Compressor / Gate
Congratulations on choosing the dbx 266XL Compressor/Gate. The 266XL provides
traditional dbx sonic quality and performance for the working musician, DJ, studio
operator or anyone who needs a friendly compressor/gate to achieve quality compression, gating and downward expansion quickly and easily. We recommend that you take
a moment and read through the manual as it provides information that will assist you
in using your unit to its fullest potential.
The 266XL's compressor is packed with just the right features to effectively reduce
and control the dynamic range of your audio, add punch to flabby, loose sounds, or
add sustain to instruments. The 266XL begins with the classic dbx compression made
famous by our 160 line of compressors. Just set the 266XL's Attack and Release controls to 12:00 to get the same response as those units. But there's more. We scaled the
program-dependent Attack and Release controls with dbx's new AutoDynamicª circuitry, so that the 266XL's full range of controls produce voicings that extend from
slow leveling to aggressive peak limiting.
Common Compressor Applications:
¥ Fattening a Kick Drum or Snare Drum
¥ Adding Sustain to Guitar or Synthesizer String Sounds
¥ Smoothing Out a Vocal Performance
¥ Raising a Signal Out of a Mix
¥ Preventing Sound System Overload
¥ Digital to Analog Transfers
The 266XL's gate is ready to tackle all your gating needs, whether you need to remove
unwanted noise or other background sounds, tighten drum sounds, or change the characteristic envelope of an instrument. The 266XL's gate provides more flexibility than
traditional switch gates because it actually functions as a combination gate/expander.
Where switch gates are generally only suitable for a limited number of uses (e.g., gating percussion), the gate on the 266XL acts as a gentle downward expander at low
Ratio settings (suitable for vocals, guitar, mixed program, etc.), and can effectively
work as a switch gate when used at high Ratio settings.
Common Gating Applications:
¥ Gating Dry Percussive Sounds (e.g., Snare Drum, Kick Drum)
¥ Gating Sounds That Have Longer Decay (e.g., Cymbal, Piano)
¥ Gating Hum or Buzz From Live Instruments or Recorded Tracks
¥ Downward Expansion to Reduce Noise Under Smooth Sounds (e.g., Vocals,
Woodwinds)
Refer to the following pages for suggested initial settings. These settings should suffice for traditional compressing and gating requirements. However, the 266XL can
accomplish many more changes to sound quality. We recommend that you experiment
with the 266XL's controls; take our suggested settings and run with them, try totally
different settings, and try unorthodox combinations of compressor and gating controls.
You might be surprised at what you hear. Best of all, you may create the perfect sound
quality for your needs.

OPERATING CONTROLS
Front Panel
3
STEREO COUPLE Switch and LED
This switch sets the 266XL for Stereo or Dual Mono operation. Press the STEREO
COUPLE switch in for stereo operation where Channel 1 becomes the master controller for both channels. All of Channel 2's controls, switches, and LEDs will be disabled (except for Channel 2's GAIN REDUCTION meter), since Channel 2 is the
slave.
With the STEREO COUPLE switch out, the unit functions as two separate mono
compressor/gates, each with its own independent controls.
The red STEREO COUPLE LED indicates that the 266XL is stereo-coupled.
BYPASS Switch and LED
Press this switch in to bypass the front panel controls, effectively canceling the function and processing effect of the 266XL's compression, gating and gain settings. The
input signal is still present at the 266XL's Output, but is now unaltered by the
266XL's controls. BYPASS is especially useful for making comparisons between
processed and unprocessed signals. Note that with stereo operation (STEREO COUPLE switch pressed in), the Channel 1 BYPASS switch controls both channels.
The red BYPASS LED lights when BYPASS is active.
GAIN REDUCTION (dB) Meter
This meter displays the amount of signal attenuated from the input signal by the
266XL's Compressor or Expander/Gate. When the Compressor and Expander/Gate
are both active, the meter displays the maximum amount of gain reduction for
whichever function is greater - Compressor or Expander/Gate.
OUTPUT GAIN (dB) Control:
This control sets the overall gain of the 266XL, from -20dB to +20dB. The OUTPUT
GAIN control is especially useful to compensate for the RMS level decrease which
results from the 266XL's dynamic processing effects. After you adjust the 266XL's
controls for the desired amount of compression, set the OUTPUT GAIN to add the
same amount of gain that is shown on the GAIN REDUCTION meters. For example,
if the average amount of gain reduction shown on the meters is 10dB, then setting the
OUTPUT GAIN control to +10dB will compensate for the 10dB average level reduction at the output.
Note: the 266XL's Compressor and Expander/Gate control settings are interactive and can affect gain, so
watch your playback levels.

