Both models combine a dedicated guitar channel with an independent microphone channel, allowing one performer to amplify an acoustic instrument and vocal microphone through a single system.\u003C\u002Fp>\n  \u003Cp>The ACS-LIVE delivers a 60-watt bi-amped design with a 6.5-inch woofer and dome tweeter, while the ACS-PRO provides 120 watts with a larger 8-inch woofer for greater headroom and projection. Each channel includes a three-band equalizer, level control, anti-feedback facilities, and effects suited to acoustic performance. The guitar channel includes Acoustic Resonance processing to help restore a more natural response when using piezo pickups. The microphone channel supports phantom power for compatible condenser microphones.\u003C\u002Fp>\n  \u003Cp>Additional performance tools include guitar chorus, vocal delay or echo, reverb, harmony generation, and a built-in looper. Separate XLR outputs support connection to a mixing console, audio interface, or recording system. USB connectivity and a headphone or recording output also make the amplifier useful for practice and direct recording.\u003C\u002Fp>\n  \u003Cp>Choose the ACS-LIVE for rehearsals, coffeehouses, teaching, and intimate venues.

Connect your acoustic guitar to the GUITAR input and a microphone to the MIC input if needed. Connect external audio to AUX IN, plug in the power cord, and switch the amplifier on. Raise the channel volumes gradually while adjusting gain, equalization, chorus, reverb, and master volume to suit the room.",{"question":143,"answer":144},"Why is my BOSS ACS-LIVE & ACS-PRO Acoustic Amplifier producing feedback?","Acoustic amplifier feedback usually occurs when the microphone or guitar is too close to the speaker, the volume is excessive, or certain equalizer frequencies are boosted. Move the microphone behind the speaker’s front axis, increase the distance between the guitar and amplifier, and reduce the channel or master volume. Use the anti-feedback controls where available, and lower bass or midrange frequencies carefully instead of cutting the entire signal.",{"question":146,"answer":147},"How can I connect a microphone and acoustic guitar at the same time?","The BOSS ACS-LIVE & ACS-PRO Acoustic Amplifier has separate microphone and guitar channels, allowing both sources to be used simultaneously. Connect the microphone to the MIC combo input and the guitar to the GUITAR input. Set each channel’s gain and volume independently, then balance the vocal and instrument with their channel controls. Apply vocal effects only to the microphone channel and guitar effects only to the guitar channel when required.",{"question":149,"answer":150},"How do I use the built-in looper on the BOSS ACS-LIVE & ACS-PRO?","The built-in looper can record and replay performance layers from the guitar and microphone channels. Connect the appropriate foot control, select the looper function, and start recording with the assigned footswitch. Play the phrase clearly, stop recording at the correct point, and trigger playback hands-free. Keep the loop phrase rhythmically consistent, and adjust the looper level separately so it supports rather than overwhelms your live guitar or vocal.",{"question":152,"answer":153},"Can I connect the BOSS ACS-LIVE & ACS-PRO Acoustic Amplifier to a mixer or recording system?","Yes. The amplifier provides dedicated DI or line outputs for sending microphone, guitar, or mixed signals to a mixer, audio interface, or recording system. Use balanced XLR cables where appropriate and begin with the receiving device’s input gain turned down. Choose the output that matches your routing needs, then raise levels gradually while monitoring for clipping. The PHONES\u002FREC OUT connection can also support silent monitoring or recording applications.",{"question":155,"answer":156},"What should I check if there is no sound from my BOSS ACS-LIVE & ACS-PRO?","First confirm that the power indicator is on and the master volume is raised. Check that the guitar cable or microphone cable is fully inserted into the correct input, then verify the channel volume and mute status. Test another cable and input source if possible. If headphones are connected, remove them because they may redirect or interrupt speaker output. Also confirm that AUX IN playback is active and its source device is producing audio.",{"question":158,"answer":159},"How do I reduce unwanted noise or distortion from the acoustic amplifier?","Keep instrument and microphone cables away from power adapters, lighting cables, and other potential sources of interference. Reduce the input gain if the sound becomes harsh or distorted, and avoid setting every equalizer control to maximum. Check whether the connected guitar has an active preamp with a weak battery, since a low battery can cause distortion or intermittent output. Use balanced XLR connections for longer output runs and keep the receiving mixer below clipping.",{"question":161,"answer":162},"How should I maintain and store the BOSS ACS-LIVE & ACS-PRO Acoustic Amplifier?","Turn the amplifier off and disconnect the power cord before cleaning or moving it. Wipe the cabinet with a soft, dry cloth, and keep liquids away from the control panel, speaker grille, and connectors. Do not block ventilation openings or store the unit in damp, dusty, or extremely hot locations.
