A-9030/9050-Using the Integrated Amplifier as a Preamplifier

The integrated amplifier can be used as a preamplifier (Pre mode). This is an example of connection using the power amplifier (A-9050 Only).

If there is no sound:

• Make sure the integrated amplifier’s volume control is not set to minimum
• Make sure the correct input source is selected
• Make sure the integrated amplifier is not muted
• Make sure the speakers are connected correctly

If the sound is distorted or sound quality is not good:

• Make sure the speaker cables are connected with the correct polarity
• Check that the switch on the back of the integrated amplifier is set to the correct setting.
• Make sure all audio connecting plugs are pushed in all the way
• The sound quality can be affected by strong magnetic fields, such as those from a TV. Try moving any such devices away from the integrated amplifier
• Using cable ties to bundle audio cables with speaker or power cables may degrade the sound quality, so refrain from doing it
• Plug the power cord into an AC wall outlet
• Install the integrated amplifier on a sturdy rack or shelf. Position it so that its weight is evenly dispersed on its four legs. Do not install the integrated amplifier in a place with vibration or an unstable location.
