Operation
7. Operation
Once all connections have been made and configuration
options selected, Danley DSA amplifiers are ready for
use. If an input signal above -60dB is present on any
input, the front panel Input and Standby indicators will
illuminate green to indicate normal amplifier operation.
Audio will be heard from any connected speakers.
Note: Danley DSA amplifiers will by default not wake from Standby
Mode unless an input signal is present, a network ‘ON’ command is
received, or an external standby switch (or 12V trigger) is operated.
Standby behaviour can be configured via the Power Management
menu of the Control Web App Settings Tab.
Amplifier outputs will mute if no input signal is present for 5
minutes, and the amplifier will switch automatically to Standby
Mode if no signal is present on any input for more than 15
minutes. Alternative standby and mute delay times can selected
via the
Settings Tab
. Amplifier cooling fan speed is temperature
controlled. The fan will switch off when the amplifier enters
standby mode.
