CA6110D Acoustic Amplifier About the Crate Acoustic CA6110D: D esigned for the performing artist, Crate’s CA6110D Acoustic Amplifier gives you more of what you want. More power. More clarity. More control. And, more freedom. Imagine: microphone quality sound, without feedback. And without being “chained” to a mic stand! More power: a 60 watt RMS power amplifier drives a 10” polypropylene woofer for plenty of volume and low end punch.
CA6110D Acoustic Amplifier The Front Panel: 1 2 3 4 5 6 7 NOTE: Channel 1 and Channel 2 are independent of each other up to the Effects and Master sections. The text below (#1–8) applies to both channels. 1: Input. The signal from a low impedance microphone or your acoustic instrument may be connected here by means of a shielded, balanced microphone cable terminated with an XLR connector or a shielded signal cable. This combo jack has 15 volts phantom power applied to XLR pins 2 and 3.
CA6110D Acoustic Amplifier The Rear Panel: 16 17 16: Power. Use this switch to turn the amplifier on (top of the switch depressed) and off (bottom of the switch depressed.) The power switch illuminates when the amplifier is on. 17: External Speaker. Use this jack to connect the amplifier to an external speaker cabinet. This jack is wired in series with the internal speakers which remain active when an external speaker is connected. 18: Feedback Filters Footswitch.
CA6110D Acoustic Amplifier To Eliminate Instrument Feedback: One of the most common problems encountered when amplifying acoustic instruments, especially in small environments, is feedback. Acoustic instruments typically have inherent qualities which cause resonant feedback at specific frequencies. Instrument tone controls and sound board equalizers are helpful in getting rid of the problem, but they typically operate around relatively wide frequency bands.
