Control

 

Introduction

The 

2

Control  combines  loudspeaker  and  headphone  monitoring  in 

a  compact,  user-friendly  and  high  quality  control  device.  Any  studio 
based on a digital audio workstation (DAW) can benefit from its impor-
tant and essential monitoring functions. The concept of the 2Control is 
based on a dual-channel operation that allows for connection of two 
sources, two stereo speaker sets and two headphones.

The advantages of an analog monitoring controller becomes especially 
apparent in combination with modern audio and video production tools 
such as ProTools™, Nuendo™, Cubase™, Logic™, Deck™, etc. Monitor 
levels  and  source  management  can  be  handled  independently  of  the 
software and with virtually no loss in quality. You no longer need to set 
up additional aux sends for monitoring. In addition, you won’t have to 
worry about over- or underdriving the converters when changing moni-
tor levels. 

The  high-quality  2Control  speaker  volume  potentiometer  and  active 
circuits correspond with the high demands in professional audio ap-
plications regarding sound quality and usability. In contrast to passive 
circuits,  the  2Control’s  active  designs  do  not  influence  impedances 
when levels change. Altering impedances would again have effects on 
the  frequency  response,  so  the  2Control’s  active  design  guarantees 
linearity. Often there is the need to “zoom” into audio material when 
listening to quiet passages or checking for artifacts etc. – and only ac-
tive designs offer signal amplification.

Each of the three speaker outputs (2 x stereo, 1 x mono) is driven by 
its own balancing stage to exclude signal degrading mutual influences. 
Each headphone output is supplied by a separate amplifier to allow for 
completely independent operation of two headphones without any in-
teraction from the other output.

There  is  more  than  meets  the  eye  in  working  with  headphones.  One 
reason  for  this  is  that  modern  audio  production  often  necessitates 
decentralized processes. In turn, many musicians or producers might 
wish to – or be able to – mix at home (to say nothing of having to). Then 
the headphone becomes a clear must, enabling an evening or late night 
session that can only take place thanks to its being unhindered by the 
local acoustic environment. 

Now each and every careful headphone user should know about the 
analytical  advantages  of  headphone  monitoring,  but  also  about  the 
main  disadvantage:  the  difficulty  (if  note  impossibility)  in  properly 
judging room ambience.
