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.
Intuitive LED indicators for input source, control and volume setting.
Power off memory.
Convection cooling, no fan needed.
Antistatic case design: providing good protection for long-term and stable
performance.

4.4 Audio Output Connection
4.4.1 Stereo output (default): 2x50 Watts @ 8Ω
Set the switch to STEREO to enable 2x50 Watts @ 8Ωfor stereo output mode. Connect
the amplifier and speaker normally as shown in the figure below:
Figure 4- 1 Stereo Output Connection
4.4.2 Mono output: 1x100 Watts @ 4Ω
Set the switch to MONO to enable to enable 1x100 Watts @ 4Ωfor mono output mode.
Connect the amplifier and speaker(s) as shown in the figure below:
Figure 4- 2 Mono Output Connection
Note: In mono mode the user can also connect a MuxLab 70V transformer such as the
500755-70V to support 70V daisy-chained speaker systems. This is useful for longer
speaker runs in a distributed speaker environment.
