4. Fametrahana

4.1 Fametrahana ara-batana

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 Fifandraisana

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.

• Fampidirana: 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.
• Output: 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).
• Hery: 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. Torolàlana miasa

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

• tokonam-baravarana: Sets the level below which the gate will begin to attenuate the signal. Adjust this to eliminate unwanted noise or bleed.
• tahan'ny: 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

• tokonam-baravarana: Sets the level above which compression begins. Signals exceeding this level will be compressed.
• tahan'ny: 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.
• Fanafihana: 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.
• Famoahana: 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.
• Fahombiazan'ny vokatra: Adjusts the overall output level of the processed signal to compensate for gain reduction caused by compression.
• Mahazoa metatra fampihenana: A series of LEDs indicating the amount of gain reduction (compression) being applied in dB.

5.3 Fanaraha-maso ny rafitra

• 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.
• Bokotra Bypass: Bypasses all processing for the respective channel, allowing the input signal to pass directly to the output without any compression or gating.

6. Fikojakojana

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

• Fanadiovana: Mampiasà lamba malefaka sy maina mba hanadiovana ny ivelan'ilay fitaovana. Aza mampiasa mpanadio rano na aerosol, fa mety hanimba ny endriny na ny singa anatiny.
• fitahirizana: Rehefa tsy ampiasaina mandritra ny fotoana maharitra, dia tehirizo ao amin'ny toerana mangatsiatsiaka sy maina ilay fitaovana, lavitry ny tara-masoandro mivantana sy ny hafanana tafahoatra.
• rivotra: Hamarino matetika fa tsy misy vovoka sy potipoti-javatra ny varavarankelin'ny rivotra mba hisorohana ny hafanana be loatra.
• Fifandraisana tariby: Periodically inspect all audio and power cables for wear or damage. Replace any faulty cables immediately.
