3. Настройка
Before connecting your MDX1400, ensure all audio equipment is powered off to prevent damage. The unit is designed for standard 19-inch rack mounting.
3.1 Подключение питания
Connect the supplied power cord to the AC inlet on the rear panel of the MDX1400 and then to a suitable power outlet. Ensure the voltagе соответствует требованиям подразделения.
3.2 Аудиоподключения
The MDX1400 features balanced XLR and 1/4" TRS jack connectors for both inputs and outputs. It operates as a two-channel unit, allowing for independent processing of two mono signals or linked stereo operation.
- Входные данные: Connect your audio source (e.g., mixer output, microphone preamplifier) to the INPUT connectors.
- Выходы: Connect the OUTPUT connectors to the next stage in your audio chain (e.g., power amplifier, recording interface).
- Боковая цепь: The sidechain inputs and outputs allow for external control of the compressor/gate. For example, a kick drum signal can be used to "duck" a bass guitar track.

3.3 Operating Level Switch
On the rear panel, locate the operating level switch. Set it to +4 дБн for professional studio equipment or -10 дБВ for consumer-level equipment. Incorrect setting can lead to signal distortion or low signal-to-noise ratio.
4. Инструкция по эксплуатации
The MDX1400 offers intuitive controls for dynamic processing. Each channel has identical controls for independent or stereo-linked operation.
Рисунок 4.0.1: Передняя панель надview of the MDX1400. This image shows the layout of all controls, switches, and LED meters for both channels.
4.1 Expander/Gate Section
The expander/gate section is used to reduce unwanted noise and improve signal clarity by attenuating signals below a set threshold.
- ПОРОГ: Sets the level below which the gate/expander will activate. Turn clockwise to increase the threshold (more aggressive gating).
- РЕЛИЗ: Controls how quickly the gate closes after the signal drops below the threshold. "FAST" for quick cuts, "SLOW" for smoother transitions.
- SC MON (Sidechain Monitor): Activates monitoring of the sidechain signal.
- SC EXT (Sidechain External): Engages the external sidechain input for the gate.

4.2 Compressor/Limiter Section
This section controls the dynamic range of your audio, making loud signals quieter and quiet signals louder, resulting in a more consistent and impactful sound.
- ПОРОГ: Sets the level at which compression begins. Signals above this threshold will be compressed.
- СООТНОШЕНИЕ: Determines the amount of compression applied. A ratio of 4:1 means that for every 4dB increase in input level above the threshold, the output level will only increase by 1dB.
- АТАКА: Controls how quickly the compressor reacts to signals exceeding the threshold. "AUTO" provides automatic adjustment.
- РЕЛИЗ: Controls how quickly the compressor returns to its uncompressed state after the signal drops below the threshold. "AUTO" provides automatic adjustment.
- ВЫХОД: Adjusts the overall output level of the compressed signal.
- INTERACTIVE: Engages the IKA (Interactive Knee Adaptation) feature for a more natural compression characteristic.
- СК ФИЛЬТР: Activates a high-pass filter in the sidechain path to prevent low frequencies from triggering compression.
- ОГРАНИЧИТЕЛЬ: Engages the peak limiter function, preventing the signal from exceeding a set maximum level.
4.3 Enhancer Section
The dynamic enhancer adds clarity and presence to the compressed signal by subtly boosting high and low frequencies.
- ПРОЦЕСС: Activates the enhancer.
- ВЫХОД: Adjusts the amount of enhancement applied.
4.4 Stereo Link Operation
Нажмите СТЕРЕО ССЫЛКА button to link both channels for true stereo operation. In this mode, the controls of channel 1 will affect both channels equally, ensuring consistent dynamic processing for stereo sources.
4.5 LED Meters
The 12-segment LED meters provide visual feedback on input/output levels and gain reduction, allowing for precise monitoring of the dynamic processing.
5. Техническое обслуживание

6. Поиск Неисправностей
If you encounter issues with your MDX1400, consult the following troubleshooting guide:
| Проблема | Возможная причина | Решение |
|---|---|---|
| Нет электричества | Power cord not connected; power outlet faulty; unit fuse blown. | Check power cord connection; try a different outlet; contact service for fuse replacement. |
| Нет аудиовыхода | Incorrect cabling; input/output levels too low; gate threshold too high; compressor gain reduction too high. | Verify all audio connections; adjust input/output levels; lower gate threshold; reduce gain reduction or increase output gain. |
| Искаженный звук | Input signal too hot; output level too high; incorrect operating level setting. | Reduce input signal level; lower output level; ensure operating level switch (+4 dBu / -10 dBV) matches connected equipment. |
| Чрезмерный шум/гул | Ground loop; faulty cables; improper gain stagинж. | Check for ground loops (use a ground lift if necessary, but with caution); replace faulty cables; adjust gain staging throughout your system. |
