Adjusting The Input Sensitivity; Adjusting The Bass Eq - RoDEK RN-1600 Installation Manual

5.5 ADJUSTING INPUT SENSITIVITY
To reach a maximum noise-free dynamic headroom from each
individual head unit/amplifier/speaker combination, it is impor-
tant to set the respective input gain controls correctly. The input
level settings determine the actual signal-to-noise ratio, and they
are also responsible for obtaining the maximum distortion-free
SPL (sound pressure level) from your specific setup.
Turn-on your head unit and set the volume control to approxima-
tely 3/4 of full volume, while playing a dynamic track from a CD.
Slowly increase the LEVEL adjustment control of the channel pair
section to which your subwoofer system is connected to. Turn
up the (sub channel) level control knob until you can just about
hear distorted bass sounds. Now you reduce the volume level
of your head unit to a "normal" listening level and "add" all the
remaining channel pairs, but turning up the corresponding level
controls – aiming for a balanced sound with a slight emphasis
of the bass range. All remaining channels, no matter if this con-
cerns rear mounted coaxials, component- or kickbass systems
installed in the front doors – must be balanced against the main
level setting of your subwoofer. Usually, it's best to start with the
level adjustment of the front door mounted speaker system.
5.6 ADJUSTING THE BASS EQ CONTROL
The bass EQ control of your RODEK amplifier can be adjusted
with the e-pot to "push" the 45 Hz center frequency from 0 dB
to 10 dB. The bass EQ will increase the perceived low end re-
sponse of your amp woofer combination – but it will also reach
the max. output of the respective channel earlier. With a bass
EQ adjusted too high, most speakers can be overdriven easily.
Thus, this setting should be attempted with care.
