Once your Whise 1500 HD-A
®
loudspeaker are in a position you are comfortable
with, you should spend some time adjusting the bass and treble to suit both the
room you are in, and your own personal preference.
The best way of achieving this is to select a recording that you are intimately
familiar with, such as a favorite song. Select music that has a broad range of
frequency components so that you can judge where to set each of the knobs
more effectively.
Imaging
The first thing to check is that the stereo image is even and coherent. Make sure
that the components of the track such as vocals, different instruments etc are in
the places they should be within the stereo image as if you were listening to the
song on headphones.
This is especially important if you have never listened to electrostatic speakers
before, because they create a more precise, detailed and wider image compared
with conventional electromagnetic cone speakers.
Once you are satisfied that the audio imaging is correct, listen to the various
frequency components with the knobs all set to 12 o’clock.
Brightness
Now you should adjust the room brightness to your taste. It is not uncommon for
this to be somewhat lower than the normal, especially if you have a lot of
reflective surfaces in
the room. The best way to test is to clap your hands. The echo you hear is the
time delay effects and room resonances, and so this adjust feature lets you
compensate for that.
Adjust the knob until it sounds natural to your ears.
Now listen to the track with frequency adjust knobs set to their extremes, one at a
time. First set the 80 Hz adjust knob all the way up and listen, and then all the
way down and listen. Repeat this with the 250 Hz adjust knob. This will help to
give you a feel for the limits of the adjustment, and give you some idea as to
where you would prefer to listen.
Absolute Phase
If you are using your own power amplifier to connect to the Whise 1500 HD-A
®
loudspeaker, you might want to experiment with Absolute Phase. This is a much
