2 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.
