3. 설정

3.1. 개봉 및 검사

조심스럽게 amp앰프를 포장에서 꺼내십시오. 운송 중 발생했을 수 있는 손상 흔적이 있는지 제품을 검사하십시오. 손상이 발견되면 즉시 판매점에 연락하십시오.

3.2. Rack Mounting and Placement

The RMX2450 is designed for standard 19-inch equipment rack mounting. Secure the amplifier using all four mounting points to ensure stability. Ensure that the rack provides adequate ventilation, allowing for rear-to-front airflow. Avoid placing the amplifier near heat sources or in enclosed spaces without proper air circulation.

• 전원 스위치: 토글 amplifier's main power on or off.
• 전원 LED: 녹색으로 불이 켜집니다. amp리파이어의 전원이 켜져 있습니다.
• 게인 컨트롤(채널 1 및 2): Rotary controls to adjust the input sensitivity for each channel.
• Signal LEDs (Channel 1 & 2): Green LEDs indicate the presence of an audio signal.
• Clip LEDs (Channel 1 & 2): Red LEDs illuminate when the output signal is clipping, indicating potential distortion.

3.4. Rear Panel Connections and Switches

This image shows the rear panel of the QSC RMX2450 amplifier. It highlights the XLR and 1/4-inch input connectors, Speakon and binding post output connectors, a circuit breaker, and various mode switches for configuration, including clip limiting, low-frequency filters, and bridge mono operation.

• Input Connectors (Channel 1 & 2): Balanced XLR and 1/4-inch TRS connectors for audio input. Barrier strip inputs are also available.
• Output Connectors (Channel 1 & 2): Speakon and binding post connectors for connecting loudspeakers.
• 모드 스위치: DIP switches for configuring various amplifier functions:
  • 클립 제한기: Engages or disengages the clip limiting function for each channel.
  • 저주파 필터: Selectable filters (e.g., 30 Hz, 50 Hz) to protect speakers and optimize low-end response.
  • Stereo/Parallel/Bridge Mono: 구성 amplifier's operating mode.
• 회로 차단기: Provides overload protection for the amp리퍼.
• AC 전원 인렛: Standard IEC connector for the detachable power cord.

4. 운영

4.1. 전원 켜기 및 끄기

1. Ensure all connections are secure and gain controls are set to minimum.
2. Flip the front panel power switch to the 'ON' position. The Power LED will illuminate green.
3. To power off, turn down all gain controls, then flip the power switch to 'OFF'.

4.2. 입력 및 출력 연결

오디오 소스(믹서, 프리앰프 등)를 연결하세요.amplifier) to the input connectors (XLR, 1/4-inch, or barrier strip) on the rear panel. Connect your loudspeakers to the output connectors (Speakon or binding posts). Ensure correct polarity for all connections.

4.3. Setting Gain Levels

With the audio source playing at a normal operating level, slowly increase the amplifier's gain controls until the desired volume is achieved. Monitor the Signal and Clip LEDs. The Signal LED should flicker with audio presence, and the Clip LED should only flash momentarily on signal peaks. If the Clip LED stays illuminated, reduce the gain to prevent distortion and potential speaker damage.

4.4. Using Clip Limiters

The RMX2450 features independent defeatable clip limiters. When engaged via the rear panel DIP switches, these limiters reduce peak distortion without sacrificing dynamic range. It is generally recommended to keep clip limiters engaged to protect speakers from excessive clipping.

4.5. Configuring Low-Frequency Filters

The rear panel DIP switches allow selection of low-frequency filters (e.g., 30 Hz, 50 Hz). These filters help protect speakers from damaging sub-sonic frequencies and improve low-end tightness. Select the appropriate filter setting based on your loudspeaker's frequency response capabilities.

4.6. Bridge Mono Mode

For maximum power output into a single load, the RMX2450 can operate in Bridge Mono mode. Refer to the rear panel diagram and DIP switch settings for proper configuration. In this mode, only Channel 1 input is used, and the output is taken from specific binding posts or Speakon pins as indicated on the amplifier. Ensure the connected speaker impedance is suitable for bridge mono operation (typically 8 ohms).
