MASTER CONTROL PANEL FUNCTIONS LEFT RIGHT A A MASTER REV B SYSTEM EQ C A. MASTER OUTPUT LEVEL CONTROLS The Left and Right Master Controls route the mix busses to the internal power amplifiers. Passport's internal amplifiers have on-board processing designed to optimize the system performance. When used with speakers other than those supplied with the system, the processing will be apparent. This may, or may not be desirable, depending on the characteristics of speaker systems used. Normally the sound of any speaker is enhanced by the Passport processing. For the majority of applications the Passport system has been balanced to operate with these controls at their notched 12 o'clock positions. In situations where more "gain" is required, for example where a microphone (s) is at some distance from the user and more volume is required than can be reached with the input channel level controls, the master controls give an additional 6 dB of gain. Set the system up in the normal manner and adjust levels as necessary. Should more overall sensitivity be required the master controls can be raised. Care should be taken to avoid feedback, or howling. The Master controls feature notched position indicators. If possible always operate the Master controls in their notched position. Should the overall mix level need to be increased or reduced when the system is set up and balanced, the Masters can be rotated to any position that works under the circumstances. B. MASTER REVERB - Adjusts the amount of reverb signal level sent to the mix or output. Rotating the knob clockwise increases the reverb signal sent to the main mix. When the knob is in its full counterclockwise position, there is no reverb heard in the mix. C. SYSTEM EQ - Adjusts the overall amount of frequency increase or decrease on the Passport. Rotating the knob counterclockwise increases the bass or low frequency response while simultaneously decreasing the treble or high frequency response. Likewise, rotating the knob clockwise increases the treble or high frequency response while simultaneously decreasing the bass or low frequency response. When the system EQ control is set at its notched or straight up position, the channel response is "flat" with no frequencies increased or decreased. For close microphone use, where low frequencies may become excessive, simply rotate the control clockwise until things sound better. For musical instruments or other sources where subtle or more significant boosting of both the high and low frequencies is desired, simply rotate the control until the sound achieves the desirable balance. For each new mix set-up start with this control in the notched position. 8
