Sunfire SRS-210R Speaker User Manual


 
User's Manual
1. Standby LED and
2. Power Switch
Press the power switch in to turn on
the amplier. As a general rule, turn it
on after your preamplier or receiver
is turned on. When you have nished
listening for the night, turn it off before
your preamplier or receiver.
After a period of inactivity (i.e. with no
input signal), the amplier will automati-
cally turn itself to Standby mode, where
it is effectively off. It can however, turn
back on automatically when an audio
input signal is present, if a 12 VDC
trigger voltage is applied to the Trigger
inputs, or if the Start button is pressed.
3. Start button
Press this once to enter the Auto EQ
mode (if the sub is out of Standby
mode). Press and hold it down for
several seconds to enter the Manual
EQ mode. See page 12 for more de-
tails on this and the EQ controls.
4. LED display
These LEDs are used during the Auto
EQ and Manual EQ procedures.
5. Microphone Input
This is where you plug in the supplied
linear measurement microphone when
you want to use the Auto EQ mode.
(Only use the supplied microphone.)
6. Equalizer Authority
This control's primary purpose is to
adjust the EQ Authority. During normal
listening, you can adjust the overall EQ
from none (ccw, 0%), to fully equalized
(cw, 100%). For example, if your rst
band has a 6 dB boost, setting this
control to 50% would make it boost
only 3 dB.
This control is also used during the
Manual EQ mode to adjust each of the
four internal EQ bands, and allow you
to add "color" to the sound as desired.
7. Phase Control
This control changes the relative phase
of the subwoofer with respect to your
other speakers. Use this control to help
blend the subwoofer with the rest of
your system. This is accomplished by
adjusting the control in small incre-
ments as you listen for the most bass
at your listening position. As a nal trim,
readjust the Crossover Frequency and
Volume controls after the Phase has
been set.
8. Crossover Frequency
This controls the high frequency cutoff
point. With the control at the 100 Hz
mark, the subwoofer will reproduce
frequencies up to 100 Hz. If the control
is set fully clockwise, the crossover
is bypassed and the subwoofer will
reproduce a frequency range up to
115 Hz. With the control fully counter-
clockwise the subwoofer reproduces a
narrow range, up to 30 Hz.
