Orion COBALT Series Installation Manual

SETTING UP YOUR COBALT AMPLIFIER
After completing the steps listed in the Installation section, you are ready to set the amplifier's
Input Gain and perform final system checks.
Setting Input Gain
1. Turn the vehicle's lyiitioJi Switch to the ON position.
2. Turn the OWOff Switch on the Control Head Unit (or Radio) to the ON position.
3. Select a known stereo FM station with a strong signal for the following tests. Make sure all Tone or Equalization con¬
trols are left in the ‘flat' position, and any Loudness button is out of circuit
4. Observe that the POWER indicator on the Cobalt amplifier lights.
5. If the system indudes an Equalizer like the 300 PHD, set all frequentry controls to “flat" position, and then turn its over¬
all gain to mannwin level.
6. Slowly irxrease the GAIN Control on the amplifier, until you hear slight clipping. At this point the amplifier is calibrated
for maximun dynamic range without distortion. (On the CO 430 amplifier adjust the Front GAIN Control, and then
adjust Rear GAIN Control.)
FINAL SYSTEM CHECKS
t. Start the engiie atvJ turn the ONIOFF Switch on the control head unit or radio to the ON position. Slowly increase the
Voluffle Control to about the 10 o’clock position and listen to the audio reproduction. The sound level should slowly
ramp up over two seconds to the setting you've picked. The sound you hear should be clean and solid. If you hear any
noise, static, distortiots, or no sound at all, go back over the connections listed In the Installation section, and also refer
to Troubleshooting Guide (see page 2S).
NOTE: Depending on the system design, the sound kvels may become quite loud even at low
Volume Control settings. Use restraint when first positioning control until you get an "audio feel"
of the system's reproductive power.
2 . Turn the Balance and Fader Controls to their extreme positions and listen to the corresponding results. The sound
should trark the action of the control. If not there may be a polarity mix-up somewhere in the wiring. Check the
Troubleshooting Guide at the back of this manual.
3. Inaease the Volume Control and verify that the Cobalt Amplifier provides the desired volume at full frequencies with¬
out distortion. It you hear distortion, check theconnectionsand verify that the GAIN Glibration is correct. Another pos¬
sibility is damaged or under-rated speakers. Once again, check the Troubleshooting Guide for additional help.
