TAPCO TWEEQ T-231 2X31 BAND GRAPHIC EQ

Built to Tweak.
The Tweeq T?231 is a 2-channel 31-band graphic equalizer that allows you to "tune" your
live sound setup to sound best in any given space. This instrument provides fine control of
31 frequency bands?giving you the power to "shape" your sound with exceptional precision.
Whether you're running live sound or enhancing an installed system, you can count on Tweeq's
bulletproof construction, quality sliders, and great sound quality at a price that just might allow
you to buy two.
Why should you Tweeq?
Your average car or home stereo typically provides bass and treble controls to let you tune your
system to your particular taste. The Tweeq T?231 works in a similar way, but offers much finer
control via 31 separate precision slide controls that boost or cut specific frequencies, ranging from
the lowest bass to the highest treble frequencies. While you can certainly use the T?231 to fine-tune
a PA system to suit your particular tonal preferences, it's most powerful as a tool for correcting issues
like muddy sounding loudspeakers or annoying feedback from stage monitors.
What's to Tweeq?
The T?231 features dual-channel stereo operation with precision sliders for fine control of your audio.
It's designed with constant Q filters for superior sonic performance at 1/3-octave intervals across the
entire range of frequencies normal human beings, drummers and DJs can hear. In addition, both channels
offer variable high and Low Pass Filters for removing unwanted upper and lower frequencies from your
sound, a 6 or 12 dB Range switch for gross- or fine tuning, bright four-segment LED metering, Output
gain control, and a Bypass switch for quick A/B comparisons. And forget the adapters because the
Tweeq T?231 provides RCA, balanced/unbalanced ?-inch and balanced XLR connections for both inputs
and outputs.
Tough, so you don't have to be
Fortunately for you road dogs, the Tweeq T?231 is compact - filling just two spaces in your standard 19-inch
rack-mount road case. It has a switchable 115V/230V power supply in case you're traveling across borders,
and it's designed to be tough enough to withstand the punishing rigors of the road while continuing to perform
set after set, night after night, year after year.

The Rane ME 15S microGraphic Equalizer is a two-channel, 2/3-octave design with 20 mm sliders in a single rack space unit. It features a Range switch for high slider resolution in the ±6 dB mode, equivalent resolution to 45 mm sliders found on the DEQ 60L. The ±12 dB mode provides a wide range of control over system audio.

The active filter sections feature Raneʼs innovative constant-Q (constant bandwidth) design. Constant-Q means the bandwidth of each individual filter is guaranteed to be narrow enough to prevent unwarranted interaction between filters, yet wide enough to produce exactly the type of correction curve demanded by even the most unusual acoustic surroundings. This differs dramatically from conventional designs of the past, encumbered with the unfortunate characteristic of changing bandwidth when changing boost/cut amounts.

Front panel controls and indicators include an overall rotary Level control for each channel as well as Overload indicators. Passive pushbutton Bypass switches feature LED indicators, avoiding ambiguity by being on when the unit is Bypassed. (A passive Bypass switch requires no power to operate. This allows completion of the audio path should power fail in the ME 15S.)

Inputs and Outputs are electronically balanced designs, capable of unbalanced operation when required. They accept and drive all possible signal levels into normal load impedances. Balanced applications choose between the XLR or 1/4" Tip-Ring-Sleeve connectors. Unbalanced sources also may tie to the ME 15S through mono 1/4" connectors (no ring connection).

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.
