ART EQ341 DUAL 15 BAND EQUALIZER

ART?s 341 Dual Channel 15 band 2/3 octave graphic equalizer features: constant Q circuitry
with a 3% center frequency accuracy, 20mm center detent sliders, selectable boost/cut range
of 6dB or 12dB, active balanced and unbalanced input and output connect-ions, variable input
level control, clip level indicators, ground lift switch, internal power supply and selectable line
voltage switch. A range control switch is provided allowing you to set the maximum boost or
cut for each band of equalization to either 6dB or 12dB. Each channel has its own bypass switch
with LED indicator. The rugged, all-steel constructed chassis occupies 1U rack space and is
intended for installation in standard 19" equipment racks.
Multiple input and output configurations are provided for ease of use and incorporate paralleled
connections. The XLR and 1/4" TRS connectors use active balanced, low noise circuitry. XLR
connections are: Pin 1 = ground, Pin 2 = Hot (+), and Pin 3 = Cold (-). The 1/4" TRS connections
are: Tip = Hot (+), Ring =Cold (-), and Sleeve = ground. Both the XLR and 1/4" connectors may
be used in an unbalanced configuration. The RCA jacks are unbalanced. The 341 is designed to
work with a variety of signal levels. The input level control covers a wide range and can easily
accommodate -10 and +4 signal levels. A clip LED will light when a signal level of 5dB before
clipping occurs.
The 341 may be used in a variety of applications such as live sound, recording studios, instrument
racks as well as any conventional fixed installation environment. Use the 341 equalizer wherever
modification of the frequency contour of a sound is needed. The 341 graphic equalizer is a powerful
tool for solving a number of audio problems and creating interesting sound textures. Patch the EQ
between your mixing console and power amps to allow you to alter the overall mix to better match
your environment. Use the 341 between your monitor mixer and monitor power amps to aid in the
removal of feedback inducing frequencies. Patch into a channel insert to EQ one channel or track
individually. Run your instrument directly into the equalizer to enhance its sound before reaching a
power amplifier or instrument amplifier. Patch the 341 into the effects loop of an instrument amplifier
or between a preamp and power amp to have precise control over the complete sound.
The 341 Dual 15 Band Eq has the features and performance you need for any of your audio applications
requiring equalization. For the latest in equalizer technology today, check out the 341 at your favorite

The class-A circuit used in the EQ-73 is similar to the eq section in the classical 1073 module, without the high pass filter. Additional frequencies have been added and the mid frequency band uses two inductors, the higher value of the second one is used for the two lowest frequencies, 160 Hz and 240 Hz, to achieve a suitable response.

The sound character is warm, punchy, sweet and musical. These classic characteristics have been heard on countless recordings through the years and it is a versatile sound that works very well on most sound sources and in most genres. The essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.

The EQ-73 has stepped frequency controls that offers a wide selection of frequencies from 20 Hz to 24 kHz.

The Low and High frequency bands are shelving and the mid frequency band is of the bell type.

The control range is +/-15 dB for the two lower bands and +/- 18dB for the high frequency band.

There are separate bypass switches for all three bands.

The EQ-73 is made to be used together with one of our PRE-73 models that has an Insert jack. It can also be used with many other units that has a low level insert jack.

Combining a PRE-73 and an EQ-73, and using a UNITE rack kit to mount them together, one will get a 19-inch 1073-style unit at a low cost and with a great sound!

1215 Dual 15-Band Graphic Equalizer

The dbx 12 Series were designed to meet the needs of the most
demanding sound reinforcement environments, while offering the
simplicity of straightforward controls. The 1215 provides standard
features like dual channels, 15 2/3 octave bands, ISO frequency
centers, +/-12 dB input gain range, and switchable 40Hz/18 dB per
octave low-cut filters, but also includes other thoughtful features.
These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut
range for precise gain adjustments; XLR, barrier strip, and 1/4'' TRS
connectors for installation ease; balanced inputs and outputs for quiet
operation; and chassis/signal ground lift capabilities for quick hum isolation.
The visionary design of the dbx 12 Series makes your job easier.

The dbx 12 Series Equalizers were precision engineered to provide years
of maintenance-free operation in any application. The magnetically isolated
transformer, electronically balanced/unbalanced inputs and servo balanced/
unbalanced outputs, RF-filtered inputs and outputs, and power-off hard-wire
relay bypass with 2 second power up delay were steps our engineers took
to ensure compatibility for all installations. Only the best components were
utilized, yielding a 10Hz to 50kHz frequency response, greater than 90dB SNR
(ref +4dBu), less than 0.005% THD +Noise (1kHz at +4dBu), and interchannel
crosstalk of less than -80dB from 20Hz to 20kHz. All this attention to detail
is contained in a 2U steel/aluminum chassis.
