Input Control And Monitor Sub-Panel
JBL DrivePack^®

This sub-panel is used to configure the input section of the amplifier. The functionality of basic controls and metering found in the input control block are identical to similar controls and meters found in the Output Control block.

Clip Indicator

The clip indicator (above the Input Meter) indicates when either the analog or digital signal input level is exceeding limits.

Digital Input – Clip occurs if signal reaches 0 dBFS

Analog Input – Clip occurs at 7 dBu with +4 dBu input sensitivity and 23 dBu with 20 dBu input sensitivity.

Gray - Detects the input signal of the device is below clipping.
Red - Clip detection monitors input, DSP, and each amplifier output channel. The indicator color changes to Red when clipping THD at any point is detected.

Input Meter

Indicates the pre-input control fader signal level into the analog or digital inputs of the input module in dBFS from –60 dBFS to 0 dBFS. The meter also displays both RMS and Peak signals superimposed. The Input Gain Fader does not affect the level displayed on the Input Meter.

Input Gain Fader

This control allows the user to adjust the signal level into the amplifier module. The user can use the mouse to increase and decrease the gain by moving the gain slider control up or down or clicking on the up and down arrows of the gain control until the desired gain is attained. The user can also edit this parameter directly by clicking on the gain parameter and modifying the number with the keyboard then pressing "Enter" to activate the change. Adjustment range is –80 dB to 20 dB.

Input Gain Spinner Control

The Input Gain Spinner control allows precision incremental control in 0.5dB steps by clicking on the UP or Down tabs. The spinner control also allows a numerical gain value to be input directly into the text field.

Polarity Indicator/Control

Polarity Control – Toggle button. If needed the polarity can be reversed by clicking the polarity button.
Green - Positive Polarity indicator shows "Pol (+)" and is colored green when the polarity is set to positive.
Yellow - Negative Polarity indicator shows "Pol (-)" and is colored yellow when the polarity is set to negative.

Mute Indicator/Control

Mute Control – Toggle button. If needed the input can be muted and un-muted by clicking the Mute/Muted button.
Green; Not Muted – Indicator is Green and reads "Mute" when the input section is active (not muted).
Red; Muted – Indicator is Red and reads "Muted" when the input section is inactive (muted).

Input Sub-Panel

User can double-click on the INPUT button control to configure the input for the device. When the INPUT button control is double-clicked the user is presented with the DrivePack Source Routing control panel.

Input Compressor

The user can double-click on the COMP button control to configure input compression for the device. When the COMP button control is double-clicked the user is presented with the DrivePack Input Compression control panel.

Input Delay

The user can double-click on the DELAY button control to configure input delay. When the DELAY button control is double-clicked the user is presented with the Input Delay control panel.

Sub Filter

Double clicking the Sub Filter control button opens a graphic High Pass/LoPass filter control sub panel. The Sub Filter controls allow the user the fine tune the top-box-to-subwoofer crossover region and provides both a graphical interface and direct value entry. For more details click Sub Filter

Gain Reduction Meter

The Gain Reduction Meter indicates the level of reduction of the output of the input amplifier in dB, from –60 dB to 0 dB, in the event the factory set protection limiters go active. The protection limiters go active when the output signal exceeds normal range.

Ready Indicator

The Ready Indicator indicates that the input module is ready to process input signals.

Green – Indicates the self test has completed successfully and that the input module is ready for processing input signals.
Red – Indicates the self test is in progress and that the input module is not ready for processing input signals.

Temperature Indicator

The Temperature "LED" indicates the temperature of the input module.

Green – Device temperature is within defined normal operating conditions.
Yellow – Device temperature is above defined normal operating conditions and within the first stage of thermal limiting.
Red – Device temperature is in advanced stages of thermal limiting and within the thermal shutdown range. Action should be taken immediately to correct the situation.
