Getting Started

IEC Power Cord Receptacle

The dbx 266xs comes with a power supply that will accept voltages ranging from 100V-120V

at frequencies from 50Hz-60Hz. An IEC cord is included. EU version accepts 220V-240V at

frequencies from 50Hz-60Hz.

WARNING: Be sure to verify your actual line voltage is the same

as the voltage level printed below the AC power receptacle.

Connection to an inappropriate power source may result in

extensive damage which is not covered by the warranty.

Caution: Never remove the cover. There are no user-serviceable parts inside.

INPUT Jacks (CHANNEL 1 and 2)

Use 1/4" TRS phone plugs or male XLR plugs to connect these inputs to your source. The

266xs INPUT jacks accept either balanced or unbalanced signals. Input impedance is >40kΩ.

OUTPUT Jacks (CHANNEL 1 and 2)

The OUTPUT jacks accept 1/4" TRS balanced or unbalanced phone plugs or female XLR plugs.

Maximum output signal level is >+20dBu. In the +4dBu setting, the balanced output

impedance is 100Ω, and the unbalanced output impedance is 50Ω. In the -10dBV setting, the

balanced output impedance is 1kΩ and the unbalanced output impedance is 500Ω.

OPERATING LEVEL Switch

This switch selects between a -10dBV and +4dBu nominal operating level. When the switch is

in the IN position, a -10dBV operating level is selected. When it is in the OUT position, a

+4dBu operating level is selected.

SIDECHAIN INSERT Jack

This jack accepts 1/4" TRS phone plugs and provides a connection to the 266xs detector path.

The RING acts as a Send, carrying a buffered version of the signal present at the 266xs INPUT

jack, at an impedance of 2kΩ. The TIP acts as a Return for equipment to feed the 266xs

detector circuitry, such as an equalizer for de-essing or frequency-sensitive gating/compres-

sion. You can also drive the 266xs Sidechain input with the output of most equipment, by

using a 1/4" mono phone plug. Input Impedance is greater than 10kΩ.

NOTE: When a cable is plugged into this jack, it automatically breaks the connection from

the INPUT jack to the 266xs detection circuitry.
