Warning Notices

Location

Install the amplifier in a ventilated enclosure ( IP20 at least ), where it will not be directly exposed to high temperature or humidity.

Do not install the amplifier in a location that is exposed to direct rays of the sun, or near to hot appliances or radiators. Excessive heat can adversely affect the operation and internal components. Installation of the module in a damp or dusty environment may result in malfunction or accident.

Precautions regarding installation

Placing and using the amplifier for long periods on heat-generation sources will affect performances. Avoid placing the amplifier on heat-generating sources. Install this amplifier as far as possible from tuners and TV sets. An amplifier installed in close proximity to such equipment may cause noise or degradation of the picture.

Safety rules

PowerModII

CAUTION


DO NOT OPEN

!

This device must be powered exclusively by earth connected mains sockets in electrical networks compliant to the IEC 364 or similar rules.

Is absolutely necessary to verify this fundamental requirement of safety and, in case of doubt, require an accurate check by a qualified personal.

The constructor cannot be considered responsible for eventual damages caused to persons, things or data for the missing of accurate earth link.

Provide the installed unit with bipolar switch to unconnect both mains connection with at least 3mm of distance of the switch contacts.

Before powering this device verify that the module is supplied with the correct voltage rating.

Verify that your mains connection is capable to satisfy the power ratings of the device.

Do not spill water or other liquids into or on the unit.

Do not use this unit if the electrical power cord is frayed or broken.

Do not remove the cover. Removing the cover will expose you to potentially dangerous voltage.

No naked flame sources such like lighted candles should be placed on the module.

Contact the authorized center for ordinary and extraordinary maintenance.

Input mains and output power connection wirings must not to be accessible to the user.

Thermal constrains

PowerModII

CAUTION


DO NOT OPEN

!

This device must be correctly heatsinked for correct and reliable operation:

Two operating modes are feasible,

1) fan cooled operation

2) external heatsink operation

1) Thermal behaviour with provided fan cooler is warranted by design up to 45°C enviromental temperature with 6 dB power crest factor program operation, both channels driven on 4 ohms load.

2) Thermal behaviour with external heatsink is related to power operation level and load impedance.

For the above conditions (1), 150W of dissipated power is expected.

Considering that thermal protection is setted at 85°C on bottom aluminium plate, thermal resistance of the heatsink is derived from the following formula:

Rth(heatsink) = Maximum operating temperature – Maximum ambient temperature

Maximum dissipated power

For example, for a maximum ambient temperature of 45°C and a maximum operating temperature of the module of 80°C, for the 150W expected dissipated power is necessary an heatsink of 0.23°C/W

Rth(heatsink) = 80°C – 45°C = 0.23°C/W

150W

Proper heatsink planarity is strongly suggested to allow thermal transfer from the bottom plate to the heatsink, thermal compound is recommended also if not strongly necessary.

DGMDSPA installation

PowerModII

DGMDSPA installation consist in removing J3 and J4 to allow signal path to flow to DGMDSPA board.

Insert the DGMDSPA board on the only one spare simm socket on the main board of PowerMod module.

Take care that side holders are correctly closed and the polarization is respected.

The module is ready to work.

Note:

PowerModII up to Serial Number 717 need to be modified adding an electrolitic capacitor of 47uF/25 Vdc in position C63 see figure CONNECTING LAYOUT.

Without modification CH2 will suffer a turn off transient on loudspeaker output.

This is not dangerous but is noisy.

From Serial Number 718 the problem is production updated.
