Output Connections - VTC Pro Audio V64 Manuel De L'utilisateur

16. Fan Filter Maintenance
The V64 is factory equipped with fan filters mounted on the air-intake grills located on the amplifier's front panel.
Regular cleaning of these filters will increase the amplifier's long term reliability. The filters should be removed and
washed at the first sign of visible clogging. This will typically occur every four to six weeks depending on use and
environment. Replacement filters are inexpensive and can be ordered through VTC Pro Audio dealers. The foam
filters should be removed if a regular inspection schedule is not going to be followed. The amplifier can operate
without the filters in place, but the amplifier should be cleaned internally by a qualified service technician when dust
is visible on the heatsink fins.

Output Connections

The V64 uses Neutrik four contact Speakon™ connectors for output speaker connections. There are two Speakon™
connectors, one for each channel output. All connectors are connected to the amplifier's outputs whether the
amplifier is in stereo or mono modes. Connection configurations are labeled on the back panel.

Note: In an unusually dusty location, without regular filter inspections, removing the
foam filter can extend the operating time before thermal shutdown could occur. At
that time, the internal heatsinks should be cleaned thoroughly.
