CONTROLS AND THEIR FUNCTIONS
FRONT PANEL
Volume control: regulates maximum outputs on headphone outputs.
Impedance selector: optimizes amplifier’s performance for wide range of headphones.
As a general rule, select the impedance that is the best match for the headphones that are being
used. It is possible to use different impedance setting, as that will result in slight changes in the
sound. While high impedance headphones can be used with the low impedance settings; for
example, 300 ohms headphones can be used with Primavera set to 50 ohms, however, it is not
recommended that low impedance headphones are connected to the high impedance setting -
using 40ohm headphones with 300 ohm setting will results in loss of resolution and increased
distortion.

Power ON/OFF switch: The switch turns the amplifier ON and OFF
When turning on the amplifier, make sure that the volume control is at its minimum. The am -
plifier will be fully functional after only 30 seconds. However, as it warms up over the first 15
minutes of operation, you may notice subtle improvements in the sound quality.
At the end of your listening session, make sure to turn the amplifier off. Leaving it turned on
does not improve sound quality and it reduces life of the vacuum tubes.
The amplifier should always be turned on and off via its own power switch.