Note: Setting the Compressor RATIO to 1:1 will turn the Compressor off, regardless of the setting of the
Compressor THRESHOLD control and BELOW/OVEREASY/ABOVE LED status. Setting the Compressor
THRESHOLD control to +20dB will prevent all but the highest level peaks from being compressed.
OVEREASY¨ Switch
Depress this switch to select the OverEasy¨ compression characteristic. The yellow
THRESHOLD LED turns on when the signal is in the OverEasy region. When the
switch is out, the 266XL operates as a hard-knee compressor, and the yellow LED
does not light.
Compressor THRESHOLD Control and LEDs (BELOW/OVEREASY/ABOVE):
Adjust this control to set the threshold of compression from - 40dB to +20dB. In hardknee mode, the threshold of compression is defined as the point above which the output level no longer changes on a 1:1 basis with changes in the input level.
In OverEasy mode the threshold of compression is defined as the middle of the
OverEasy threshold region, that is, Òhalf-wayÓ into compression.
The three THRESHOLD LEDs indicate the relationship of the input signal level to the
threshold of compression. The green LED lights when the signal is BELOW threshold,
the red LED lights when the signal is above threshold, and the yellow LED lights
when the OVEREASY switch is depressed and the input signal is in the OVEREASY
range.
The 266XL's OverEasy compression permits extremely smooth, natural sounding compression, without artifacts, due to the gradual change of compression around the
threshold. With OverEasy compression, input signals begin to gradually activate the
266XL's internal gain change circuitry as they approach the THRESHOLD reference
level. They do not get fully processed by the RATIO, ATTACK and RELEASE controls until they have passed somewhat above the THRESHOLD reference level. As the
signal level passes the THRESHOLD level, processing increases until it is fully
processed to the extent determined by the control settings.
In hard-knee mode, the 266XL can provide abrupt compression effects as well as hardlimiting applications. Note that when in hard knee mode the yellow LED will not light
as the input signal passes across the threshold. The signal is either being compressed
(over threshold) or it is not being compressed (under threshold).
Note: Even though no input signal is being applied, it is normal for the LEDs to flicker on when the power is
applied or removed.
Compressor RATIO Control:
Adjust this control to set the amount of compression applied to the input signal.
Clockwise rotation of this control increases the compression ratio from 1:1 (no compression) up to °:1 (where the compressor can be considered to be a peak limiter,
especially with faster ATTACK settings).
COMPRESSOR SECTION

266XL
Compressor / Gate
EXPANDER/GATE SECTION

When an input is above the THRESHOLD setting reference level, the RATIO setting
determines the number of decibels by which the input signal must increase in level to
produce a 1dB increase in the signal level at the output of the 266XL. A setting of 2:1
indicates an input/output ratio wherein a 2dB increase in signal (above threshold) will
produce a 1dB increase in output signal. A setting of °:1 indicates that an infinite
increase in input level would be required to raise the output level by 1dB.
Compressor ATTACK and RELEASE Control:
The ATTACK control sets the amount of time it takes the 266XL to begin compressing a signal once the detector has sensed a signal above threshold. The ATTACK
range is from FAST (for a tighter and more noticeable compression effect with very
little overshoot) to SLOW (for more delayed, gradual compression). A very fast
ATTACK setting will cause the 266XL to act like a peak limiter even though RMS
detection circuitry is used. Slower ATTACK settings cause the 266XL to act like an
RMS or averaging detecting compressor/limiter.
The RELEASE control sets how fast the compression circuit returns the input to its
original level. The RELEASE rate is from FAST (where compression follows the
envelope of the program material very tightly) to SLOW (for very smooth compression).
There is no absolute right way to set the ATTACK and RELEASE controls. However,
in general, you will want them set slow enough to avoid pumping or breathing
sounds caused when background sounds are audibly modulated by the dominant signal energy, yet the release must be fast enough to avoid suppression of the desired
signal after a sudden transient or loud note has decayed. For low frequency tones
(e.g., bass guitar), set RELEASE and ATTACK to 2:00 or slower.
Note: ATTACK and RELEASE controls operate together and in conjunction with the RATIO control.
Changing one control may necessitate changing another setting.
Auto Switch:
This switch overrides both the ATTACK and RELEASE controls and enables preset
program-dependent attack and release times. These times are derived from the input
signal and continuously change to match its dynamics. Enabling this AUTO Function
duplicates the Òclassic dbx soundÓ of the 266XLÕs forerunners which have become
standards in the industry.
Note: The Expander/Gate is off when the Expander/Gate THRESHOLD is set to OFF.
Expander/Gate THRESHOLD Control and LEDs (BELOW/ABOVE):
Adjusting this control sets the level at which the gate will open and allow the signal
at the input to pass through to the output. Turning the knob fully counterclockwise (to
OFF) allows the gate to pass all signals unattenuated, effectively bypassing the gate.
Turning the knob fully clockwise causes the gate to attenuate input signals below
+15dBu. The depth of attenuation depends on the setting of the Expander/Gate
RATIO control.
The two Expander/Gate LEDs indicate the relationship of the input signal level to the
threshold setting. The red LED lights when the signal is BELOW threshold, the green
LED lights when the signal is ABOVE threshold.
266XL
Compressor / Gate
Expander/Gate RATIO Control:
This control sets the amount of attenuation applied to the input signal once it is below
the threshold, from gentle downward expansion (appropriate for mixed program,
vocals, etc.), to a hard gating effect (which can be useful for percussion). Fairly low
RATIO (and higher Expander/Gate THRESHOLD) settings work best for downward
expansion, whereas higher RATIO settings (clockwise towards MAX) work best for
gating. If a setting produces undesirable pumping, readjust the Expander/Gate RATIO
or THRESHOLD setting.
Note: The attack and release rate of the Expander/Gate are program-dependent - very fast for transient
material (e.g., percussion) and slower for material with slow attack (e.g., vocals).
Note: Fast gating of sustained low frequency signals can result in “chattering”. To eliminate any “chattering”
simply adjust the RATIO control. The proper THRESHOLD setting will also minimize false triggering and
“chattering.”
INPUT Jacks (CHANNEL 1 and 2):
Use 1/4Ó phone plugs or male XLR plugs to connect these inputs to your source. The
266XL's INPUT jacks accept either balanced or unbalanced signals. Input impedance
is >40k½.
OUTPUT Jacks (CHANNEL 1 and 2):
The OUTPUT jacks accept 1/4Ó balanced or unbalanced phone plugs or female XLR
plugs. Maximum output signal level is >+20dBu. In the +4dBu setting, the balanced
output impedance is 100½, and the unbalanced output impedance is 50½. In the
-10dBV setting, the balanced output impedance is 1k½ and the unbalanced output
impedance is 500½.
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 1/4Ó 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 2k½. 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 1/4Ó mono phone plug. Input
Impedance is greater than 10k½.
Note: When a cable is plugged into this jack, it automatically breaks the connection from the INPUT jack to
the 266XL's detection circuitry.

