6.0 E4 System Setup 6.1 Introduction POWER switch Rear This section provides instructions on setting up an installed E4 system. To set up an E4 system you need a PC running the FreeSpace® Installer™ software. RISK OF ELECTRICA L SHOCK DO NOT OPEN RISQUE DE CHOC ELECTRIQUE NE P AS OUVRI R ON POWER OFF 6.
6.0 E4 System Setup 6.3 System setup procedure 6.3.1 Output gain The first time you turn on an E4 system it loads its factory (default) configuration settings. These settings were stored in the E4 when it was manufactured. Once your PC is fully connected to the E4 system, you can use the Installer™ software to make changes to the factory configuration settings. The controls in the Output Gain control panel allow you to control the amplifier output of the E4 system. Page gain setting Max.
6.0 E4 System Setup 2. Set the minimum output gain. This sets the desired minimum volume within a zone. Play a source that will be used in the zone and adjust the volume slider to the desired minimum level. Raise the minimum gain stop up to the volume slider level. 3. Set the initial output gain. When the E4 system is switched from standby to operating mode, it loads its configuration (initial settings). Wherever the volume slider is set when you save the configuration becomes the initial gain setting.
6.0 E4 System Setup Programmer’s Note: If you are using the E4 system to drive speakers that are not Bose® products, choose the No EQ setting or one of the four high-pass filter settings at the end of the list. The No EQ setting helps protect the E4 against loudspeaker transformer saturation when non-Bose loudspeakers are connected to the E4 hardware. This setting acts as a band pass filter and allows energy between 80 Hz and 16 kHz to be sent to the amplifier section of the E4 electronics. 6.3.
6.0 E4 System Setup Input gain setup sequence Input gain meter – The input gain meter indicates the average input signal level of the hardware. The meter is divided into three color segments: 1. Set Opti-source® to Off. This allows you make the initial gain setting. 2. Select the source Type and determine if Mic Power +12V is needed. Set Mic Power to On if required. Leave it in the Off setting if you are using line inputs.
6.0 E4 System Setup 6.3.4 Source assign When the source appears in the ZONE Sources list, it is assigned to the current zone. Once a source is assigned to a zone, that source is no longer available in the System Sources list and appears grayed out. In the Source Assign control, you can choose which system sources will be available in each zone. The Source Assign control panel lists all system sources on the left and zone sources on the right.
6.0 E4 System Setup To set up paging in a zone 6.3.6 Page setup In order to use paging in a zone, first you must assign the PAGE source to the zone. Then select the appropriate settings in the Page Setup (page 50) control pane. The Page Setup control panel is used to set up the MIC/PAGE/ LINE 4 input for paging. The page setup is available when “Mic/ Page” or “Line/Page” is selected for “Type” in the Input Gain control panel. Paging type Detection type Active page indicator Ducking parameters 6.3.
6.0 E4 System Setup Page setup with Opti-voice® off Setting up Multi-zone paging 1. Set Opti-voice to Off in the Page Setup control panel. This enables the Ducking Depth and Release Time controls. 1. Assign the PAGE source to all zones that will be paged. See “To set up paging in a zone” on page 50. 2. Set the Ducking Depth to the amount in dB that the music will be reduced to once a page is triggered. 3. Set the Release Time to the length of time (secs.
6.0 E4 System Setup Paging operation 6.3.7 Zone EQ When a page signal is triggered, the music signal is ramped down according to the ducking time. The ducking time is preset at 20 ms for Auto detection and 0 ms for PTT triggering. The music level is reduced by the ducking depth which can be adjusted using the ducking depth control. Ducking depth is adjustable from 0 to –40 dB.
6.0 E4 System Setup 6.3.8 Dynamic EQ • DO NOT USE AUTOTRANSFORMERS: DO NOT use an auto transformer on the speaker line to adjust the speaker volume. Dynamic EQ will not operate properly with this added component. The Dynamic EQ control panel provides an on/off control to enable/disable Dynamic Equalization in the current zone.
6.0 E4 System Setup IMPORTANT: Before you calibrate Auto Volume Auto Volume setup procedure Programmer’s Note: While the Auto Volume calibration is running, • Make sure that the system hardware installation is complete and that all components (sense microphones, speakers, and Auto Volume user interfaces) are properly connected. Remember that speakers must be directly wired to the ZONE OUT connectors on the E4 rear panel. ZONE 1 Sense E4 System Mic ZONE OUT 1 • DO NOT use the paging microphone.
6.0 E4 System Setup 5. 6. Click Continue. Your Auto Volume Tracking settings are confirmed. If the tracking settings are not correct, click the Cancel button, change the settings, and start the setup process again. 7. Click Continue. All sources assigned to the zone are listed in the window. You are asked to confirm that a source is connected and operating. If the source list is wrong, click the Cancel button, use the Source Assign control panel to correct the problem and start the process again.
6.0 E4 System Setup 8. Click Continue to begin the source calibration process. 9. The source calibration process takes about three minutes per source. For each source, the input gain is measured and optimized, and the source level is activated. When this is done, the software displays the following confirmation. 56 of 80 Click Continue to begin the Zone Microphone Calibration. This calibration is performed using a test signal at the maximum zone volume and takes about 5 minutes.
6.0 E4 System Setup Programmer’s Note: If this process fails, a dialog similar to the following will appear. Check the sensing microphone installation and make sure all sources are operating. Following a successful microphone calibration, the software automatically flashes the hardware to save the configuration. 10. At the end of a successful Auto Volume calibration, the software displays a list of controls that are disabled when Auto Volume is on. Click Finish to exit Auto Volume Setup.
6.0 E4 System Setup When to repeat the Auto Volume calibration You will need to repeat the Auto Volume process if: Band pass filter ZONE source input • You reset a calibrated zone. • You physically replaced source hardware. • You moved a sensing microphone. • You changed a speaker tap. Auto Volume Algorithm • The source hardware has an output control and you changed its setting after you calibrated Auto Volume. • You have flashed an existing file into a new hardware device in a new installation.
7.0 User Interface Operation 7.1 Enabling keypad operation Standard User Interface Example User interface keys for assigned sources are enabled only after flashing the hardware. Keys for any unassigned sources are automatically disabled after flashing the hardware. 7.
7.0 User Interface Operation 7.4 Auto Volume user interface operation Auto Volume User Interface Example The Auto Volume user interface provides source selection, volume up/down, and Auto Volume on/off controls. Auto Volume User Interface Select LINE 1 input source Volume up (2 dB steps) Select LINE 2 input source Volume down (2 dB steps) Select LINE 3 input source Auto Volume on/off • Press 1, 2, or 3 to select the audio source connected to the LINE 1, LINE 2, or LINE 3 input, respectively.
7.0 User Interface Operation 7.5 Multi-zone paging user interface operation Paging User Interface Example: • The PAGE source is assigned to ZONE OUT 1 and ZONE OUT 4. The Multi-zone paging user interface provides keys to select single paging zones, all paging zones and initiate a page. • In the Page Setup control pane for ZONE 1 and ZONE 4: Paging zones are not the same as output zones.
