THE JOEMEEK MQ3

WHAT IT IS

The JOEMEEK MicroMeek MQ3 is an input conditioner. A microphone or 
musical instrument preamplifier designed to bridge the gap between the 
performing musician and the recording studio.

It has been designed specially to be easy to operate, yet will give the finest 
professional 'glitter' to the sound; but without hours of tweaking knobs and 
switches with unrecognisable names!

QUALITY AND BIG SOUNDS

It's my theory that 'big' sounds can only be produced if the lower 
frequencies in an input amplifier are kept absolutely flat and under control. 
To achieve this, the JOEMEEK MICROMEEK has an extended frequency 
range down well below 20Hz. This ensures that there are no sudden phase 
shifts in the low end. The proof of the theory is that it sounds great!

OVERLOAD MARGINS

In the mid 1970s I designed a range of mixers specifically for Independent 
Local radio stations and the BBC.  One of the specification clauses insisted 
on by them was an extreme overload margin on the microphone amplifier.
The reason was that although momentary overloads (transients) are not 
audible, they have an effect on the quality of the sound you hear. A high 
overload margin amplifier just sounds better.  Nowadays, many of these 
notions have been forgotten and 'quality' electronics is getting rarer and 
rarer. But the  JOEMEEK range of Studio channels and the MQ3 apply 
these professional rules and you can hear the difference!
The function of a microphone preamplifier is not too difficult and the 
microphone/input amplifiers on normal professional mixers do it quite well; 
BUT they cut costs and corners. The JOEMEEK MQ3 has a specialist 
approach, it uses a super quality transformerless input stage in combination
