CA125D Acoustic Amplifier About the Crate Acoustic CA125D: D esigned for the performing artist, Crate’s CA125D 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: twin 50-watt RMS power amplifiers drive a pair of specially designed high fidelity 8” low frequency transducers for plenty of volume and low end punch.
CA125D Acoustic Amplifier The Front Panel: 1 2 3 15 4 5 6 7 16 17 18 8 9 10 11 12 13 14 19 20 21 22 23 24 The Instrument Channel: 1: Input. The signal output from your acoustic instrument may be connected here by means of a shielded instrument cable. 2: Active/Piezo. Use this switch to match the type of pickup used in your instrument. For active electronic pickups, set the switch to “active” (switch out). For passive/magnetic pickups, set it to “piezo” (switch depressed). 3: Gain.
CA125D Acoustic Amplifier The Rear Panel: 36 28: Footswitch. Connect the supplied two-button footswitch here for remote on/off control of the internal reverb and chorus. (When connected, the footswitch overrides the front panel chorus on/off switch.) Note: This is a STEREO jack: tip controls the chorus, ring controls the reverb, sleeve is ground. Use only a footswitch equipped with a stereo 1/4” plug. 29: Effects Loop Send.
CA125D 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.
CA125D Acoustic Amplifier The Tilt Back Feature: There are instances when you may need to tilt the amplifier back to better project its sound towards your ears (as a nearfield monitor) or towards your audience (for better coverage). The CA125D features a tilt back device underneath its cabinet for this purpose. To utilize this tilt back feature, refer to the illustration below and follow these simple steps: 1 Carefully lean the cabinet back until the front of the cabinet is several inches off the floor.
