output, and boasts a complete EQ adjustment and intuitive display.
This device is well suited for applications such as classrooms, small meeting rooms,
lecture halls, bars/pubs, etc.
1.2. Features
3 audio inputs: 1x 2CH analog (RCA), 1x 2CH analog (3.5mm), 1x PCM
digital/optical (TosLink).
Audio inputs switchable by pushbutton, IR remote, RS232 or Web.
Supports 2x50 Watts for 2CH audio @ 8Ω.
Supports 1x100 Watts for mono bridge mode function @ 4Ω. This is also
appropriate to support 70V speaker systems when connected to a MuxLab 70V
transformer such as the 500755-70V.
Device controllable via RS232, IR, TCP/IP.
Supports a web-based GUI via the Ethernet port.
Volume/Bass/Treble are controllable by pushbuttons, IR remote, RS232 or
Web.
Easy adjustments via a volume (level) rotary knob.
Audio Cascade output support.
