BLOCK DIAGRAM
6. CHANNEL EFFECTS/REVERB LEVEL CONTROL
The EFF/REV level control adjusts the volume of the channel going to the effects send master control, and the internal reverb tank. The effects control is post channel level. This means adjustments in the channel’s EQ or level con- trols will be affecting the effects send of that chan-
nel. |

is a band pass type of tone control with the center | 0 | 1 0 |
frequency set at 1.5KHz. The band pass means a
middle section of frequences centered around 1.5kHz, but not over lapping the HI and LO controls, is boosted when the knob is turned clockwise and cut when turned
Familarity with the channel tone controls:
The three tone controls can add brightness, clairity, and control to the channel’s input signal. Here are some tonal references for these tone controls.
•LO affects the deep low bass tones and the typical bass tones.
•MID affects all the middle frequencies where the clairty of an average persons spoken voice is mostly heard. Also the MID incompases the louder sometimes harsher tones that can distort the over all sound of the system.
•HI affects the treble tones and very high treble tones bringing brightness and brillance to the channel’s input.
Adjusting:
Use these controls to change the tonal shape of the input signal and in many cases to reduce possible feedback from microphones near the mixer’s output speakers. It is suggested the channel tone controls start out in their center detent position where they do not effect the original incoming signal. Then, if needed, turn the tone controls (boost,turn to the right, or cut, turn to the left) to change the sound.
