- CH1 - 6 are used for full range frequencies - CH7 - 8 are used for low frequencies.

Step 2: You can switch between channels to individually adjust parameters respectively.

Step 3: Repeat the process with each channel that you wish to adjust.

3.4 Audio Input Signal Selection

• While connected to a computer, select the appropriate audio input source in the Input Signal Selection and Connection Status area.

• The input selections are High Level, AUX, Phone and Player. The audio input signal can be selected from the audio input drop-down menu. The default source is high level.

• Each input source signal gain can be adjusted in the Mixer area. The adjustable range is 0-40.

12 1312 13

• Gain: The output volume for each channel is controlled by sliding the fader located below each channel label with a range of -59dB to 6dB. There is also a master volume of all output located in the middle far-left of the interface. The total master volume range is -39dB to 6dB.

• Mute: By selecting the mute button, you can turn the music signal for the selected channel ON/OFF

Figure 3.5.1

Note: The crossover and equalization parameters for each channel will vary depending on the specific channel and adjustments made in respect to the equipment used.

3.6 Output Channel Settings

In Figure 3.5.1, six output channels are being used. The most commonly used channel output settings are displayed. Users can customize the speaker type of each output channel. The output gain, delay, input type, mute and phase settings can all be adjusted for each seperate channel.

Figure 3.6.1

Users can customize the speaker type for each output channel by following the steps below:

Step 1: Click “Reset Output” button located on the right side of the Output Channel Configuration area. Select the “Emptied” option to set output types on all channels to NULL and return to the main interface.

• Phase: Select the phase button to alternate between positive phase (0°) and inverted (180°).

• Delay: The 3 possible units of delay are milliseconds (0.000~7.350ms), centimetres (0~254mm), and inches (0-100in)

• Output Type: The EDSP4-31BT processor output signal can be configured to any sound field point and speaker type. The system factory defaults is set to 4.1 full-range passive mode.

3.7 Output Delay Adjustments

3.8 Signal Equalizer Adjustments

The Output Delay Adjustments area is located left of the Output Channel Configuration area. To make adjustments to delay settings select the desired channel in the Output Channel Configuration area then input a value for the delay to be added to the corresponding speaker.

Changes to the equalizer settings can be made in the Crossover & Equalizer Adjustments area located above the Output Channel Configuration & Output Delay Adjustments areas, as shown below:

Adjustments: The EDSP4-31BT GUI allows the user to easily make changes. Use your cursor to drag the slider of the desired frequency band up or down. Whenever the parametric equalizer curve is available, each corresponding input parameter value will be adjusted in real time.

3.9 Signal Equalizer & Crossover Operation

3.9.1 Crossover Operation

Changes to the crossover frequency, type and slope settings can be made in the Crossover & Equalizer Adjustments area located above the Output Channel Configuration & Output Delay Adjustments areas, as shown below:

Channel Selection: You can choose to adjust the EQ of a specific channel by slecting a channel from the Output Channel Configuration area. The selected channel that is currently being edited will appear in a blue highlighted state.

Reset EQ: This operation will change the equalizer gains to 0db on all frequencies for the selected channel.

Crossover Type: click drop-down button to select from Linkwitz-Riley, Bessel and Butterworth for both High-pass and Low-pass filters.

Figure 3.9.1

Frequency: You can make adjustments to this setting via direct input value or by scrolling up and down with the mouse wheel to adjust low-cut or high-cut frequency. The adjustment range is 20Hz ~ 20KHz.

Reset Output: Selecting the Reset Output button will re-configure the output map of the selected channel. You can clear the mapping by selecting “Emptied“ or reset the mapping to default by choosing “Default“ from the pop-up dialog box that appears. If the output configuration is emptied, there will be no output signal to any channel speaker. This option is used to restore the output channels for a new system configuration.

Slope: You can set the slope of the frequency curve to 6dB/Oct, 12dB/Oct, 18dB/Oct or 24dB/Oct. You will not be able to make changes to the type setting if slope is set to 6dB/Oct. Instead, the type setting will automatically be set to NULL.

3.9.2 Equalizer Operation

Addition options for equalizer and crossover settings can be found in the Output Channel Configuration area located on the far right. These settings allow for quick and easy operation.
