Stereo Control Functions

MONO MIC / LINE CONTROL FUNCTIONS

CHANNNELS 1 - 4

J. LEVEL – Adjusts the volume level of the individual channel. Rotating the knob clockwise increases the respective channel’s contribution to the “Main Out” mix, while rotating it counterclockwise decreases the volume. Adjust this control after the Passport’s master output level volume has been set.

K. VIP (CHANNEL 1 ONLY) – The VIP or Vocal Input Priority control adjusts the level at which the volume of all other channels are automatically reduced in favor of the source attached to the Mic/Line Input 1. This unique feature permits a user to speak while other inputs (such as background music) continue at temporarily reduced levels. The VIP circuit is “pre-volume control” which means it is effective regardless of level control setting of channel one. Adjust this control while speaking into a microphone on channel 1, with other program material input through another channel. Depending on the duration and level of the signal being input to Mic/Line 1 and the position of the control, the VIP circuit will trigger a reduction in level of all the other channels. The original levels will be automatically restored when there is no signal present on channel 1. In typical use, the circuit will return normal levels in about 4 seconds. With the level set at a higher or a stronger signal, normal levels will be restored after approximately 6 seconds. The VIP circuit has an intentionally slow release time which prevents interruptions when a speaker pauses for thought or effect. Care should be taken to avoid the VIP triggering on sound from the main speakers. At high settings, the microphone may “hear” the main system speakers and trigger a reduction in level. When not using the VIP feature, be sure to turn the control completely counterclockwise.

L. EQ – Adjusts the amount of frequency increase or decrease in the channel. 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 tone controls are set at their notched or straight up position, the channel response is “flat” with no frequencies increased or decreased. To set the EQ, start with this control in the 12 o’clock (notched) position. Simply turn the control until things sound good!

M. REV/AUX – Adjusts the amount of signal sent to the Reverb processor, and to the Rev/Aux output jack. Reverb can be used to enhance the sound quality of any

performance where appropriate and desired. In the full left position there is no level sent to the reverb processor or Rev/Aux jack. Care should be taken to set the Reverb return master control to a middle position or above, before adjusting levels from the individual channels. When the reverb/auxiliary mix is set, overall levels of reverb can be adjusted at the master control.

Keep in mind that while Reverb or effects can enhance a musical performance or presentation. Too much reverb can make the same performance or presentation unintelligible or “muffled”. Keep your audience in mind when setting reverb levels.

N. PAN – The Pan control features a notched position indicator and adjusts the perceived “position” of the mono signal from the input within the stereo field created by the two speaker cabinets. Full Left or Right rotation of this control sends the signal to the that channel only, with no signal sent to the other. The center position sends the

same amount of signal to both speakers.

J. STEREO INPUT LEVEL – Adjusts the volume level of the stereo input channel. Rotating the knob clockwise increases the stereo input channel’s contribution to the “Main Out” mix, while rotating it counterclockwise decreases the volume. Adjust this control after the Passport’s master output level volume has been set.

L. EQ LOW – Adjusts the relative level of the low frequency content for the stereo channel. Rotating the knob counterclockwise decreases the bass or low fre- quency response. Likewise, rotating the knob clockwise increases the bass or low frequency response.

L. EQ HI – Adjusts the relative level of the high frequency content. Rotating the knob counterclockwise decreases the treble or high frequency response. Likewise, rotating the knob clockwise increases the treble or high frequency response. When the EQ controls are set at their notched or straight up position, the channel frequency response is “flat” with no frequencies increased or decreased.
