2. Connecting the de ice
Myth Preamplifier is intended for use in close and dry environment.
Surrounding of the device must be clean and dry.
The operating temperature is from 5 C to 50 C. Storage temperature is
from -10 C to 0 C.
The device is using city AC power network 240V/50Hz.
The device is protected with the fuse of 1.1 A at the primary of the
mains transformer. In case of necessity, the fuse should be replaced only
with the appropriate type for 1.1 A (F 1.1 A)
The backside switch puts the device in stand-by state.
The control lamp on the switch indicates that the mains cable contains
a proper grounding. In the case the lamp is off it is recommended to
check the grounding connection of the mains cable before using it.
Device chassis is grounded via mains cable. Analog grounds of RCA
connectors are not grounded.
It is recommended to avoid connecting and disconnecting RCA cables
while the device is turned on. This may cause noise and interference to
the power amplifier, thus making unpleasant noise on the system
speakers. The safest way to connect RCA cables is to completely power off
the device and then to attach desired connectors.
The back panel of the Myth Preamplifier provides five stereo line inputs
and one stereo line output.

3. Turning on the de ice
After connecting the device to 240V AC, turn on the switch on the back
side of the case. LED on the mains switch indicates that a proper
grounding is applied to the casing of the unit. If the LED stays off after
the mains cable has been connected, it is probably due to bad grounding
or cable defect. The device is still operational, but keep in mind that the
metal casing is not grounded anymore.

5. Using Touch Screen
The surface of the Touch Screen is intended to be used by soft and
gentle tools such as finger, soft plastic pointers or similar. Any use of
sharp and hard pointers such as sharp pencil, finger nail, screwdriver etc.
can cause a permanent damage to the screen.
Operation force needed to cause action on the Touch Screen is from 20g
to 80gr. Response time of the touch panel is less than 30ms.
The Touch Screen surface of the display is divided into six logical
sections:
1. Previous Input
2. Next input
3. Toggle Menu
4. Volume Down
5. Volume Up
. Mute/Unmute
Touching any of the sections
invokes appropriate function.
5.1. To select input using Touch Screen
Touching the area "Previous Input" the input selection changes in the
following order:
AUX - PC - TUNER - DVD - CD
Touching the area "Next Input" the input selection changes in the
following order:
CD - DVD - TUNER - PC - AUX
Note: The names of the inputs may differ due to customization and user
preferences.
5.2. To set olume using Touch Screen
Touching the area "Volume Down" the volume decreases down to zero
in steps of one.
Touching the area "Volume Up" the volume increases up to 99 in
steps of one.
Note: Depending on the input sensitivity of the power amplifier and of the
speakers, volume levels should be considered relative to the system. For
e ample, the volume level of 68 may be louder on some more sensitive
speakers, while it may sound quieter on some less sensitive speakers.
