This model is designed to cover loop areas up to square areas of 250 square metres, or rectangular areas of over 400 square metres, depending on loop-aspect ratio.
The ILD300 is built in a half rack-width case. On the rear it has a single balanced microphone input using an XLR connector, with +15V phantom power available. A balanced line input is provided using a 6.35mm 3-pole jack socket, and an input / output using a 6.35mm three-pole jack for recording, slave and insert purposes. A mini-DIN connector provides an ancillary DC outlet, +/- 15V DC, for powering accessories such as Ampetronic’s pre-amplifiers, See Ampetronic Adapters and Pre-amplifiers. A preset control sets metal-loss correction. The IEC power inlet has an associated fuse, the loop output uses a detachable connector.
The front has recessed preset controls for sensitivity of the microphone and line inputs, drive current. Two four-LED displays indicate compression and loop current. LEDs indicate overload, over heat and loop error conditions. A 3.5mm stereo jack socket provides access to the actual audio signal in the loop for use with headphones. The power switch has an associated LED. It may be used free-standing or mounted in a rack or on a wall using accessory brackets.
