Introduction
The Model 207 eSports Console offers a
unique combination of analog and digital
audio resources specifically intended to
support eSports-related live event, entertain-
ment, and streaming broadcast applications.
The unit is housed in a compact, rugged
steel enclosure that’s intended for table-top
use. Its diminutive size also makes it ideal
for use in space-constrained locations. Blue
LED lights cast a distinctive “underglow”
from the bottom of the enclosure. The Model
207 supports Dante® audio-over-Ethernet
digital media technology with AES67 com-
patibility for integration into contemporary
applications. The unit is extremely simple
to deploy, is “pro” quality throughout, and
provides an intuitive user experience. The
Model 207’s audio quality is excellent, with
low distortion, low noise, and ample head-
room. Careful circuit design and rugged
components ensure long, reliable operation. Figure 1. Model 207 eSports Console front and
