Crown XLS DriveCore 2 Series Power Amplifiers

Get Started Stereo Mode This is the default mode the amplifier is set to from the factory. Filters are available in this mode and will be described in detail in the Crossover Filters section on page 9. 1. Connect Left/Right signal source to Channel 1 and Channel 2 using either the XLR, ¼ Inch, or RCA connectors. 2. Connect a speaker to each channel output using Speakon, Banana Plugs, or bare wire.
Bridge Mode BRIDGE mode delivers the power of both amp channels into a single load of 4Ω or greater. Before you get started ensure that you: 1. Connect signal source to Channel 1 only using either the XLR, ¼ Inch, or RCA connectors. 2. Connect the speaker as shown. a. If using the binding post outputs, connect the positive terminal of the speaker to the positive terminal of Channel 1 and the negative terminal of the speaker to the positive terminal of Channel 2. b. If using the Speakon output, connect the positive terminal of the speaker to Speakon pin 1+ and the negative terminal of the speaker to Speakon pin 2+, then plug the Speakon connector into Channel 1 output of the amplifier. Follow these quick steps to configure the amplifier for BRIDGE mode: 1. Hold the MENU/SEL button for 1 second until the LCD screen displays the MAIN MENU. 2. Highlight AMP MODE and press the MENU/SEL button to enter the AMP MODE menu. 3. Press the NEXT button until BRIDGE is highlighted. 4. Press the MENU/SEL button to select BRIDGE mode. 5. Now the LCD screen displays the MAIN MENU. You may continue to the CROSSOVER menu status screen which will now show that the amplifier is in BRIDGE mode.

Menu Navigation

Main Menu
Enter the MAIN MENU by holding the MENU/SEL button beneath the display for about a second. From the MAIN MENU one may navigate, using the PREVIOUS and NEXT buttons, to one of four other menus or select EXIT to return to the status screen where only three lines of text are displayed. Use the up arrow or down arrow to highlight the menu you wish to go to and press the MENU/SEL button to make your selection.

AMP MODE

The AMP MODE menu is used to select one of three amplifier modes available in your XLS amplifier. The factory default is set to STEREO mode. In STEREO mode, Channel 1 and Channel 2 both function as independent amplifiers. BRIDGE sets the outputs into a bridge configuration as described in the BRIDGE mode section. The INPUT-Y mode allows the user to drive fro m the two channels the same input signal This is convenient for setting up crossover filters for bi-amplified systems.

Crossover

The CROSSOVER menu will allow the selection of filter type and filter frequency for each amplifier output channel. If the amplifier is in STEREO or INPUT-Y mode, you will first be prompted to select which amplifier channel to set up (BRIDGE mode skips this step). When you enter the CROSSOVER menu, the amplifier mode will be displayed.

Bridge Mode
Once you have selected the channel or if you are in BRIDGE mode, the available filter types will be displayed. Scroll to select between LOW PASS, BAND PASS or HIGH PASS filters, or select NO CROSSOVER. If a filter has been selected, the next screen will display the filter type and cut-off frequency. In the case of the BAND PASS filter, both the low and high cut-off frequencies will be displayed. Once you have selected the cut-off frequency or frequencies, you will be taken back to the MAIN MENU.

Input Sensitivity
The INPUT SENSITIVITY feature enables the playback from sources with inherently low output levels to drive the amplifier to full power by selecting ".775 - HIGH." It is recommended that this remain set at the default NORMAL setting for all other audio sources to provide optimal system performance. The HIGH setting is often used with source devices that use RCA connections.

INPUT SENSITIVITY
1.4V - NORMAL
.775V - HIGH

Additional Features

System Menu
The following features may be accessed through the SYSTEM MENU. The SYSTEM MENU is the fourth selection on the MAIN MENU. Since only three selections are displayed, you must scroll down using the NEXT button until SYSTEM is displayed and highlighted.

Display Sleep

The user may configure the amplifier to allow the display to go into a sleep mode after a pre-determined idle time. This feature can be useful in applications where it is desirable to minimize the light from the amplifier.

This feature may be accessed via SYSTEM > DISPLAY SLEEP. Within the DISPLAY SLEEP menu, the user has the option to set the sleep mode to off or to choose a delay time of 30 seconds, 1 minute, 2 minutes or 5 minutes. If no menu buttons are pushed and the time period elapses, the display will turn off. It can be awakened by touching any menu button.

LED Lighting Options

LED lighting Options can be accessed via SYSTEM > LIGHTING. Inside the LIGHTING menu, the user can toggle the on and off of blue panel lights as well as the green signal level indicators.
Note: The thermal and clip indicators cannot be disabled.

Security

A security feature allows the user to lock the menu buttons so that the settings are not disturbed once they have been set up. To enable the security feature, go to SYSTEM > SECURITY and press NEXT to toggle the display to ENABLE. Press MENU/SEL to return to the SYSTEM MENU. Once enabled, the user can lock-out the menu buttons by simultaneously pressing the PREVIOUS and NEXT buttons. The menu will remain locked, even through a power cycle, until the PREVIOUS and NEXT buttons are pressed again.

System Information

For the audio geeks that just can't get enough data, we have provided a window to access your amplifier's system information. SYSTEM > INFORMATION will reveal a list of information including the model number, internal temperatures and voltages, firmware release number, etc.

Reset Factory Defaults 
There may come a time when you just want to reset the entire system and start your setup from ground zero.If you are sure that you want to do this, 

WARNING: If you reset your amplifier, all settings will revert to the factory preset values and you will lose all configurations you may have entered for amplifier modes, filter frequencies, input sensitivity and system settings.
