Drivers were attached to it, while the preampliﬁ er is connected to it through copper bars.

The fan is managed by the ASC unit, permitting it to quickly reach the optimal temperature and stabilize it.

The air pulled in by the fan is discharged between the main board and aluminium bottom plate, then it goes out through

the input and power terminal sides of the ampliﬁ er.

Since this air isn’t extremely hot, due to small power dissipation, it helps to eliminate the possible stagnated hot air under

the main board mosfets.

The side ducts where both power supply and output power stage transistors are placed, including emitter resistors, are

coupled to it by ﬁ xing springs, and were purposefully sized to dissipate heat.

This system allows the air to go out through the ampliﬁ er top, thus avoiding the fact that, when the ampliﬁ er is embedded

into an into a custom installation, a closed area of hot stagnated air is generated underneath the ampliﬁ er which would

prevent the cooling system from pulling cool air in and would make the system inefﬁ cient.

Using ﬁ nned aluminium heatsinks, the ducts also employ a natural convection cooling system.

This way, if the forced cooling system loses efﬁ ciency, heat dissipation doesn’t fully fail and allows the ampliﬁ er to work

the same under normal listening conditions.

5 • INSTALLATION METHOD AND MAINTENANCE

a) Fixing plate and side handles

HV venti is equipped with a removable ﬁ xing plate, positioned beneath the bottom, and with two removable side handles

for its displacement.

Before installing the ﬁ xing plate, you have to remove it by loosening the four screws, two at each end; on the plate itself

you’ll ﬁ nd pre-drilled holes and slots to mount the ampliﬁ er to the installation site.

After this operation, take the ampliﬁ er by its handles and attach it on its pre-installed mounting plate. This operation is

easy thanks to the plate runners. Now secure the ampliﬁ er by fastening the four screws previously removed into the

mounting plate.

Once you have mounted the ampliﬁ er, in order to adjust the controls and connect the cables, you have to remove the two

ﬁ xing handles: beneath them you can make all the necessary adjustments and tighten the connecting cables.

Once handles are removed, access to the electronics is not possible in order to avoid any possible installation bits that

could fall inside of it.

When installation is completed, before placing the handles back, you have to mount them to the factory provided grilles,

which protect the displacement slot and cover cables.

The ideal installation of the HV venti is when the ampliﬁ er is partially embedded, so that the underneath mounting plate is

hidden and only the cosmetically appealing one are visible; this is the best choice both in terms of aesthetics and thermal

dissipation.

b) Glass panel

The glass panel is removable to enable you to change the setting of the Dual Power system (factory default is Hi Current),

or if you want to change Dual Bias conﬁ guration (factory default is Low). You have to remove the glass panel also if you

want to insert the optional crossover. Please be very careful while removing the glass panel. Also make sure no metallic

objects are left inside the ampliﬁ er before the glass is re-installed.

c) Maintenance

Since forced cooling systems draw dust, you have to pay special attention to maintenance.

For this reason the metallic grilles that protect the ﬁ ve fans are attached with a magnetic system and are easily

removable.

Underneath three of these metallic grilles, you will ﬁ nd a foam ﬁ lter, which stops the dust from the drawn air. Foam

ﬁ lters have to be periodically cleaned with soap and water; we recommend you clean them once every 6 months or less

depending on environmental conditions.

Once ﬁ lters are dried, they can be put back to their place. Do not use an external heat source to dry the foam ﬁ lters. Now

you can remount the grilles. You can ﬁ x them in four different ways according to which Audison logo side you want to be

visible.

The cooling ducts can be cleaned as well thanks to the two panels that are accessible beneath the HV venti ampliﬁ er. In

order to carry out this operation, you have to remove the ampliﬁ er.

This is a time consuming procedure so we recommend you to do it every time the ampliﬁ er has to be removed for

whatever reason.
