If you record music
or voice on a Digital Audio Workstation, you are no doubt aware of the
limitations of many DSP plug-in equalizers - they just don't sound right.
So rather than spend money on expensive software for somewhat better
performance, one could consider the use of an out board analog equalizer
- and that's exactly where the new MPE Parametric EQ from Buzz Audio
fits into your studio!
The MPE-1.1 is a professional quality audio equalizer featuring a High
Pass Filter, High & Low Shelving bands and two Parametric Mid bands.
Individual bypass switches allows the user to remove unused sections
from the signal path and an Input Gain control completes the package.
The
EQ circuitry of the MPE is derived the Buzz
Audio ARC and as standard offers a very smooth sound with little
colouration of the audio signal. For those looking for a bit more colour,
we offer various options for input and output transformers,
which can be fitted at the factory or supplied as a retrofit kit.
The low frequency shelf section of the MPE utilizes a real 16
Henry choke (inductor) as the resonant element resulting in a incredibly
tight and powerful bottom end control - perfect for modern music styles
where bass is all important.
The high frequency shelf section features a switchable tight response
curve which allows the user to boost (or cut) the top end of the audio
band whilst preserving the upper midrange. In broad mode, the high shelf
operates in a more traditional manner. Click

-
High Pass
Filter - continuously variable from 25Hz to 450Hz, musical 12dB/oct
filter slope. Individually selectable in/out.
-
Low Shelf
- choke (inductor) based shelving section with selectable 60Hz and
120Hz turnover points. +/-17dB cut/boost available. Selectable in/out
with High Shelf section.
-
High Shelf
- selectable passive (broad) or active (tight) based shelving section.
+/-17dB cut/boost available. Selectable in/out with Low Shelf.
-
Low Mid
- +/-16dB cut/boost continuously sweepable from 30Hz to 700Hz. Variable
bandwidth (Q) including a tight notch/peak setting. Individually selectable
in/out.
-
Low-High Mid
- +/-16dB cut boost continuously sweepable from 160Hz to 3.4kHz (x1)
or 1.6kHz to 34kHz (x10). Variable bandwidth (Q) including a tight
notch/peak setting. Individually selectable in/out.
-
Input Gain
- providing +/-15dB range.
-
Peak LED
- monitors signal levels at all critical points within the equalizer.
-
All Bypass
- 3 position switch which selects either the DC Coupled input or the
Transformer input (if fitted) or hard bypasses the entire MPE.
-
Two
XLR output connectors (one carries the signal via the output transformer
if fitted).
-
Two
looping XLR input connectors.
