RCA Stereo Inputs: For external music sources, converted to mono.
- 3.5mm Jack Stereo Input: Front-panel input for external devices, converted to mono.
- XLR Output: Balanced 0dBu output.
- RJ45 Output: 0dBu output.
- 100V/70V Output Terminal Block: For connecting loudspeakers.
DIN Connector Microphones: For GM1051, GM1052 microphones on RJ45 inputs 2 and 3, the GZ153 cable (supplied) must be used. It is crucial not to power these consoles locally if connected via RJ45, or to disconnect pin 6 (+17V/100mA) if they are locally powered.
XLR/Jack Combo Connection: Standard wiring for XLR is 2=Hot, 3=Cold, 1=Ground. For 6.35mm stereo jack, T=Hot, R=Cold, S=Ground. For mono 6.35mm jack, T=Hot, S=Ground (output signal attenuated by 6dB for asymmetrical connection).
RCA Connection: Stereo signals from external equipment are converted to mono.

Maintenance Features:

Ventilation: Permanent forced-air cooling system ensures optimal thermal conditions and improved reliability. Ventilation openings must not be obstructed.
Safety Warnings:
- Do not expose the device to water or splashes.
- Connect to a grounded mains socket.
- Do not remove security tags or information.
- Use only for indicated applications.
- Not recommended for use above 2000 meters altitude.
- Maintain a minimum distance around the device for sufficient aeration.
- Do not expose to rain or moisture (unless designed for outdoor use, in which case follow specific instructions).
- If the device malfunctions, or if water/objects enter, immediately power off and unplug. Repairs must be performed by qualified personnel.
- Always power off before touching internal conductive parts.
- Avoid rapidly switching the device on/off multiple times to prevent reducing component longevity.
- Replace fuses only with the same type and caliber.
- Ensure the three-spindle power plug (with ground) is correctly connected to a compatible electrical outlet. Consult an electrician if the outlet is obsolete.
Hot Surfaces: Warning symbols indicate hot surfaces that should not be touched during operation to avoid burns.
Product Disposal: At the end of its life, the product must be disposed of according to the WEEE directive in France (DOM-TOM included). For other regions, local regulations apply. Contact Bouyer for disposal arrangements.
