Frequently Asked Questions - KMA-980 YAMAHA
How do I connect microphones to the Yamaha KMA-980?
Use the two 1/4" TS mono microphone inputs. Insert each microphone cable firmly into the mic jack, then adjust the microphone volume and echo level to avoid feedback.
What speakers can I use with the KMA-980?
Connect speakers with an impedance of 8 ohms or higher to each channel. The amplifier delivers up to 110 W RMS per channel, so choose speakers with adequate power handling.
How do I adjust the echo effect for vocals?
Turn the echo level knob clockwise to increase the effect and counterclockwise to reduce it. Start low and adjust until the voice sounds natural.
Can I play music from my smartphone?
Yes, connect your smartphone to the auxiliary input or one of the RCA line inputs using the appropriate cable, then select the corresponding input source.
How can I prevent microphone feedback or whistling?
Keep microphones away from speakers, reduce the microphone volume, and lower the echo level. Placing the microphone behind the speakers also helps reduce acoustic feedback.
How should I clean the KMA-980?
Unplug the unit and wipe the exterior with a soft dry cloth. Do not use water, alcohol, or abrasive cleaners on the chassis or controls.
What should I do if there is no sound despite power being on?

Can I operate the KMA-980 without a remote control?
Yes, all essential functions are accessible from the front panel controls, including volume, tone, echo and input selection. If your unit came with a remote control, it simply adds convenience.
