2Control

Headphone Volume Controls 1 and 2

With these two detended controls you regulate the amplification of

the headphone signals. Output and amplification specifications allow

operation with a wide variety of headphones from ranges 30 to 600

Ohms. The 2Control provides two separate headphone amplifiers. This

excludes mutual influences while VOLUME controls are independent

from each other as well as from speaker volume. For further details on

connecting headphones please refer to “Headphone Connection“ on

page 15.

Optimal Control Range of the Potentiometers

The control range of the headphone volume covers a very large band-

width in order to provide a production tool that simply works with all

headphones. You can listen to loud levels with 30 Ohm headphones and

you can “zoom” into quiet passages with 600 Ohm headphones. In order

to achieve this large bandwidth, we can not guarantee that the poten-

tiometers run with perfect left/right alignment already at the very first

few clicks. This is component-related and no design flaw or damage. A

reduction of overall amplification would decrease audible tolerances at

the start of the control range, but it also would reduce the overall am-

plification which may be needed when listening to low level signals in a

mix. Use the control range above scale position “1” for critical listening

to remain within the optimal control range of the potentiometer.

Protect your Hearing

Always reduce volume before you put on headphones or before you re-

move or plug in the headphone. This excludes louder clicks and pops

reaching the ear. In addition, this can avoid unpleasant surprise that

follows when a headphone’s lower impedance suddenly reproduces a

much higher – even painful – level.

Always take care of your hearing when monitoring – especially with

headphones. Reduce volume all the time as far as possible and expose

your hearing to higher volumes only for short periods. As an orienta-

tion: German laws oblige ear protection in the professional area if the

hearing is exposed to more than 85 dB sound pressure level – this level

can already damage the hearing in the long term.

The 2Control can produce sound pressure levels that may be danger-

ous for your hearing because the large impedance scale of headphones

requires a large performance range. Always regulate volume by start-

ing from the zero position especially when you start working or switch

headphones.
