2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any of the ventilation openings. Install in accordance with the manufacturers
instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus

The V190 external power supply has been developed to be used soley with the Midas Verona Series of audio mixing
consoles.
All backed up by the standard Midas Three Year Warranty.
Please take the time to complete and return the registration card and, to obtain the best results with a minimum of
effort, also read this operators manual.

The V190 series power supply unit is a two unit nineteen inch (2U 19”) rack mounted power supply for use with the Midas
Verona series of consoles only.
Before installing the power supply, please ensure that the correct mains supply voltage is selected on the rear of the supply.
The mains inlet is provided via a single IEC type socket. A mains cables is supplied with the unit. Never, under any
circumstances, should the power supply be operated without it’s safety earth connection.
The V190 series power supply should be installed into a 19” rackmount enclosure. If the power supplies are not in a
permanent installation, the rackmount enclosure construction should take into account the weight of the supply to prevent
damage to either the power supply or enclosure while in transit.
The V190 power supply has a forced air cooling channel flowing from back to front. To maintain adequate ventilation to the
unit, the cooling channel must not be blocked or hindered and one unit (1U) should be left free between the top of the
power supply and any other equipment or the rack. The rackmount enclosure should allow adequate airflow to both the
front and back panels of the power supply.
If using a number of power supplies, one unit (1U) space should be left free above each supply.
Some interference may be noticed when the power supply is situated in close proximity to the Verona console. Moving the
power supply away from the console will rectify this problem.
The power supply may only be serviced by authorised personnel. Refer all servicing to a qualified, approved Midas service
agent.
Depending upon where the power supply is installed, the interior of the unit will become, over time, dirty and will require
cleaning.
The power supply should also be serviced if it is dropped, exposed to rain or moisture, liquid has been spilled into the supply
or if the unit ceases to function normally.
The inside of the power supply contains potentially lethal voltages and is capable of providing high currents. To reduce
the possibility of electric shock, do not open the cover to the power supply. High voltages are still present in the
supply, even when isolated from the mains.

Connection
Operation
Before powering up the V190 power supply, connect either the front or rear power supply output to the power inlet socket
on the console.
The V190 power supply should be connected to the mains with the supplied IEC mains leads.
The V190 is a Linear power supply capable of operation where the nominal mains voltage is 100, 120,
220 or 240 VAC (50-60Hz). The correct mains supply voltage must be selected before applying mains
power to the unit.
To change the mains operation voltage, disconnect from the mains. Open the compartment above the
mains inlet connector with a flat bladed screw driver. Once open, you will see a drum with an operating
voltages printed on each face. Remove the drum, then turn the drum to the required voltage and return
o the holder. Press firmly and then close the compartment. Make sure that the correct voltage now
appears in the window of the compartment.
After connecting the V190 power supply to the console, switch on the power supply using the rocker switches on the front
panel. Power will be applied to the console.
The user may monitor the activity of each of the voltage rails using the LEDs on the front panel. Each LED will light to show
the rail is active. In addition, a Low Mains indicator is provided to alert the user to a mains undervoltage condition.
The V190 power supply provides:
+12 volts
18 volts
+ 48 volts
The power supply should only be connected to the console using the provided power connection cable. If, for any reason,
the power connection cable should become damaged, the cable should be serviced by an authorised Midas service agent
immediately or a Midas authorised replacement sought.
The V190 power supply is capable of providing high currents. A short-circuit on any of the voltage supply pins
of the power supply or connector will cause a high current to flow from the supply which could lead to damage both to the
supply and to connected equipment and also a risk of fire and severe burns to persons.
it t
The Midas V190 power supply MUST be earthed. The power supply should NEVER be used with the earth connection
removed. The mains inlet socket earth connection is a safety connection and should be connected to the mains earth
through the earth conductor in the provided mains lead.
To prevent the risk of fire, fuses should always be replaced with fuses of the same rating and type.
The internal operating temperature of the power supply could be sufficient to cause burns to persons. Do not open the
cover or attempt to remove or bypass the safety covers protecting the fan and cooling channel.

Using Multiple Power Supplies
Servicing and Maintenance
The number of power supplies shipped as standard with the Verona varies with the frame size as follows:
24 - 32 1 0
40 - 56 2 0
64 2 1
Where multiple supplies are present, these should be switched on at the same time so that excessive load is not applied to
any single supply.
The external power supply can be used on 24-56 channel frame sizes to add redundancy or replace the internal supplies.
Two external supplies would be required to replace the internal supplies of the 56 channel console and retain redundancy.
The external supply has a “daisy chain” facility (as shown below) allowing for a number of power supplies to be used
together adding redundancy to the system in the event of a power supply failing.

Under NO circumstances should the Venice series power supply be used with the Verona.
Only the MidasV190 Linear External Power Supply is approved for use with Verona consoles.
Both the Verona and the Midas V190 linear external power supply both contain potentially lethal voltages and should only
be serviced by authorised Midas service agents. In the event of malfunction, please refer servicing to qualified personnel.
Contact your Midas dealer for more information.
