You asked for
it. Your band asked for it. Your clients asked for it. Your mom
practically asked for it.
Since the dawn of computer-based music making, folks have longed
for a simple monitor switching and level control box with built-in
Talkback functions. You know, something that sits right on your
desktop, letting you easily switch between sets of studio monitors
and different stereo sources. And send musicians custom headphone
mixes while you communicate with them via a built-in Talkback
microphone. Your wish is our command...

Introducing The Big Knob
The Big Knob is a simple yet powerful desktop audio control center
that lets musicians and engineers get right to the business of
making music in four major ways: Level Control, Studio Monitor
Selection, Input Source Selection and Talkback & Headphone
Control.
Precise Level
Control
Using a big, convenient volume knob, Big Knob lets you adjust
volume levels the way our ancient audio ancestors (Analogus
Engineerus) did - with a simple, intuitive knob, not with a mouse
and screen. The end result is a higher degree of precision and much
quicker level adjustments.
Monitor
Selection
When it comes to mixing, pros know it’s best to get a second,
and third, opinion. So Big Knob lets you quickly switch between 3
pairs of studio monitors, or 2 studio monitors and a subwoofer, or
studio monitors and a home stereo, or any other combination of
powered speakers.
Source
Selection
On the input side, Big Knob lets you connect up to 4 stereo input
sources at once. This means you can simultaneously connect to your
computer/DAW outputs, CD player, cassette deck and even a turntable
using the premium onboard RIAA preamp. You can even connect
keyboards, guitars, drum machines, samplers - anything you’d
like to hear - through your monitors. This makes Big Knob great for
comparing your mixes-in-progress to your favorite CDs, for
archiving your old LPs, jamming along to your favorite tune, and
lots more.
Talkback
Section & Headphone Control
With its built-in Talkback mic and spring-loaded activation
switches, Big Knob lets you quickly communicate with musicians in
both the studio and tracking room - no more hand signals through
the glass! Big Knob also sports two high-powered headphone outputs
with a discrete headphone mix bus, solving the communications needs
of most computer-based studios.
All the Right
Connections
Although its shiny silver knob is a head-turning feature, Big
Knob's rear panel is equally impressive. There you’ll find
three distinct Monitor outputs with individual level control;
2-Track A and 2-Track B stereo outputs with level selection
switches; a DAW stereo output for your computer; a Studio output
with level control; a Phones Mix input with level selection switch;
2-Track A and 2-Track B Stereo Source inputs with level control; a
DAW Mix input from your computer with level control; and even a
Phono input with level control for direct connection to your
turntable.
Sound
Quality
Because Big Knob plays a crucial link between recording output(s)
and studio monitors, we placed the utmost importance on pristine,
no-compromise sound quality. For this reason, Big Knob features
ultra low-noise op amps, extremely low-tolerance components and
state-of-the-art surface mount technology. All of this ensures
superb sound in critical listening environments and long-term
reliability - even under daily, and nightly, studio
use.
