Recent developments in sound measurement techniques have revealed the limitations of existing graphic equalisers. The wealth of data that such equipment can provide for the users requirements - feedback suppression, increased headroom, room equalisation/ compensation can no longer be adequately provided for with a simple graphic equaliser. The Apex PE MKII is the solution, providing a tool which both enables maximum correction whilst shaping the response to your specific requirements, combining a full graphic equaliser with a complementary parametric equaliser/notch filter.
FEATURES: Electronically balanced input with a balanced floating output stage. All potential overload points are continuously monitored by an extremely fast "peak-peak" overload detecter circuit, followed by a "peak-stretching" circuit for clear indication of overload conditions. Reliablilty is the hallmark of any product, and the mechanical integrity of the components housing is the vital prerequisite. Sophistical CAD programmes and advanced engineering concepts have been applied to the chassis design to eliminate the stress and torsional movements which can damage the electronics.Special attention has been given to the purity of the signal path.The musicality of previous designs of Apex equalisers has been well appreciated by users, and the PE continues this tradition, noise and distortion are significantly better than 16-bit digital. Fine-tuning your system is essential. The "vernier control" provides adjustment refinement on an unprecedented scale. In the event of power failure to the unit, a failsafe relay links the input to the output ensuring that signal continuity is maintained.

DBX 2215 Dual 15-Band Graphic Equalizer with Noise Reduction
It's amazing. One little button. So much effect. dbx? Type III? Noise Reduction is an entirely new concept... virtually instantaneous encode/decode within the circuitry of the box. We started out to build the finest EQs possible, boxes with the heritage and performance to rival our famous 30 Series EQs. And to no one's surprise they came out awfully darn good. (Ask to see the Audio Precision plots compared to the competition.) But then, Roger (our chief engineer, a nice guy, as far as engineers go) got the crazy idea of putting this new noise reduction stuff in the box. We listened to it and were amazed. The EQs sounded great without it but with it the performance was nothing short of incredible. Check it out yourself and see.
But hey, Roger wasn't about to stop there. PeakPlus? Limiter. Who knows more about limiting than the folks at dbx; nobody... that's who. So when the guys were developing this new series of EQs they wanted something that would be unique to these EQs. That's when Roger got another one of his bright ideas and said "I bet they'll work a lot better if there's a cool limiter built in." Next thing you know, all the guys are in the studio amazed at the new limiter Roger had designed specially for the 20 Series. Once again, hearing is believing... With a threshold range of 0dbu to plus 20dbu, the patent-pending PeakPlus limiter is designed to tame your program material from the subtlest nuances to the rowdiest hits. Also, the four stage LED ladder gives you a great visual indication as to what the limiter is doing.
20 Series EQs. You used to have to settle for second best in a reasonably priced EQ but not any more. With the new 20 Series from dbx Professional Products you get a great EQ circuit, a graceful yet powerful limiter and the revolutionary new design of the Type III Noise Reduction. Check out the dbx 20 Series graphic EQs at your pro audio outfitter. You'll see, with the 20 Series EQs you get MORE!!!

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).
Features - Constant-Q Bandwidth Design
- Overall Level Controls and Passive Bypass Switches
- 20 mm Filter Slide Controls with ±6 dB or ±12 dB Slider Range
- Infrasonic, Ultrasonic, & RFI Filters
- Balanced XLR and 1/4" TRS Inputs and Outputs
- Universal internal switching power supply (100-240 VAC)
