4. Орнотуу
4.1 Физикалык орнотуу
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 Байланыштар
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.
- Киргизүүлөр: Аудио булагын туташтырыңыз (мисалы, миксердин чыгышы, микрофондун алдын алаamplifier) to the 1/4" TRS or XLR inputs. Both balanced and unbalanced connections are supported.
- Чыгуулары: Connect the processed audio signal from the 1/4" TRS or XLR outputs to your next device in the signal chain (e.g., power ampкөтөргүч, жаздыруу интерфейси).
- 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).
- Күч: 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. Иштөө нускамалары
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
- Босого: Sets the level below which the gate will begin to attenuate the signal. Adjust this to eliminate unwanted noise or bleed.
- Катышы: 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
- Босого: Sets the level above which compression begins. Signals exceeding this level will be compressed.
- Катышы: 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.
- Кол салуу: 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.
- Чыгаруу: 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.
- Чыгуу кирешеси: Adjusts the overall output level of the processed signal to compensate for gain reduction caused by compression.
- Пайданы азайтуу өлчөгүч: A series of LEDs indicating the amount of gain reduction (compression) being applied in dB.
5.3 Системаны башкаруу
- 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.
- Өтүп өтүү баскычы: Bypasses all processing for the respective channel, allowing the input signal to pass directly to the output without any compression or gating.

6. Техникалык тейлөө
Proper maintenance ensures the longevity and optimal performance of your dbx 266xs.
- Тазалоо: Түзмөктүн сыртын тазалоо үчүн жумшак, кургак чүпүрөктү колдонуңуз. Суюк тазалоочу каражаттарды же аэрозолдорду колдонбоңуз, анткени алар капталына же ички компоненттерине зыян келтириши мүмкүн.
- Сактагыч: Узак мөөнөткө колдонулбаганда, аппаратты салкын, кургак жерде, тике күн нурунан жана өтө температурадан алыс сактаңыз.
- Вентиляция: Ашыкча ысып кетүүнүн алдын алуу үчүн желдетүү тешиктери чаңдан жана таштандыдан таза экенин дайыма текшерип туруңуз.
- Кабелдик байланыштар: Periodically inspect all audio and power cables for wear or damage. Replace any faulty cables immediately.
