INSTALLATION STEP 2
SELECTING INPUT MODES
REMOTE/LOCAL INPUTS
The
amplifier can be driven with either one, two, three or four separate “balanced audio” DIN inputs
(each DIN input contains an audio pair). your source unit has front and rear outputs, you can take
advantage of its fading capability by driving the
amplifier in 2 or
modes with two pairs of inputs.
When operated this way, the low pass subwoofer channel will operate in a non-fading mode-it derives its
signal from the Channel
inputs. included with the DaVinci amplifier is the Soundstream Limited
Edition BLT4, which drives two pairs of balanced audio lines. This is perfect for front rear fading capabilities,
or as a subwoofer level controller. Additional balanced line transmitters can be used to drive all of the
channels independently if desired. The “Remote/Local” inputs selector switches will be set based on the
number of inputs being used, and
the
mode in which the DaVinci amplifier is operating
Please
see the system diagrams on pages 18 21 for more details.
The stereo channels of the DaVinci amplifier have the ability to operate in either of the following modes:
with identical left and right stereo channels for maximum fidelity.
Bridged Mono for dedicated single channel operation; ideal for using the DaVinci in four or six-channel
operation. It is also used when large amounts of power are necessary for single speakers.
Any of the pairs of stereo channels of the DaVinci amplifier can be bridged onto a single speaker. For bridged
operation, please use the wiring
scheme
shown below. In bridged mono mode, only the right channel input is
active (i.e., use Channel 2 input for bridging Channels
Since the DaVinci is a full balanced input
amplifier and both the stereo left and right information is one balanced DIN plug, it may be necessary to drive
the right channel input of a bridged pair of channels with information from the left channel. The left and right
channel information can be swapped at the Balanced Line Transmitter by reversing the left and right channel
inputs from the head unit. This way, left channel audio will be fed to the right channel input of a bridged
pair.
However, an additional balanced line transmitter may be required to accomplish this. Please see the system
diagrams for more details.
