5.Installation

5.1 Rack mounting

Your iNUKE amplifier fits into a 19" rack and requires two rack units. Install into the rack using four attaching screws and washers for the front panel. Reinforce the back panel, especially if you will be taking the iNUKE on the road. Make sure enough cool air reaches the rack, especially when other rack equipment emanates a lot of heat. The iNUKE amplifiers circulate heat from the rear to the front vents to relieve heat inside the rack enclosure.

Fan speed adjusts automatically to assure safe operation. Never block ventilation openings. Should internal temperature reach extreme values, the unit will shut down automatically.

5.2 Connections

5.2.1 Audio inputs

Each channel input uses combo jacks that can accept both balanced XLR and

¼" TRS stereo connectors, as well as unbalanced ¼" TS connectors. To deploy XLR connectors for unbalanced signals, bridge pins 1 and 3; mono ¼" TS connectors do not require any alteration to carry unbalanced signals.

When working with balanced signals, please make sure to exclusively use balanced cables. One unbalanced cable in the signal chain can change a balanced signal into an unbalanced signal.

5.2.2 Outputs

Your iNUKE amplifier requires two twist-locking professional speaker connectors. These professional speaker connectors were developed specially for driving high-powered speakers. The connectors snap in securely, prevent electric shock, and ensure correct polarity.

Inside the professional speaker connector, the 1+ pin (see figure) carries signal from either one or both channels, and this pin therefore suits mono-bridged operation (use pins 1+ and 2+). The lower connector, the 2+ pin, carries signal from CH B only.

For connection of balanced and unbalanced plugs, ring and sleeve have to be bridged at the stereo plug.

◊Whenever possible, use thick and short speaker cables to minimize power loss. Never lay output cables near input cables.

5.2.3 Connecting to the mains

Always connect your iNUKE amplifier to the voltage specified on the rear of the device. Connecting the amp to an incorrect voltage can permanently damage your amp.

Before powering up the amplifier, double-check all connections and fully lower the gain setting.
