4. സജ്ജീകരണം

4.1 ഫിസിക്കൽ ഇൻസ്റ്റലേഷൻ

The dbx 266xs is designed for standard 1U rack space installation. Its dimensions are 1.75" H x 5.75" D x 19.00" W. Ensure adequate ventilation around the unit when mounting in a rack.

4.2 കണക്ഷനുകൾ

The rear panel of the 266xs provides all necessary audio input and output connections. Each of the two channels features independent inputs, outputs, and sidechain inserts.

• ഇൻപുട്ടുകൾ: Connect your audio source (e.g., mixer output, microphone preamplifier) to the 1/4" TRS or XLR inputs. Both balanced and unbalanced connections are supported.
• ഔട്ട്പുട്ടുകൾ: Connect the processed audio signal from the 1/4" TRS or XLR outputs to your next device in the signal chain (e.g., power amplifier, recording interface).
• Sidechain Insert: Use the 1/4" TRS sidechain insert jack to connect external processing devices (e.g., EQ, de-esser) that will control the compressor/gate. This is a Tip-Ring-Sleeve (TRS) jack where Tip is Send (output) and Ring is Return (input).
• ശക്തി: Connect the supplied AC power cord to the IEC power inlet on the rear panel and then to a suitable AC power outlet (100-120V~ 50/60Hz).

5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

The dbx 266xs features intuitive controls for each of its two independent channels. Understanding these controls is key to achieving desired audio dynamics.

5.1 Expander/Gate Controls

• പരിധി: Sets the level below which the gate will begin to attenuate the signal. Adjust this to eliminate unwanted noise or bleed.
• അനുപാതം: Determines the amount of attenuation applied once the signal falls below the threshold. Higher ratios result in more aggressive gating.
• Gate LED: Indicates when the gate is active.

5.2 Compressor Controls

• പരിധി: Sets the level above which compression begins. Signals exceeding this level will be compressed.
• അനുപാതം: Controls the amount of compression applied. A ratio of 2:1 means that for every 2dB the input signal goes over the threshold, the output will only increase by 1dB.
• Overeasy® Button: Engages dbx's patented Overeasy compression, providing a smoother, more natural compression curve. When disengaged, the compression is hard-knee.
• ആക്രമണം: Determines how quickly the compressor reacts to signals exceeding the threshold. "Fast" settings react almost instantly, while "Slow" settings allow initial transients to pass through.
• റിലീസ്: Controls how quickly the compressor returns to its normal state after the signal falls below the threshold. "Fast" settings result in quick release, while "Slow" settings provide a more sustained effect. The 266xs features AutoDynamic™ attack and release for simplified operation.
• ഔട്ട്പുട്ട് നേട്ടം: Adjusts the overall output level of the processed signal to compensate for gain reduction caused by compression.
• ഗെയിൻ റിഡക്ഷൻ മീറ്റർ: A series of LEDs indicating the amount of gain reduction (compression) being applied in dB.

5.3 സിസ്റ്റം നിയന്ത്രണങ്ങൾ

• Stereo Couple Button: Links Channel One and Channel Two for stereo operation. When engaged, Channel One's controls act as the master for both channels.
• ബൈപാസ് ബട്ടൺ: Bypasses all processing for the respective channel, allowing the input signal to pass directly to the output without any compression or gating.

6. പരിപാലനം

Proper maintenance ensures the longevity and optimal performance of your dbx 266xs.

• വൃത്തിയാക്കൽ: Use a soft, dry cloth to clean the exterior of the unit. Do not use liquid cleaners or aerosols, as they may damage the finish or internal components.
• സംഭരണം: ദീർഘനേരം ഉപയോഗിക്കാത്തപ്പോൾ, യൂണിറ്റ് തണുത്തതും വരണ്ടതുമായ സ്ഥലത്ത് സൂക്ഷിക്കുക, നേരിട്ടുള്ള സൂര്യപ്രകാശത്തിൽ നിന്നും കടുത്ത താപനിലയിൽ നിന്നും അകറ്റി നിർത്തുക.
• വെൻ്റിലേഷൻ: അമിതമായി ചൂടാകുന്നത് തടയാൻ വെന്റിലേഷൻ ഓപ്പണിംഗുകൾ പൊടിയും അവശിഷ്ടങ്ങളും ഇല്ലാത്തതാണെന്ന് പതിവായി പരിശോധിക്കുക.
• കേബിൾ കണക്ഷനുകൾ: Periodically inspect all audio and power cables for wear or damage. Replace any faulty cables immediately.
