The document is an instruction manual for the dbx Model 563X, described as 'THE SILENCER' in the Performer Series. It covers inspection, installation, rack-mounting configurations (single or paired), and safety warnings regarding high voltage and user-serviceable parts.
The guide details the operation of the front panel controls, including the Quieting slider, Hi-Z Gain Trim, and Bypass button, as well as rear panel connections for line-level inputs/outputs and stereo strapping. It includes performance specifications such as frequency response (20 Hz-20 kHz) and THD (0.06%), along with wiring diagrams for mono and balanced setups.
| Filter Design | 2nd-order, minimum-phase design topology |
|---|---|
| Operating Frequency Range | 1.3-38 kHz depending on setting |
| Frequency Response | 20 Hz-20 kHz +1.5 dB on high-level pink noise |
| Total Harmonic Distortion (THD) | 0.06% |
| Input Impedance | 391 k-ohms, single-ended |
The filter operates between 1.3 kHz and 38 kHz depending on the setting.
Connect two units using a 3-circuit (stereo) phone cable, set one unit to Master and the other to Slave via the rear panel button.
No, you must use 3-circuit (stereo) plugs and dual-conductor shielded cable; using mono cables can damage the rms detectors.