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 ÒOnÓ 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.
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 113¼F (45¼C)
when equipment is powered.
Make connections via 1/4Ó 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.

Nous vous remercions de votre choix du compresseur/Gate dbx 266XL. Le 266XL
offre la qualitŽ de son et les performances des appareils dbx pour les musiciens, DJ,
opŽrateurs studio et toute personne ˆ la recherche d'un appareil simple permettant une
compression, un Gate ou une expansion de qualitŽ, rapide et facile. Nous vous recommandons de lire ce manuel car il vous permettra d'utiliser au mieux votre appareil.
Le compresseur 266XL poss•de toutes les caractŽristiques pour contr™ler la dynamique
d'un signal, ajouter du punch, diminuer le bruit ou ajouter du "sustain" ˆ certains
instruments. Le 266XL commence avec la classique compression dbx dŽjˆ connue
avec les compresseurs de la sŽrie 160, il suffit de rŽgler les temps d'attaque et de
rel‰chement ˆ mi-course pour obtenir un fonctionnement identique. Mais il peut faire
mieux. Les temps d'attaque et de rel‰chement rŽglables ainsi que le nouveau circuit
dbx AutoDynamic, permettent d'Žlargir la plage de contr™le du 266XL.
Applications courantes de la compression :
¥ Renforcer le son d'une batterie
¥ Ajouter du "sustain" ˆ une guitare ou un synthŽtiseur
¥ AttŽnuer les diffŽrences de niveau des voix
¥ PrŽlever un signal
¥ Eviter une surcharge du syst•me
¥ Optimiser la dynamique lors du transfert numŽrique vers analogique.
Le Gate du 266XL permet d'oter des bruits indŽsirables, de renforcer les sons de batterie ou de modifier l'enveloppe d'un instrument. Le Gate du 266XL est plus polyvalent que les Gates traditionnels car il combine deux fonctions Gate et expanseur. Les
Gates ne conviennent que pour un nombre limitŽ d'utilisations (par exemple percussion), le Gate du 266XL fonctionne comme un expanseur lorsqu'il est rŽglŽ sur des
taux de compression bas (convenant pour les voix, guitares, programmes mixŽs, etc.)
et peut travailler comme un Gate traditionnel lorsqu'il est rŽglŽ sur des taux de compression ŽlevŽs.
Applications courantes du Gate :
¥ Traitement d'un son de percussion sec (par exemple, grosse caisse, batterie)
¥ Traitement d'un son dŽcroissant (par exemple, cymbales, piano)
¥ Traitement des ronflements et bruits d'instruments en sonorisation ou en
enregistrement
¥ Expansion pour rŽduire les bruits rŽsiduels sur des sons doux (par exemple, voix,
bois)
RŽfŽrez-vous aux pages suivantes pour les rŽglages initiaux conseillŽs. Ces rŽglages
conviendront pour une compression traditionnelle et les besoins de Gate courants.
Toutefois, le 266XL peut intervenir de fa•on importante sur la qualitŽ d'un son. Nous
recommandons d'expŽrimenter les contr™les du 266XL ; travaillez avec les rŽglages
proposŽs et essayez en d'autres compl•tement diffŽrents, avec toutes les combinaisons
du compresseur et du Gate. Vous serez surpris par ce que vous entendrez mais en final,
vous pourrez trouver la combinaison parfaite pour vos besoins.
