3. Configuració
3.1 Desembalatge
Traieu amb cura amplifier from its packaging. Inspect the unit for any signs of damage that may have occurred during transit. Retain the original packaging for future shipping or storage.
3.2 Col·locació i muntatge
The RMX5050 is designed for standard 19-inch rack mounting and occupies 3U of rack space. Ensure the rack provides sufficient ventilation and structural support for the amppes del salvador (aproximadament 75 lliures).
3.3 Connexions
Abans de fer cap connexió, assegureu-vos que amplifier is powered off and disconnected from the AC mains.
3.3.1 Connexions d'entrada
The RMX5050 features balanced 1/4" TRS, XLR, and barrier strip inputs for flexible connectivity. Connect your audio source (mixer, preamplifier, etc.) to the appropriate input connectors for Channel 1 and Channel 2.
3.3.2 Connexions de sortida
Connecteu els vostres altaveus al amplifier's outputs using either binding posts or Neutrik Speakon connectors. Ensure correct polarity and impedance matching for optimal performance and to prevent damage to speakers or the ampmés viu.
Figure 3.1: Rear panel of the QSC RMX5050 Power Amplifier. This image highlights the various input options (XLR, TRS, barrier strip), output connectors (Speakon, binding posts), DIP switches for configuration, and the AC power inlet.
3.3.3 Connexió d'alimentació
Connecteu el cable d'alimentació de CA subministrat a amplifier's power inlet and then to a grounded AC outlet. Verify that the power source matches the ampvol de lifiertage requisits.
3.4 Engegada inicial
- Assegureu-vos que totes les connexions d'àudio siguin segures.
- Set the front panel gain controls to their minimum (fully counter-clockwise) position.
- Power on your audio source equipment first.
- Flip the power switch on the RMX5050 to the "ON" position. The power indicator LED should illuminate.
- Slowly increase the gain controls to the desired level.
4. Funcionament del Ampmés viu
4.1 Controls i indicadors del tauler frontal
- Interruptor d'alimentació: Activa o desactiva ampactivador/desactivat.
- LED d'alimentació: S'il·lumina en verd quan el ampel lifier està encès.
- Gain Controls (Channel 1 & 2): Rotary knobs to adjust the input sensitivity for each channel.
- LED de senyal: Illuminates green when an audio signal is present at the input.
- LED de clip: Illuminates red when the output signal is clipping (distorting). Reduce input level or gain if this LED frequently illuminates.
- Protegir el LED: S'il·lumina en vermell si el amplifier enters protection mode due to overheating, short circuit, or other fault conditions.

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.
- Mode de funcionament: Selects between Stereo, Parallel, or Bridged Mono operation.
4.3 Modes de funcionament
4.3.1 Mode estèreo
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 Mode paral·lel
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
El mode mono pont combina el poder de tots dos 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. Manteniment
5.1 Neteja
Netegeu periòdicament l'exterior de la amplifier with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure ventilation grilles are free from dust and debris.
5.2 Ventilació
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.

5.3 Emmagatzematge
Si emmagatzema el amplifier for an extended period, ensure it is kept in a dry, temperature-controlled environment, away from direct sunlight and extreme temperatures. It is recommended to use the original packaging for protection.
6. Solució De Problemes
This section provides solutions to common issues you might encounter. If the problem persists, contact QSC customer support or a qualified service technician.
| Problema | Causa possible | Solució |
|---|---|---|
| Sense poder | Power cord disconnected, AC outlet faulty, internal fuse blown. | Check power cord connection. Test AC outlet. If fuse is suspected, contact service. |
| Sense sortida de so | Input cables disconnected, speaker cables disconnected, gain controls at minimum, amplificador en mode de protecció. | Verify all cable connections. Increase gain. Check Protect LED; if illuminated, refer to manual for fault conditions. |
| Distorted Sound (Clip LED on) | Input signal too high, gain set too high, speaker impedance too low. | Reduce input signal level from source. Decrease amplifier gain. Verify speaker impedance matches ampcapacitats del lificador. |
| Amplifier Overheating (Protect LED on) | Insufficient ventilation, blocked vents, excessive load. | Ensure proper airflow. Clear any obstructions from vents. Reduce load or operating time. Allow amplificador per refredar. |
