i-SERIES 3 INSTALLATION ADVANCED AMPLIFIERS 3. Installation 3.1 Mains Supply When mounting or connecting the amp always disconnect it from mains. Only connect the iD4 amplifier to an appropriate AC circuit and outlet, according to the requirements indicated in the second line on the rating plate.
i-SERIES 7,50 mm 3.3 Mounting Use four screws and washers when mounting the amplifier to the front rack rails. For mobile use, the amplifier should also be secured using the 19” mounting elements on the rear panel. 88,10 mm 10,50 mm Note that continous high power draw at low load impedance (equal or less than approx. 2,7 Ω) can drive the amplifier into thermal limitation.

The pin configuration of the SPEAKON connectors is as follows: Always use symmetrical (balanced) shielded cable to connect the amplifier. 3.5.
i-SERIES 3 INSTALLATION ADVANCED AMPLIFIERS 3.7.2 Dual Channel Operation Two fully independent amplifier channels (“Stereo” – normal operating mode). iD4 In 1 In 2 Zmin = 2 Ω for Dual Channel operation 3.7.3 Mono Bridge Operation One-channel mono bridged operation. iD4 In 1 180° In 2 Zmin = 4 Ω for Mono Bridge operation In this mode the channel 2 amplifier stage processes the identical input signal than channel 1, but with reversed phase. The channel 2 input signal is not used / ignored.

i-SERIES 4 OPERATION ADVANCED AMPLIFIERS 4.4 Power Amp Protection Systems 4.4.1 Clip Limiter / Underimpedance Limiter The DSP section of the iD4 offers various limiter and compressor settings, both on the signal inputs and on the signal outputs. Those limiters and compressors can be adjusted and even switched off completely if desired. Disabling the limters is done by setting the thresholds to their highest values. But in case the amplifier is driven into hardware clip (i. e.
i-SERIES 4 OPERATION ADVANCED AMPLIFIERS P.17 4.5.5 Fuse Protection When driving the iD4 at very high output levels over a longer period of time (i.e. several seconds and minutes) the average mains current draw can become very high. In such situations, the FuseProtect limiter will reduce the output signal in order to prevent the external mains breaker from tripping.
i-SERIES 4 OPERATION ADVANCED AMPLIFIERS 4.8 Filter Cleaning The air intake on the front of your iD4 amplifier is fitted with a removable filter system. If the filter becomes clogged, the unit will not cool as efficiently as it should and may result in reduced output levels. iD4 Filter Assembly Foam filter Front frame Screw ! WARNING! Turn off and disconnect the amplifier from the mains before removing the front frame.
i-SERIES 5 TROUBLESHOOTING ADVANCED AMPLIFIERS 5. Troubleshooting 5.1 Problem: No reaction when switching the amplifier on If nothing happens when switching the amplifier on (i.e. the display stays totally dark, no message inside the display), please check following points: Check mains cable and plug Confirm that the AC outlet works by plugging in any other device 5.
