The 266XL’s INPUT jacks accept either balanced or unbalanced signals. Input impedance is >40k.. OUTPUT Jacks (CHANNEL 1 and 2): The OUTPUT jacks accept 1/4O balanced or unbalanced phone plugs or female XLR plugs. Maximum output signal level is >+20dBu. In the +4dBu setting, the balanced output impedance is 100., and the unbalanced output impedance is 50.. In the -10dBV setting, the balanced output impedance is 1k. and the unbalanced output impedance is 500.. 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. Note that the switch is slightly recessed. This is to provide protection against accidental activation, possibly causing damage to other system components due to a sudden change in gain. SIDECHAIN INSERT Jack: This jack accepts 1/4O TRS phone plugs and provides a connection to the 266XL detector path. The RING acts as a Send, carrying a buffered version of the signal present at the 266XL INPUT jack, at an impedance of 2k.. The TIP acts as a Return for equipment to feed the 266XL’s detector circuitry, such as an equalizer for de-essing or frequency-sensitive gating/compression. You can also drive the 266XL Sidechain input with the output of most equipment, by using a 1/4O mono phone plug. Input Impedance is greater than 10k.. Note: When a cable is plugged into this jack, it automatically breaks the connection from the INPUT jack to the 266XL's detection circuitry. Rear Panel 266XL Compressor / Gate 266XL Compressor / Gate pressor / Gate IEC - AC Power cord receptacle Plug the AC power cord (supplied) into the 266XL. Plug the other end into a standard wall receptacle. Take care to route power cables away from audio lines. Note that the 266XL does not have a power switch. It is recommended that the 266XL be OOnO at all times. Power consumption is low. If you do not plan to use the 266XL for an extended period of time, unplug it. 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. CONNECTING THE 266XL TO YOUR SYSTEM The 266XL can be used with any line-level device. Some common examples include mixing consoles, electronic musical instruments, patch bays, and signal processors. For all connections, refer to the following steps: Turn Off all equipment before making any connections. Mount the 266XL in a 1U rack space (optional). The 266XL requires one rack space (height) and 1 rack space (width). It can be mounted above or below anything that doesn’t generate excessive heat, since it requires no special ventilation. Ambient temperatures should not exceed 113.F (45.C) when equipment is powered. Make connections via 1/4O phone or XLR jacks according to your requirements. Typical patch points include: a mixer’s channel or subgroup inserts when using the 266XL on individual instruments or tracks; the mixer’s main outputs when mixing; an instrument preamp’s effects loop when using the 266XL for guitar or bass; main outs of a submixer (i.e., keyboard mixer) as the signal is sent to main mixer; between a DAT’s output and an analog cassette input. When using a chain of processors, the 266XL may be placed either before or after effects or dynamics processors. We recommend you use common sense and experiment with different setups to see which one provides the best results for your needs. Connect the AC power cord (shipped with the unit) to the 266XL’s rear panel POWER connector and an appropriate AC power source to turn the unit ON. TECHNICAL SUPPORT AND FACTORY SERVICE The 266XL is an all-solid-state product with components chosen for high performance and excellent reliability. Each 266XL is tested, burned-in and calibrated at the factory and should require no internal adjustment of any type throughout the life of the unit. We recommend that your 266XL be returned to the factory only after referring to the manual and consulting with dbx Customer Service. Our phone number, Fax number and address are listed on the back cover of this manual. When you contact dbx Customer Service, be prepared to accurately describe the problem. Know the serial number of your unit. This is printed on a sticker attached to the side panel of the unit. Note: Please refer to the terms of your Limited Two-Year Standard Warranty, which extends to the first end- user. After the warranty expires, a reasona...
