The Amplifier

All the functions described in this chapter apply to the amplifier section of the K1 AV. They are available for all source
devices, i.e. both for the integral disc player and tuner and also for external machines connected to the receiver.
The basic amplifier functions can be controlled directly using the buttons on the front panel or those on the remote
control handset. Seldom required functions such as the Balance and Tone controls are grouped together in a Setup
menu (‘Amplifier menu’).
Basic settings, which are generally only required once when the K1 AV is installed, are adjusted using th e Amplifier
Setup menu; see chapter ‘Basic settings / Installation / Using the K1 AV for the first time’.

Basic functions

Switching on
The K1 AV is switched on and off using the On / Off
button () on the front panel or on the remote
control handset.
It can also be switched on directly using any of the
source buttons on the remote control handset ( /
/ / / ).
Selecting a listening source
Select the desired listening source with the
button on the front panel, or using one of the source
device buttons on the remote control handset.
Volume
The volume can be set either on the machine or using
the VOLUME buttons on the remote control
handset.
A brief press on the buttons changes the volume by one
increment (1.25 dB). Holding the button pressed in
causes the volume to change continuously.
The K1 AV features loudspeaker outputs for two
listening rooms or zones. The volume can be
set separately or in common for both zones (see
chapter 'Multi-room mode').
Surround mode
The K1 AV is equipped with an analogue room
sound processor. Basically it can be operated with
two or three loudspeakers in the main room. Three
speakers (Left / Centre / Right) provide a more
natural and spacious playback overall, eliminating
the ”acoustic hole” in the middle. When you are
playing a film, the third speaker also helps to
localise speech and sound events on the screen.
If the K1 AV is operated with two loudspeakers
(left / right), then only the STEREO mode is
available.
If a Centre loudspeaker is present, the K1 AV can be
switched between the playback modes STEREO, 3-CH
MUSIC and 3CH MOVIE by repeatedly pressing the
button on the remote control handset.
For music playback we recommend the modes STEREO
or 3CH MUSIC, and for film playback the mode 3CH
MOVIE.
The K1 AV remembers the surround mode you last used
for each source, and reverts to it next time you switch to
the same source. For example, if you select ‘STEREO’
for the tuner, then the K1 AV automatically reverts to
stereo mode next time you select the Tuner source.
DVDs can also be played optionally in Virtual
Surround mode (see chapter 'The disc player /
Player setup menu / Audio setup menu'). If you
activate Virtual Surround for the disc player, you can
use the button to select whether the sound
is to be reproduced via two or three loudspeakers.
MONITOR
The MONITOR function of the K1 AV is designed to
allow you to monitor the recording process when using a
tape or cassette recorder, provided that your recorder
features a ‘tape monitor’ button.
If you wish to make a recording, select the source device
to be recorded as described under ‘Select listening
source’. Start the recording process on your recorder.
A long press on the button now switches to the
recorder’s tape monitor signal while the recording
continues. In this way you can check the quality of the
recorded signal while the recording process is still under
way.
When you switch to tape monitor the screen of the K1 AV
briefly displays the message ‘MONITOR’, and the
monitor indicator lamp lights up.
To halt the monitor function, press the button
again briefly. For a moment the screen displays the
message ‘SOURCE’, and the monitor LED goes out. You
are now hearing the direct signal of the source device
again.
If you switch the monitor function on when there
is no audio recorder with monitor facility
connected and set to record mode, the
loudspeakers will be muted.
