9.6 Locking

The locking mechanism allows to lock macro property values
based on the functional sub section and on the channel base of the
device; the lockable sub sections are:
f Input routing:
f Mono mix
f Input Section:
f Equalizer
f Output Section:
f Equalizer
f RMS Limiter
f Peak Limiter
f Damping Control
Every channel subsection is independently lockable.

9.7 On/Off

The on/off function is available when an external voltage is
supplied. Please refer to Section 9.3

9.8 Preset Management

The DSP allows to manage up to 4 presets per module and its
associated channel pair. Each preset contains information on the
following:
f Input routing
f Input Section
f Output Section
f Properties locking
The preset is handled by the client as a file with the .preset
extension.
These presets can be selected via a preset selection button
on the rear panel of the amp. There is one button for each DSP
module. The manual preset selection function is disabled if the
amplifier is remotely controlled by any client.
Amplifiers in the M Series are shipped with 4 default factory
presets: positions one and two store a 2 in / 2 out routing preset
each with an input delay of 170 ms. Positions three and four store
a 1 in / 2 out preset with 340 ms input delay each.

WARNING! Selecting a preset with a rear button or via
remote control will interrupt the audio stream
for some seconds.
WARNING! Store the modified preset before turning the unit
off or all changes will be lost.
NOTE: Selecting presets with the rear button is enabled only
if remote control is NOT active.

10 Remote control

The M Series HDSP+ETH boards allow full amplifier remote
control with Powersoft's software client Armonía Pro Audio Suite.
Other third party clients are also available.
Armonía Pro Audio Suite is a software environment entirely
developed in-house by Powersoft featuring full end user remote
control of Powersoft's amplifiers and audio signal processing. The
intuitive interface provides reliable information and real time
control of all DSP functions. Refer to the Armonía manual for
installation and configuration of the client software.
10.1

Networking

M Series HDSP+ETH amplifiers come with one rear RJ45 port
for remote device communication, using the IP layer and the UDP
protocol. Factory default settings are DHCP/AutoIP, but a fixed IP
policy can also be adopted.

10.1.1 Discovery device

In order to start remote
operation on the device
connected to your network,
it must be discovered and
imported into the Armonía
workspace.
It may happen that a static
IP in a different subnet with
respect to Armonía has been
assigned to your M Series amplifier (i.e. 10.0.x.y versus 169.254.x.y):
if this is the case Armonía does not recognize the amplifier. You
have to reset the IP configuration of your M Series amplifier: see
Annex 1 for the right procedure.

10.1.2 DHCP

When the data cable is connected the amplifier begins DHCP
handshaking. If a DHCP server is present on the network, the unit
is ready to be remotely controlled.
