3. Sąranka

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 Maitinimo jungtis

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 atitinka įrenginio reikalavimus.

3.2 Garso jungtys

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.

Įėjimai: Connect your audio source (e.g., mixer output, microphone preamplifier) to the INPUT connectors.
Išėjimai: Connect the OUTPUT connectors to the next stage in your audio chain (e.g., power amplifier, įrašymo sąsaja).
Šoninės grandinės: 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. Naudojimo instrukcijos

The MDX1400 offers intuitive controls for dynamic processing. Each channel has identical controls for independent or stereo-linked operation.

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.

SLENKSTIS: Sets the level below which the gate/expander will activate. Turn clockwise to increase the threshold (more aggressive gating).
IŠLEIDIMAS: 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.

SLENKSTIS: Sets the level at which compression begins. Signals above this threshold will be compressed.
SANTYKIS: 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.
Ataka: Controls how quickly the compressor reacts to signals exceeding the threshold. "AUTO" provides automatic adjustment.
IŠLEIDIMAS: Controls how quickly the compressor returns to its uncompressed state after the signal drops below the threshold. "AUTO" provides automatic adjustment.
IŠĖJIMAS: Adjusts the overall output level of the compressed signal.
INTERACTIVE: Engages the IKA (Interactive Knee Adaptation) feature for a more natural compression characteristic.
SC FILTRAS: Activates a high-pass filter in the sidechain path to prevent low frequencies from triggering compression.
RIBOTOJAS: 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.

PROCESAS: Activates the enhancer.
IŠĖJIMAS: Adjusts the amount of enhancement applied.

4.4 Stereo Link Operation

Paspauskite STEREO NUORODA 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. Priežiūra

To ensure the longevity and optimal performance of your Behringer MDX1400, follow these maintenance guidelines:

Valymas: Use a soft, dry cloth to clean the exterior of the unit. Avoid abrasive cleaners or solvents, which can damage the finish.

6. Problemų sprendimas

If you encounter issues with your MDX1400, consult the following troubleshooting guide:

Problema	Galima priežastis	Sprendimas
Nėra galios	Neprijungtas maitinimo laidas; sugedęs maitinimo lizdas; perdegė įrenginio saugiklis.	Check power cord connection; try a different outlet; contact service for fuse replacement.
Nėra garso išvesties	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.
Iškreiptas garsas	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.
Per didelis triukšmas / dūzgimas	Ground loop; faulty cables; improper gain staging.	Check for ground loops (use a ground lift if necessary, but with caution); replace faulty cables; adjust gain staging throughout your system.
