Configuration

5.4.1 Input Setup

Open the configuration Dashboard and select the 

Input Tab

The Input Tab is shown in 

Diagram 5b.

•   To edit default input names simply select and type in the 

Input Name field.  

•   Define a mono or stereo input by selecting the appropriate 

option. Defining a stereo input will reduce the total number 
of discrete inputs available.

•   Select an input sensitivity option from the drop-down 

menu: +14dB, +4dB, -10dB and ‘microphone’ options 
are available. Generally, the +14dB or +4dB options are 
appropriate for ‘professional audio’ source hardware 
with balanced outputs, while the -10dB option is more 
appropriate for ‘consumer audio’ source hardware with 
unbalanced outputs. The ‘microphone’ option provides the 
significantly greater sensitivity required for microphones. 

Note:: Only dynamic microphones are suitable for connection. 
Phantom power for condenser microphones is not provided.  

•   If necessary, adjust the input gain using the slider or up/

down icons. Gain adjustment is intended to be used for fine 
output level adjustment following initial use.

5.4.2 Zone Setup & Routing

Open the configuration Dashboard and select the 

Zone Tab

The Zone Tab is shown in 

Diagram 5c.

•   Select the zone to be configured. The number of zones 

available and their channel format (stereo or mono) will 
depend on the amplifier model, input setup and output 
mode (Lo-Z or Hi-Z). For example, a two output amplifier 
can have the following zone configurations:

 

• 1 x stereo Lo-Z zone

 

• 2 x mono Lo-Z zones

 

• 1 x mono Hi-Z zone

•   A four output amplifier can have the following zones 

configured:

 

• 2 x stereo Lo-Z zones

 

• 4 x mono Lo-Z zones

 

• 2 x mono Hi-Z zone

 

• 1 x mono Hi-Z zone + 1 x stereo Lo-Z zone

 

• 1 x mono Hi-Z zone + 2 x mono Lo-Z zones

Note: When configured in Hi-Z mode Danley DSA amplifiers operate 
in ‘bridged’ mode where the output of two channels is combined. 
This means that the number of output channels available in Hi-Z 
mode is half that available in Lo-Z mode .

Note: Mono signals might be mono at source, created though 
combining the left and right channels of a stereo signal (summed 
mono) or treating the left and right channels of a stereo signal 
independently (split mono).

•  Name zones by typing in the Zone Name field.

•   Adjust the zone volume if required by using the slider.

•   Define a mono or stereo zone by selecting the appropriate 

option. Defining a stereo zone will reduce the total number 
of further zones available.

•   Specify an input for the zone by selecting from the drop-

down menu. Selecting a stereo input for a mono zone will 
automatically sum the stereo channels to mono.
