Phones
The Crimson has two independant high-quality headphone amplifiers. Use volume con-
trols Phones 1 and Phones 2 to adjust the level of the headphones signal. Thanks to
the separate headphone amplifiers there is no risk of any interferences when connect-
ing two headphones. The outputs and gain ranges are designed for headphones with
impedances from 20-600 ohms.
For more details regarding the connection of headphones, refer to “Phones 1 and
Phones 2” on page 18.
Optimal Potentiometer Control Range
The control range of the headphone amplifiers is very wide: it allows you to listen to very
high level signals with 30 ohms headphones, as well as to detect the faintest details
in quiet passages with 600 ohms headphones. To achieve such a wide range, and due
to component characteristics, a constant taper during the beginning of the travel of the
potentiometer cannot be guaranteed. A reduction of the overall volume would also lower
the tolerance in this initial range, but at the price of wasting power margin. Thus, we
recommend you to adjust the level above the “1” mark to achieve best results.
