3.5 TAS6424MS EVM Start Up
This section describes the TAS6424MS start-up procedure. Have the equipment and accessories listed on the
first page of this document available.
3.5.1 TAS6424MS EVM Setup
Hardware and software connections:
• Desk top or laptop PC running Windows 7. Open PPC3 GUI.
• Connect 14.4 VDC PSU to TAS6424MS EVM
• Connect speakers or resistive loads to TAS6424MS EVM
• Connect USB micro cable from PC to the EVM
• Set the switches (SPDIF, STANDBY, MUTE) to up positions
• Turn on the PSU
• Audio source: This can be a DVD player with optical SPDIF cable or Windows Media Player from PC
• At this point, 3.3 V LED, USB-LOCK LED and SPDIF-LOCK LED (if optical SPDIF is used) are on.
• If the SPDIF LED is not on, the default I2S input is the USB audio source.
• On the PPC3 window, launch TAS6424 EVM application
• The audio can be streamed now to the speakers. Go to the GUI and click on “Device Monitor & Control” box.
Click on play button located on the top right of the window.
• The following sections describe in detail the register settings of TAS6424MS.

3.5.2 TAS6424MS Settings on Device Monitor and Control Window
The TAS6424 Register Map window is for reference. Most of the register settings are done on the Device
Monitor and Control window
Click on “CONNECT” button on the bottom left corner of the TAS6424 EVM application window, see Figure 3-9.
The LED next to the TAS6424 EVM changes from gray to green and the “CONNECT” button changes to
“DISCONNECT” button.
Click on the TAS6424 Device Monitor and Control box. The following window is displayed.
Figure 3-9. Device Monitor and Control Window
This window has 6 major sections: Global Control Section, Channel Control Section, Miscellaneous Control
Section, Faults and Warnings Section, AC Load Diagnostics Section and DC Load Diagnostics Section.
3.5.2.1 Global Control Section
The Hi-Z, Mute and Unmute buttons with the gray background controls all 4 channels at the same time. When
Hi-Z is selected, all 4 channels are put in Hi-Z. The display for each channel in the channel control section will
reflect these buttons selections.
The Mute Pin button is the GPIO pin controlling the mute function of the device.
The Standby button is the GPIO pin controlling the standby function of the device.
The Reset button is software reset. This will put the device back in default settings.

3.5.2.2 Channel Control Section
Each channel has the same setting selections: Hi-Z, Mute, Play, Volume, Line-out mode and Speaker mode.
The drop down menu allows user to select either Hi-Z, Mute or Play state of each channel.
The volume slide controls the digital gain of each channel.
The default setting for each channel is speaker mode. If line-out is used, select Line Output button.
Figure 3-11. Channel Control Section
3.5.2.3 Miscellaneous Control Section
There are miscellaneous settings that are available on the GUI for easy access.
OSR is oversampling bit. For lower idle noise 64X OSR is set as default. For wider bandwidth, 128X OSR can be
used. 64X OSR is recommended.
TAS6424MS supports parallel Bridge-Tied Load. Channels 1 and 2 can be one PBTL channel and channels 3
and 4 can be the other. Before setting a set of channels to PBTL mode, connect the (+) terminals as PBTL
channel (+) and the (-) terminals as PBTL channel (-). Then connect the speaker (+) to the PBTL channel (+)
and connect the speaker (-) to the PBTL channel (-).
The over-current has two levels. The lower level is 1. The default is level 2. When running at lower output
current, OC level can be set to level1.
I2S and TDM are automatically detected. Use the pull down menu from “Input Format” box to manually select the
audio format. If sampling frequency is greater than 48 kHz, select 96 kHz from the “Input FS” pull down.
Over-temperature warning can be programmable, use the pull down menu to choose the OTW temperature. The
default setting is 120°C.
The output switching frequency (FSW) or Pulse Width Modulation frequency (PWM) is set at 2.1 MHz. The pulldown menu on the PWM FRQ box is used to choose a different FSW. LC value should be adjusted when FSW is
changed.
The offset phase for each channel is set at 45 degrees. This helps lower the ripple current on the power supply
as not all the channels switch at the same time. To choose a different phase offset, use the pull-down menu on
the “Phase” box.
There are four gain settings in TAS6424MS: low, normal, high and maximum. The default setting is high.
However, the recommended setting is normal for lower noise performance for driving speakers at
14.4 VDC. The gain setting is selectable via the drop down menu in the ”Gain” box.
The volume slew rate is measured with sampling frequency. The default setting is 1 period of sampling
frequency (FSYNC or FS). This rate is selectable from 1 to 8 sampling periods with the drop down menu under
“Vol Rate” box.

3.5.2.5 AC Load Diagnostics Section
AC load diagnostics report speaker impedance and phase. The diagnostics can be performed with one or all four
channels.
Select the correct output impedance and click start. Follow the pop up instructions to complete the load
diagnostics run.
Note
Make sure to set the digital input to 0 dBFS (100% full-scale). If the sine wave is provided from the
USB audio, turn the audio media volume and PC sound card volume to maximum.
Click on the “flip” icon located on the top right of the AC load diagnostics box to see the results.
Figure 3-14. AC Load Diagnostics Section
3.5.2.6 DC Load Diagnostics Section
The DC load diagnostics report if a channel is short to power, short to ground, short to load or open.
Select the impedance of the load from 0.5 to 5 Ω. Click start and then click the “flip” on the top right of the box to
view results.
If a channel is selected as a line-out, click on “LO ENA LD” to enable line-out load diagnostics.
“Retry” box is used when DC load diagnostics are run more than one time.
DC load diagnostics can be aborted by click on the “Abort LD” box.
