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.

◊ 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.
