Using the Mic Input
The second channel includes an XLR microphone input that you can use for miking your acoustic instrument, or for connecting a low impedance vocal microphone. The ACR5 is great for using as a small PA or can make a great vocal monitor thanks to the flat and natural response of its built-in speaker system. Follow these steps for connecting a microphone to the ACR5:
1. Start by turning the MASTER volume all the way down. Connect a low impedance microphone to the MIC/LINE IN jack with a standard XLR mic.
2. Next, raise the MASTER volume to the 12 o’clock position.
3. Now, slowly raise the microphone channel VOLUME control until you add the desired amount of the microphone with your acoustic guitar. Keep in mind that you may need to adjust the acoustic guitar and microphone VOLUME controls to get the best blend between the two channels.
4. For tonal control, the ACR5 features BASS, MID and TREBLE equalizer controls. The BASS control is a shelving EQ, affecting low frequencies around 80Hz, is used to fill out the sound of guitar when playing solo or thin it up when playing with an ensemble. The MID control is a peaking EQ, affecting frequencies around 1.8kHz, which when boosted can help the guitar to cut through to the front of the mix. The TREBLE control is a shelving EQ affecting high frequencies around 15kHz, which can bring out the air or sparkle of the guitar. Setting the BASS, MID and TREBLE knobs to the twelve o’clock position produces a flat frequency response.
5. You can add a splash of chorus or gallons of lush reverb to either input channel using the ACR5’s on-board, 24-bit digital effects, by rotating the CHORUS and REVERB send knobs on each input channel clockwise.
