5.5 Power management
It is possible to implement a power saving strategy to reduce power consumption and heat
build-up. By factory default, the power management feature is not active. Pressing and
holding the Preset Select button for at least 3 seconds will toggle the power management.
When active (Cyan Status LED), the Venu 208i will enter a low power operating mode after 15
minutes of no input signal (input level below -45 dBu). The DSP board will send a signal to the
amplifier module turning o the output stages and enabling standby mode (Blue LED).
On detection of an input signal (input level above -45 dBu), the DSP board will automatically
re-engage the amplifier module and exit standby mode.

5.7.1 Network troubleshooting
The Venu 208i cannot be discovered by Armonía Plus when it is set with a dierent subnet
than the network card to which it’s connected. In this case, after you have clicked on
Discovery, Armonía Plus will report that a connected device has an incompatible IP address.
Hovering the mouse pointer above the alert message displayed at the bottom of the Match
window will show the current device IP address. In order to discover the Venu 208i you will
need to adjust the settings of the PC network card to be compatible with those of the product
being connected to:
Go to Network Connection following this path: Control Panel \ Network and Internet \
Network Connections
Right click on the network card you are using and click on Properties. In the Networking tab,
find the item Internet Protocol Version 4 (TCP/IPv4), select it and click on Properties. This will
allow you to set a static IP address for the PC in the same range as the Venu 208i.
Figure 5.8: IP address warning
In Armonía Plus, re-enable the network card with the new IP settings in the Communication
Manager and follow the connection steps in Section 5.6. Once added to the workspace, you
can change its IP configuration as outlined in Section 5.7, then re-establish the PC network
card with the previous settings.

5.9 Internal signal path polarity
In order to increase the power’s supply energy storage eciency, signals coming from
channel pairs 1-2 are polarity reversed, one with respect to the other within the pair, when
entering the amplifier. This ensures a symmetrical use of the voltage rails: if, for example,
both channels’ 1 and 2 input signals are going through a peak at the same time, channel 1’s
energy will come from the positive voltage rails while channel 2, whose polarity is reversed
with respect to channel 1, will be fed energy from the negative voltage rails. In this manner,
the power supply will work symmetrically, with one channel catered by the positive rails and
the other by the symmetrical negative rails. Channel 2’s signal will be polarity reversed once
more to ensure that both channels output with the same polarity as their corresponding
input signals.
For this reason it is very important not to invert the polarity of either channels before feeding
them to the module. A double polarity inversion (the first by the user inserting the input signal
and the other by the amplifier’s internal circuitry) results in no inversion at all. If this were the
case, both channels would be weighing on only one side (positive or negative) of the power
supply’s voltage rails. This would result in an inecient use of the power supply’s energy.
Figure 5.10: Internal signal path polarity with example input signal.
Both channels 1 and 2 are fed with the same sine signal.
