Variable Knob Setup; Display - Halcro dm10 Owner's Manual

Variable knob setup

There are three ways
continuously variable knobs (Fig 3, 1 and 2)
• according to the manufacturer's
recommendations
The actual load capacitance of the
cartridge should be set to the value
recommended, minus the capacitance of
the interconnect between the phono-
stage and preamplifier.
• by using test instruments
This requires an oscilloscope and a test
record that includes tones at several
different frequencies between 10 and
20 kHz or a swept frequency that includes
20 kHz. The oscilloscope should be
plugged into the preamplifier tape output
and the level noted for different
frequencies above 10 kHz. Knobs should
be empirically set for flattest frequency
response.
• empirically by ear, so long as you can hear
up to 20 kHz!

Display

of setting the
Displayed information
In normal use the center of the display will
display the volume of both the left and right of
the system. When a different signal source is
selected, it will appear in the center of the
display for a few seconds (Fig 2).
Display contrast
To adjust the display contrast, press and hold
any of the Program buttons on the rear panel
(Fig 3, 8) and turn the Volume control on the
front panel until the desired contrast is
achieved.
Back light
The backlight can be turned on and off by
using the remote control. Press the function
button once (Fig 4, 5) then the Mute button
(Fig 4, 2) to toggle the back light on and off.
