Functional Description
The Audiobyte Hydra ZAP is a stand-alone power supply, designed
specifically to power the Audiobyte Hydra VOX and Hydra HUB devices.
It is comprised of three totally isolated supplies and a CAN communication
interface used for load device control. The provided voltages are:
•one 5V DC/2A supply used as digital power (filtered using supercapacitors);
•one 7V DC/0.5A supply used as clock power;
•two ±10.5V - ±20V DC/0.5A adjustable supplies used to power analog
stages.
The user can control the device using its touch-screen display. Also, the
Hydra ZAP can be remotely controlled by the means of an Android/iOS app.
Please search for the Audiobyte Hydra Remote app on Google Play/App Store.
When the mains cable is attached to the Hydra ZAP, the unit is, by default,
in stand-by. In this mode, the screen will have a low blacklight level and will display
a red Audiobyte logo. To exit stand-by mode, the user must press anywhere on
the screen.
On stand-by exit, the main screen is shown. This screen elements are:
•in the upper-right corner the user can find the stand-by button. Pressing this
button will check if any Audiobyte devices are connected and send a shut-down
request. While these devices are shutting down, the red Audiobyte logo is shown,
in full brightness. If no Audiobyte devices are connected to the Hydra ZAP or if
shut-down confirmation received, the ZAP disables all supply outputs and enters
stand-by;

•in the upper-left corner there is the menu button, represented by an
Audiobyte blue logo;
•in the center of the screen, the monitored supply’s status is shown:
o fixed 5V supply status:
•supercapacitors charging –capacity percentage shown;
•digital supply operational –output (supercaps) voltage shown
(supply can be on or off);
•supercapacitors discharging –capacity percentage shown;
•supercapacitors discharged –capacity percentage shown.
o negative adjustable supply output voltage level;
o positive adjustable supply output voltage level.
Note: If one of the supplies has a red background, the respective output is user
disabled. Go to the appropriate control screen and turn it on.
•on the bottom of the screen, the Audiobyte Hydra VOX/HUB connection
status is shown. If the load device is detected on the CAN interface, the
correspondent radio button is marked with a green dot, as depicted in the image
above.
The menu screen has the following options:
•About button –this will open the system information screen;
•Digital button –will open the supercapacitor-based supply and clock
supply control;
•Analog Monitor button –allows access to positive and negative analog
supplies current and voltage real-time monitor;
•Analog Adjust button –used to access the analog supplies adjustment
screen.

On the top-right of the Digital screen, the user can press the ON/OFF button
to enable/disable the supercapacitor-based 5V supply output and to control
supercapacitor charge/discharge state.
Depending on the charge state, pressing this button will behave as follows:
•Capacitors Charging (output supply is disabled):
o Short-press on Digital ON/OFF –determines the state of the output
supply when the charging is complete (state changes to Capacitors
Charged);
o Long-press(5s) on Digital ON –enables the capacitor discharging
mode;
•Capacitors Charged:
o Short-press on Digital ON/OFF –enables or disables the output
supply;
o Long-press(5s) on Digital ON –disables the output supply and
enables the capacitor discharging mode;
•Capacitors Discharging or Capacitors Discharged (output supply is
disabled):
o Short-press on Digital OFF –enables the capacitors charging mode.
The Reference ON/OFF button is used to enable/disable the supply used
for clocks.
Note: When the 5V supply is in Capacitors Charged mode and the Digital
button is set to ON, if an Audiobyte device (Hydra VOX/HUB) is connected
to the Hydra ZAP, the supply control is taken over by the ZAP and the user
cannot turn ON or OFF any of the supplies, individually. In this case, the
supplies can only be turned off by putting the Hydra ZAP in stand-by mode
from the home screen.

The Analog supplies monitor screen has two dials used for graphical
representation of negative and positive current draw and numerical values for
actual voltages and currents measured just before the output switches.
If the numerical values have a red background it means that the analog
supply is disabled.
Use the button on the bottom-left to go back to the menu screen.
O the Analog adjustment screen, use the top-right button to enable/disable
both the negative and the positive voltages. Individual control for these two
voltages is not possible.
Note: If an Audiobyte device (Hydra VOX/HUB) is connected to the Hydra
ZAP, the supply control is taken over by the ZAP and the user cannot turn
ON or OFF any of the supplies, individually. In this case, the supplies can
only be turned off by putting the Hydra ZAP in stand-by mode from the
home screen.

Pressing the -and +buttons allows the user to set a new target voltage for
the two supplies (actual voltage of the two rails does not change if Live is not
active).
If target voltage has been tuned, the Apply button becomes active. Press
the Apply button to set the target to both supply stages and store it as default
(outputs can be enabled or disabled).
Activate the Live mode so that the stage voltages follow the target voltage,
as it is tuned. Make sure that analog outputs are enabled in order to see the
changes on the load. Press apply to store the tuned value as default.
Press the button on the top-left to return to the menu screen. If voltage is
tuned and Apply is not pressed, when exiting the screen, all adjustments are
cancelled and the previous voltage level is applied.
The Hydra ZAP can be remotely controlled using a dedicated Android/iOS
app. Please search for the Audiobyte Hydra Remote app on Google Play or App
Store. Installing this app will give you the possibility to control the Audiobyte Hydra
VOX and Hydra HUB devices as well.
If app has connected successfully to the Hydra ZAP, the app version can be
seen in the BT App Ver field of the system information screen.
Firmware Update
Update of the control firmware is done via the remote-control app. When a
new firmware version is available, the user is informed by the app, when the Hydra
ZAP is in stand-by.
