4.1 Алдыңкы панелдин башкаруу элементтери жана көрсөткүчтөрү
- Кубат которгучу: Күйгүзөт ampкөтөргүч күйгүзүү/өчүрүү.
- Power LED: болгондо жашыл күйөт ampкөтөргүч күйгүзүлгөн.
- Күчөтүүнү башкаруу элементтери (1 жана 2-канал): Rotary knobs to adjust the input sensitivity for each channel.
- Сигнал LED: Illuminates green when an audio signal is present at the input.
- Клип LED: Illuminates red when the output signal is clipping (distorting). Reduce input level or gain if this LED frequently illuminates.
- Protect LED: Illuminates red if the amplifier enters protection mode due to overheating, short circuit, or other fault conditions.
Figure 4.1: Front panel of the QSC RMX5050 Power Amplifier with the power indicator illuminated. This view clearly shows the power switch, gain knobs, and the Signal, Clip, and Protect LEDs for both channels.
4.2 Rear Panel DIP Switches
The rear panel features DIP switches that allow configuration of various operating parameters. Always power off the amplifier before changing DIP switch settings.
- Clip Limiter: Engages a circuit that prevents severe clipping and protects speakers.
- Low-Frequency Filters: High-pass filters (e.g., 30 Hz, 50 Hz) to remove unwanted low-frequency content, protecting speakers and improving clarity.
- Иштөө режими: Selects between Stereo, Parallel, or Bridged Mono operation.
4.3 Иштөө режимдери
4.3.1 Стерео режим
In stereo mode, each channel operates independently, amplifying its respective input signal and sending it to its dedicated output. This is the standard mode for two-channel sound reinforcement.
4.3.2 Параллель режим
In parallel mode, a single input signal is fed to both amplifier channels, which then drive separate speaker loads. This is useful for driving multiple speakers with the same mono signal.
4.3.3 Bridged Mono Mode
Bridged mono режими экөөнүн тең күчүн айкалыштырат amplifier channels into a single, higher-power output. This mode is typically used to drive a single, high-power loudspeaker or subwoofer. Consult the manual for specific wiring instructions for bridged mono operation.
5. Техникалык тейлөө
5.1 Тазалоо
Сырткы бетин мезгил-мезгили менен тазалап туруңуз amplifier with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure ventilation grilles are free from dust and debris.
5.2 Вентиляция
The RMX5050 relies on internal fans for cooling. Regularly check that the air intake and exhaust vents are not obstructed. Operating the amplifier in poorly ventilated spaces can lead to overheating and activation of protection circuits.
