- IRC circuit in expander/gate enables "inaudible" elimination of disturbing noise signals.
- Dynamic Enhancer for compression dependent equalization.
- Auto and manual mode compression.
- Separate IRC expander/gate circuits.
- Fully automatic or manually controllable attack and release times.
- Dual-mono or stereo ("true stereo") operation.
- Precise 12-segment LED displays for input/output levels and gain reduction.
- Switchable, external side chain input with side chain monitor function.
- Operating level switchable from +4 dBu to -10 dBV.
- Servo-balanced inputs and outputs.
- XLR and jack connectors.
3. Configuração
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 Conexão de Energia
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 voltage atende aos requisitos da unidade.
3.2 Conexões de Áudio
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.
- Entradas: Connect your audio source (e.g., mixer output, microphone preamplifier) to the INPUT connectors.
- Saídas: Connect the OUTPUT connectors to the next stage in your audio chain (e.g., power amplifier, recording interface).
- Cadeia lateral: 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 dBu for professional studio equipment or -10 dBV for consumer-level equipment. Incorrect setting can lead to signal distortion or low signal-to-noise ratio.
4. Instruções de operação
The MDX1400 offers intuitive controls for dynamic processing. Each channel has identical controls for independent or stereo-linked operation.
Figura 4.0.1: Painel frontal sobreview 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.
- LIMIAR: Sets the level below which the gate/expander will activate. Turn clockwise to increase the threshold (more aggressive gating).
- LANÇAMENTO: 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.
- LIMIAR: Define o nível a partir do qual a compressão começa. Os sinais acima desse limite serão comprimidos.
- RAZÃO: 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.
- ATAQUE: Controls how quickly the compressor reacts to signals exceeding the threshold. "AUTO" provides automatic adjustment.
- LANÇAMENTO: Controls how quickly the compressor returns to its uncompressed state after the signal drops below the threshold. "AUTO" provides automatic adjustment.
- SAÍDA: Adjusts the overall output level of the compressed signal.
- INTERACTIVE: Engages the IKA (Interactive Knee Adaptation) feature for a more natural compression characteristic.
- FILTRO SC: Activates a high-pass filter in the sidechain path to prevent low frequencies from triggering compression.
- LIMITADOR: 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.
- PROCESSO: Activates the enhancer.
- SAÍDA: Adjusts the amount of enhancement applied.
4.4 Stereo Link Operation
Pressione o ESTÉREO LINK 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. Manutenção
To ensure the longevity and optimal performance of your Behringer MDX1400, follow these maintenance guidelines:
- Limpeza: Use um pano macio e seco para limpar a parte externa da unidade. Evite produtos de limpeza abrasivos ou solventes, que podem danificar o acabamento.
- Ventilação: Assegure ventilação adequada ao redor do aparelho para evitar superaquecimento. Não obstrua as aberturas de ventilação.
- Ambiente: Operate the unit in a dry environment, away from direct sunlight, heat sources, and excessive dust or moisture.

6. Solução De Problemas
If you encounter issues with your MDX1400, consult the following troubleshooting guide:
| Problema | Possível causa | Solução |
|---|---|---|
| Sem energia | Power cord not connected; power outlet faulty; unit fuse blown. | Check power cord connection; try a different outlet; contact service for fuse replacement. |
| Sem saída de áudio | 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. |
| Áudio distorcido | 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. |
| Ruído/zumbido excessivo | Ground loop; faulty cables; improper gain stagindo. | Check for ground loops (use a ground lift if necessary, but with caution); replace faulty cables; adjust gain staging throughout your system. |
