3.4
A
NALOG AUDIO INPUT
Connect analog inputs to either the RCA (single-ended) or the XLR (balanced) connectors. The amplifier must be
configured for analog input (see
).
If connecting more than one PWR-ICE amplifier to a single source channel (for example, if connecting a
subwoofer as well as a speaker to a preamplifier output), use a Y-splitter adapter or cable. Check the
specifications for your preamplifier to ensure that the minimum specified load impedance is less than 10
kΩ/(number of connected PWR-ICE125 amplifiers).
Connect only RCA or balanced (XLR) inputs. Do not connect both at the same time.
3.4.1
Input sensitivity jumpers
The input sensitivity of the analog inputs can be changed with jumpers on the DSP board. There are three
jumpers for each channel, and all jumpers for each channel must be set the same (i.e. all three open or all three
closed).
