Communication
The sub menus accessible in the Communication menu are:
Comm Address
The Communication Address setting identifies the DPA-1’s to the PC interface or other Lyngdorf prod-
ucts. In master mode the DPA-1 setting is normally 1, and the addresses 2-99 can be used for individual
slave pre-amplifiers, but nothing is restricted. The PC software must know the address of the DPA-1 in
order to communicate with it.
Comm Speed
The Communication Speed setting is the RS232 Link interface speed. The default setting is 57600 baud.
With different PC’s and different lengths of cables the settings can be changed to 9600 or 115200 baud.
If a multi-amplifier set-up is installed with Master/Slave communication, a smaller delay can be observed
when using higher speeds.
Home Theater
If you are using a set-up with a Home Theatre Processor, where your Lyngdorf product is used to power
and calibrate the front left and right speakers, this feature will bypass the volume control. Connect your
HTP to the Analog Input 1 and activate the feature. Choosing Analog Input 1 will result in the amplifier
turning itself into a dedicated power amplifier with fixed and full gain.
(NOTE: do NOT test this feature with a CD signal running on the Analog input 1!)
When selecting other inputs the amplifier returns to the Default Volume
Master/Slave
As default a DPA-1 is set as a Slave. If set as a Master the DPA-1 will control the connected applicable
equipment, e.g. when adjusting the volume control and when switching on and off.
If updating firmware the DPA-1 must be set in Slave mode in order to communicate with the PC.
Digital Out
It is possible to select if the Digital Output should be the same channel as Main or the same as Line Out.
The Digital Out will have different functions, depending of the setup for Main Out, Line Out and cross-
over.
