3. سیٹ اپ
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 پاور کنکشن
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 یونٹ کی ضروریات سے میل کھاتا ہے۔
3.2 آڈیو کنکشن
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.
- ان پٹ: Connect your audio source (e.g., mixer output, microphone preamplifier) to the INPUT connectors.
- آؤٹ پٹ: Connect the OUTPUT connectors to the next stage in your audio chain (e.g., power ampلائفائر، ریکارڈنگ انٹرفیس)۔
- ایک طرف کی زنجیر: 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 ڈی بی یو for professional studio equipment or -10 ڈی بی وی for consumer-level equipment. Incorrect setting can lead to signal distortion or low signal-to-noise ratio.
4. آپریٹنگ ہدایات
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.
- تھریشولڈ: Sets the level below which the gate/expander will activate. Turn clockwise to increase the threshold (more aggressive gating).
- رہائی: 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.
- تھریشولڈ: Sets the level at which compression begins. Signals above this threshold will be compressed.
- تناسب: 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.
- حملہ: Controls how quickly the compressor reacts to signals exceeding the threshold. "AUTO" provides automatic adjustment.
- رہائی: Controls how quickly the compressor returns to its uncompressed state after the signal drops below the threshold. "AUTO" provides automatic adjustment.
- آؤٹ پٹ: Adjusts the overall output level of the compressed signal.
- INTERACTIVE: Engages the IKA (Interactive Knee Adaptation) feature for a more natural compression characteristic.
- ایس سی فلٹر: Activates a high-pass filter in the sidechain path to prevent low frequencies from triggering compression.
- حد: 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.
- عمل: Activates the enhancer.
- آؤٹ پٹ: Adjusts the amount of enhancement applied.
4.4 Stereo Link Operation
دبائیں اسٹیریو لنک 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.
