ARRANTY

This warranty is valid only for the original purchaser and only in the United States. We warrant dbx prod-
ucts against defects in material or workmanship for a period of two years from the date of original pur-
chase for use, and agree to repair or, at our option, replace any defective item, except external power
transformers, without charge for either parts or labor. 

IMPORTANT:

This warranty does not cover damage resulting from accident, misuse or abuse, lack of

reasonable care, the affixing of any attachment not provided with the product, loss of parts, or connecting
the product to any but the specified receptacles. This warranty is void unless service or repairs are per-
formed by an authorized service center. No responsibility is assumed for any special, incidental or conse-
quential damages. However, the limitation of any right or remedy shall not be effective where such is pro-
hibited or restricted by law.

Simply take or ship your dbx product prepaid to our service department. Be sure to include your sales slip
as proof of purchase date. (We will not repair transit damage under the no-charge terms of this warranty.)
dbx will pay return shipping.

NOTE:

No other warranty, written or oral is authorized for dbx products.

This warranty gives you specific legal rights, and you may also have other rights which vary from state to
state. Some states do not allow the exclusion of limitations of incidental or consequential damages or lim-
itations on how long an implied warranty lasts, so the above exclusion and limitations may not apply to
you.

OPERATING CONTROLS

Front Panel

HIGH FREQUENCY  or BROADBAND LEDÕs and pushbutton: 

This button controls the pro-

cessing bandwidth and should be switched according to what works better sonically -- which usu-
ally means High Frequency for performance or recording and Broadband for mixing.  See the dis-
cussion About De-Essing, p.10.

GAIN REDUCTION LEDs: 

These 12 LEDs show in decibels how much de-essing is taking place.

GAIN REDUCTION/DE-ESSER slider: 

Moving this slider to the right, in the MORE direction, 

increases the amount of sibilance -- excessive ÒessÓ sounds -- reduction.  Start in the middle,
which is a good choice for the majority of situations.  WeÕll discuss this in detail later.

FREQUENCY:

This knob varies the circuit for specific sibilance frequency ranges.  Start 

around 4 kHz and adjust by ear; discussion later.

Hi-Z MIC INPUT jack:

This connects to the 263AÕs low-noise FET preamp.  Anything plugged into 

this jack overrides the rear input.  ThereÕs enough gain that virtually all high-impedance mics can
be plugged in directly; a trim is on the rear for very hot ones.

Rear Panel

INPUT / OUTPUT Jacks :

These jacks are for a line-level input and output and are the standard 2-

circuit (ÒmonoÓ) 1/4Ó phone type, where the tip carries the signal and the sleeve carries the
ground.

Hi-Z trim:

This control sets the gain of the preamp for the microphone input (see front panel).  The 

gain is set at the factory at +20dB (all the way right, or clockwise) and shouldnÕt be changed
unless your mic output is very hot.  All the way left (ccw) is unity (0dB) gain.
