Stereo Equalizer User Manual

Owner’s Manual
Congratulations on your purchase. We trust that you will enjoy the value and quality of your AudioSource EQ Eight/Series II
for many years. To ensure the best performance from your unit, please take a few moments to read this manual. Also, be sure
to retain this document for future reference.
BASIC GUIDELINES
A graphic equalizer is a powerful tool for very detailed control over the sound of your speakers. Before adjusting the sliders, it
is very important to clearly define your objectives. Carefully listen to your system and ask yourself what you'd like to change
about its sound. If you want more bass, for example, either raise the sliders for the lowest frequencies or lower the sliders on
the midrange and higher frequencies. Do this for both the left and right channels. Conversely, if you'd like to hear more high
frequencies, either raise the sliders for the highest frequencies or lower the midrange and bass frequencies.
USING THE CONTROLS
Power
Press this button to turn the power on the unit on or off. The red LED will light to show power is on.
EQ Rec.
Press this button to record with the equalization curve you have just set. This can be useful when making a cassette tape to
play in your car. With this button in the off position, the copy will be recorded without equalization.
Monitor
Press this button to hear the sound from your cassette deck. Your deck should be connected into the tape in and tape out jacks
on the rear panel of the EQ 8/Series II.
Audio/Video
This button selects between audio (such as CD) or video (such as DVD or VCR) input sources. To select audio, press this button.
To select video, do not press this button. The red LED will be lit only when audio is selected. Of course, the EQ Eight/Series II
equalizes only sound; at no time does the EQ Eight/Series II alter any picture, and no video-type connections are included.
EQ/Pass
Use this switch to instantly compare the equalized and unequalized sound. Press this button to hear the equalized sound. The
red LED will light to show this selection. Leave this switch in the out position to hear the unequalized sound.
EQ Sliders
There are ten sliders per channel (ten for the left channel and ten for the right channel). The lowest frequency sliders are on
the left, the highest frequency on the right. Usually, identical adjustments should be made for both channels. Each of these
sliders has a range of 12 dB to boost or cut its particular frequencies.
These sliders are one octave apart from one another. This corresponds with the entire range of human hearing. The last page
of this owner's manual contains a chart, showing which sliders to adjust to affect the sound of various instruments. For
instance, the lowest note of a bass guitar is around 42 Hz. Adjusting the sliders at 30 Hz and 60 Hz can adjust the volume of
the bass guitar, bass drum, and any other musical instruments that occupy this frequency range.
Spectrum Analyzer Display
This provides a visual display for you to monitor the relative signal levels in each of the EQ sliders. The spectrum analyzer
display is divided into ten columns of LED's which correspond to the ten EQ sliders.
