POWER AMPLIFIER OUTPUT CONNECTORS

Power amp output connection for the two channels A (left) and B (right) is provided via professional SPEAKON connectors.

These offer an electrical and mechanical secure connection which complies to all security regulations. It also allows the use of high quality speaker cables with a diameter of 4 x 2.5 mm2. The EV accessory assortment includes recommended cables and connectors.

A plastic cover to prevent inadvertent erroneous connection protects the BRIDGED OUT connector. Remove the cover only when actually operating the power amplifier in Bridged-Mode.

WARNING:

The speaker output terminals are marked with a symbol “ ”, which signifies that these terminals present a shock hazard to the user.

BRIDGED MODE

With the BRIDGED-MODE switch being engaged, using the channel A input

for audio signal feed is mandatory, since input B provides no function. While

the amplifier of channel A operates as usual. Additionally, the audio signal is

internally inverted and routed to the amplifier of channel B. Both amps – A

and B – now work in push-pull operation to provide doubled output voltage at the BRIDGED-OUT connector.

The regular output voltage of each amplifier channel A + B is still present at the corresponding output connectors CHANNEL A and CHANNEL B. However, using these signals is not recommendable because of the aforementioned phase inversion. Operating the power amp in Bridged Mode with loads

of 2ohms connected is not allowable.

CAUTION: Operating the power amplifier in Bridged-Mode may result in extremely high voltages being present at the BRIDGED OUT connector. The connected loudspeaker systems have to be designed for handling such high voltages. Please carefully read the power handling specifications as stated in the documentation of the according loudspeaker system and make sure to check whether they are in compliance with the output capacity specifications of the power amplifier.

GROUND-LIFT SWITCH

The ground-lift switch allows eliminating noise loops. When operating the power amplifier in a 19“ rack-shelf system or cabinet together with other equipment, setting the switch to its GROUNDED position is recommended. When operating the power amplifier together with appliances with differing ground potentials, set the switch to its UNGROUNDED position

MAINS

Under normal circumstances, the mains fuse only blows in case of fault. Replacing the fuse is only permissible for authorized service personnel using a new fuse of the same type with identical amperage, voltage and blow characteristics. The high-performance mains cord supplied with your with applicable safety regulations, plus that its diameter corresponds to the

power amp’s power output capacity. Whenever possible make sure to use the supplied mains cord for connecting the power amp to the mains network. Using a different mains cord with a smaller diameter results in higher leakage, consequently reducing the amplifier’s maximum power output capacity.
