4.1 Fifi sori ti ara

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 Awọn isopọ

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.

• Awọn igbewọle: 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.
• Awọn abajade: 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).
• Agbara: 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. Awọn ilana Iṣiṣẹ

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

• Ipele: Sets the level below which the gate will begin to attenuate the signal. Adjust this to eliminate unwanted noise or bleed.
• Ipin: 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

• Ipele: Sets the level above which compression begins. Signals exceeding this level will be compressed.
• Ipin: 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.
• Ikọlu: 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.
• Tu silẹ: 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.
• Iwajade: Adjusts the overall output level of the processed signal to compensate for gain reduction caused by compression.
• Mita Idinku Ere: A series of LEDs indicating the amount of gain reduction (compression) being applied in dB.

5.3 System idari

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