V SA - UI- DP Us e r In t e rfa c e Ke y p a d
The VSA-UI-DP is the optional wall mount keypad used to control the system. Of
course the system can be controlled via the state-of-the-art web control using Smart
phones, tablets, or PCs, however, the UI gives the ability to control the system directly,
adds IR capabilities (extends IR as well as issuing programmed IR commands), and
adds a 2
nd
RS-232 port.
NOTE
The Audio Amp can drive loads equal to or greater than 8 Ω. Using
lower loads may cause over-current shutdown of the Audio amp, which
would require an All-Mute procedure to reset the amp. If you will be
using a single speaker connection for each side use 8 or 16 Ω speakers.
The amp can drive around 45 watts total into 8 Ω loads, which can be
very loud for a small room. Using 16 Ω speakers will cut the power
delivered by half.
To drive 2 speakers from each side, you need to connect two 16 Ω
speakers in parallel or two 8 Ω or 4Ω speakers in series as shown
below. Never connect two 8 Ω speakers in Parallel!
