Fishman Prefix Pro Blend Preamplifier F.A.Q.

How do I properly install the Fishman Prefix Pro Blend Preamplifier into my acoustic guitar?

To install the Fishman Prefix Pro Blend Preamplifier, ensure the guitar's endpin hole is reamed to the correct size. Mount the preamp's control module on the side of the guitar, then connect the pickup and microphone inputs. Secure the battery and output jack according to the manufacturer's instructions.

What should I do if there is no sound coming from the preamplifier?

First, check the battery to ensure it is charged and properly installed. Verify all connections are secure, including the output jack and input sources. If issues persist, check for any visible wiring damage and consult the user manual for further troubleshooting steps.

How can I adjust the blend between the microphone and pickup on the Prefix Pro Blend?

Use the blend control knob on the preamp interface to adjust the ratio between the microphone and the pickup. Turning the knob towards "Mic" increases the microphone signal, while turning it towards "Pickup" emphasizes the pickup signal.

What is the best way to maintain the battery life of my Fishman Prefix Pro Blend?

To extend battery life, always disconnect the guitar cable from the output jack when not in use, as this activates the preamp and drains the battery. Regularly check the battery level indicator and replace with a fresh 9V battery as needed.

How do I reduce feedback issues when using the Fishman Prefix Pro Blend?

To reduce feedback, first lower the volume and blend controls. Adjust the EQ settings to cut frequencies that are prone to feedback. Repositioning the microphone within the guitar may also help, along with using a soundhole cover if necessary.

Can I use the Fishman Prefix Pro Blend with an external amplifier?

Yes, the Fishman Prefix Pro Blend is designed to be used with an external amplifier. Connect a standard instrument cable from the preamp's output jack to the input of your amplifier. Adjust the preamp settings to suit the amplifier's characteristics.

What are the recommended EQ settings for a balanced sound on the Fishman Prefix Pro Blend?

For a balanced sound, start with the EQ controls set to the midpoint. Adjust the bass, midrange, and treble to suit your playing style and venue acoustics. Use the notch filter to eliminate specific feedback frequencies.

How do I clean and maintain the Fishman Prefix Pro Blend controls?

Use a soft, dry cloth to clean the surface of the preamp controls. Avoid using any liquids or sprays directly on the unit. Periodically check for dust accumulation and gently clean around the knobs and switches.

How can I test the microphone and pickup individually on the Fishman Prefix Pro Blend?

To test the microphone and pickup individually, turn the blend control fully towards "Mic" to isolate the microphone sound, and fully towards "Pickup" to hear only the pickup. This helps in diagnosing issues with either component.

What should I do if the preamp controls become unresponsive?

If the controls become unresponsive, check the battery and connections first. If the issue persists, perform a reset by removing the battery for a few minutes. Reinsert the battery and test again. If the problem continues, contact Fishman support for assistance.
