Custom Sound Tailoring
Controls, ERT/ERM speakers
•
Switchable tweeter level adjustment
(ERT-8.3/ERM-6.3/ERM-6.2/ERM-1)
This switch provides a total range of 4dB of adjustment to the tweeter level with positions of 0dB, -
2dB, and +2dB. Begin in the 0dB (neutral) position. By switching to the +2db or -2db settings, you
can create a brighter or warmer sound to compensate for room acoustics or personal preference.
•
‘Extension’ adjustment
(ERM-6.3 & ERT-8.3)
In addition to the tweeter level adjustment, ERT-8.3 and ERM-6.3 speakers have an ‘Extension’
control. On the ‘Low’ setting, a standard EQ curve is in effect with frequencies above 18kHz
beginning to gently roll-off. On the ‘High’ setting, the frequencies above 18kHz are extended
creating a brighter and ‘airy’ sound that may be used to counter room acoustics or personal
preference.
•
Switchable midrange level adjustment
(ERT-8.3/ERM-6.3)
This switch provides a total range of 4dB of midrange adjustment with positions of 0dB, -2dB, and
+2dB. Begin in the 0dB position. By switching to the +2db or -2db settings, you increase or
decrease the midrange response to the smaller woofers.
•
Switchable boundary effect compensation
(ERT-8.3/ERM-6.3/ERM-6.2, ERM-1)
This is used to reduce the upper bass range of the speaker. If it is mounted close to a wall, inside a
cabinet, or near a large piece of furniture or other ‘boundary’, the upper range of the bass (300-
500Hz) can become more prominent and create an unpleasant ‘booming’ sound. Flipping the
switch to the ‘On’ position compensates for this condition by reducing 400Hz by about 10dB.
Selectable Bi-pole /Di-pole Selection Controls, ERD-1 speakers
Use these switches in combination to select whether the speaker will function as a left channel
dipole, right channel dipole, or a bi-pole configuration in or out of polarity with either left or right
channel orientation. Detailed description of Bi-pole/Dipole controls: page 11
