Around the mid to late 80's the 'new-digital' boom was well underway; and the plethora of new budget gear was flooding the market as the home studio boom really took off after the release of the early fostex 8 tracks etc. Quite a few manufacturers responded to the call bringing to the table a whole bunch of cheap plastic-cased tabletop 1/2 size effect units - Companies such as Roland got in there with their BOSS 'mini-rack' series which appeared in two releases... the early grey plastic mini-rack series and the later 'posher' black metal cased series around the early 90's... Accesit were there already with their popular mini series, and others like rebis & Studiomaster had rack slot-in case type racks reminiscent of the famous rack set makes like Neve etc... Then to seal this type of series Alesis brought out their well known 'Micro' series including the famous groundbreaking Microverb 1 & 2... yup.. there certainly was a ton of cheap fx to get your paws on...
Akai entered the fray around 1988 with their 'mini-series of FX units... and this is the EX-75N noise reduction unit which you can pick up for cheap pocket money prices although they are well rare -
The EX-75N has a freq' response from 10Hz to 30Khz and features as far as I can see some sort of ratio based NR with ratio, threshold & decay setting controls on the front panel - so I guess it kinda works like a single band of Dolby NR or something, turning down the signal where the input drops below the threshold based on some sorta proprietry filter chip... The threshold goes down to -50dBv up to -10dbv, plus there's a lowpass filter to remove unwanted low-end rumble & noise etc -
Never used one and have no idea if they are any good or not, but there it is to complete the series we're adding to the FX section - trying to add as many old FX units as you might see in the s/h ad's in your local free-ad's etc... they run of a 12V Dc wall-wart power supply as far as I know...
The Akai EX-75N - anyone used one ?.... user comments please...
