The sweep CHORUS. Setting it to the best position will minimize both oscillator varies this delay in two ways, from 20 to 24 distortion and noise. The output level does not change at any milliseconds or from 40 to 44 milliseconds. The normal position. chorus delay time is just long enough to create a true stereo image, but the longer chorus delay creates a stronger effect, The HEADROOM LED indicates the level of the signal passing giving the impression that the two sources are independent. through the internal circuitry. The red LED indicates that the level is approaching the distortion point and should not be lit The SWEEP SPEED controller controls a low-frequency too often. If the red LED lights frequently, turn down the oscillator (LFO) for varying the time delay. The frequency of PREAMP LEVEL controller one step. The yellow LED indicates this sweep oscillator can be set from 1 Hz to 0.25 Hz (from the best signal level with the least noise. If the yellow LED one cycle per second to one cycle every four seconds), and does not light up at all, turn up the PREAMP LEVEL controller the speed is indicated by a blinking SWEEP SPEED LED.

If you are connecting a generator, set the PREAMP LEVEL (Please refer to the DIRECT MIXER description.) controller to -6. In either case, watch the LEDs and toggle the switches to find the best operating point. *Maximizing DEEP CHORUS increases the speed to 50%. Note: If distortion is felt even at the -6 position, turn down the level (output) of the effect system used in the previous stage. GOAT BLUE SERIES / STEREO CHORUS...

The apparent volume does not change when switching from chorus to bypass. The 3 dB apparent volume increase that normally occurs when the chorus signal is replaced with a direct signal in the mix is automatically compensated for. GOAT BLUE SERIES / STEREO CHORUS...
- Page 6 Function Description - BLUE SERIES - Principle of Operation The purpose of a chorus is to make a single instrument sound like two or more instruments with well-defined pitch and timing. Just as a string section can be made to sound richer and more beautiful than a single violin with its finely tuned pitch and timing, a guitar or keyboard can be made to sound more lifelike by applying a chorus. The chorus works by splitting the instrument's sound into two different signals. The SWEEP oscillator affects the amount of time delay, which determines the depth of the chorus. The shorter the delay, the higher the pitch of the signal; the longer the delay, the lower the pitch. And the faster the SWEEP oscillator behaves, the faster the delay lengthens or shortens, and the greater the pitch shift. GOAT BLUE SERIES / STEREO CHORUS...
