31-Band Single-Channel 
1
⁄3 Octave Equalizer
Available in single or two-channel versions, these 
feature packed equalizers offer total control of 31 
frequency bands from 20Hz~20KHz. Each band 
provides 20mm slides, switchable 6dB or 12dB of
boost or cut, for precise tonal control. Constant Q 
circuitry ensures that the bandwidth of the selected
frequency stays the same, even when approaching 
the maximum boost or attenuation. Adjustable 
high and low pass filter allow additional control for
removing noise and rumble. Features: •Adjustable
10Hz~250Hz low cut filter •Adjustable 3KHz~40KHz
high cut filter •Active balanced and unbalanced
inputs and outputs •XLR, 
1

TUBE-MP Microphone
Preamplifier 
Considered the world’s
most popular external
microphone preamp, 
the TUBE-MP utilizes 
a hand picked 12AX7 
preamplifier tube, to add
warmth and fatness to a signal while maintaining
exceptionally low noise and high quality. Designed for
use with a microphone, the TUBE-MP also functions
as an exceptional direct box, impedance matching,
amplifying and improving the sound of any device
plugged into it. Features: •48V Phantom power 
output •Phase reverse •Variable input and output
gain controls •Balanced XLR and 
1
⁄4" inputs and 
outputs •Portable, all steel construction
Specifications: •Frequency response: 10Hz~20KHz
•Dynamic range: >100dB (20Hz ~ 20KHz) •THD:
<0.1% •Dimensions: 2" (H) x 5.5" (W) x 5" (d) 
•Power requirements: 9VAC, AC adaptor included

TUBE MP-OPL™
Microphone
Preamplifier
Includes all of the 
capabilities of the 
world-famous TUBE-MP
(#555-3160), with the 
additional feature of ART’s OPL™ (Output Protection
Limiter), which precisely and accurately controls and
maintains the output peak signal. The OPL circuitry
is crucial in protecting quality of sound in 
environments such as a hard disk recording systems
or a PC sound card. Available with the analog VU 
meter, all features and specifications remain the same
as the original TUBE-MP.
