Quick Start
Required Equipment
• MAX98400A EV kit
• 8V to 28V, 5A DC power supply
• Audio source with volume control (e.g., CD player)
• Two speakers
Procedure—Filterless Evaluation (U1)
The EV kit is fully assembled and tested. Follow the
steps below to verify board operation. Caution: Do not
turn on the power supply until all connections are
completed.
1) Verify that all jumpers are in their default positions,
as shown in Table 1.
2) If not using the filtered evaluation side, remove the
shunt on SHDN_2 (disable).
3) Connect the first speaker across the SPKL1- and
SPKL1+ PCB binding posts.
4) Connect the second speaker across the SPKR1-
and SPKR1+ PCB binding posts.
5) Connect the positive terminal of the power supply
to the PVDD binding post and the power-supply
ground terminal to the PGND binding post.
6) Connect the left output terminal of the audio source
to the INL1 RCA phono jack.
7) Connect the right output terminal of the audio
source to the INR1 RCA phono jack.
8) Turn on the audio source at minimum volume.
9) Turn on the power supply.
10) Gradually increase the audio source volume until
audio is heard through the loud speakers.
Procedure—Filtered Evaluation (U2)
The EV kit is fully assembled and tested. Follow the

as shown in Table 2.
2) If not using the filterless evaluation side, remove the
shunt on SHDN_1 (disable).
3) Connect the first speaker across the FOUTL2- and
FOUTL2+ PCB binding posts.
4) Connect the second speaker across the FOUTR2-
and FOUTR2+ PCB binding posts.
5) Connect the positive terminal of the power supply
to the PVDD binding post and the power-supply
ground terminal to the PGND binding post.
6) Connect the left output terminal of the audio source
to the INL2 RCA phono jack.
7) Connect the right output terminal of the audio
source to the INR2 RCA phono jack.
