3 INSTALLATION 3.1 Mains supply When mounting or connecting the amp always disconnect it from mains. Only connect the VORTEX amplifier to an appropriate AC circuit and outlet, according to the requirements indicated in the second line on the rating plate.

For mobile use, the amplifier should also be secured using the 19” mounting elements on the rear panel. P.12 USER MANUAL VORTEX 6, 4, 2.
3 INSTALLATION 3.4 Cooling Under normal operation of the power amp, overheating should never be a problem. The air is taken in from the front and out through the back. It is of course essential that while the power amp is running air is able to circulate around it freely. The efficiency of the cooling will depend on the immediate environment (e.g. an enclosed rack, direct sunlight) and on whether the front filter is clogged.
3 INSTALLATION 3.8 Mode Selector The switch on the rear panel changes the operating mode. Moving this switch will shutdown the amplifier and restart it in the new operating mode. 3.9.2 Stereo Operation Two fully independent amplifier channels (normal operating mode). VORTEX A (L) 3.9 Wiring 3.9.1 E.U.I. and XLR Connection XLR: Pin 1 = Ground (or lifted via 15 Ω resistor) Pin 2 = Hot (inphase) Pin 3 = Cold (out of phase) Always use symmetrical (balanced) shielded cable to connect the amplifier.
3 INSTALLATION mode is useful when, for example, 3 identical loudspeakers are to be operated with the same power. 3.9.4 Mono-Bridge Operation One-channel mono bridged operation. 3.9.5 SPEAKON Connection Both SPEAKON connectors are connected to channel A and channel B outputs.
3 INSTALLATION / 4 OPERATION WARNING ! SPEAKON connectors marked with the lightning flashes indicate high voltages that are potentially life threatening. Wiring to these terminals requires installation by an instructed person or the use of ready-made leads or cords. Custom wiring should only be carried out by qualified personnel. To prevent electric shock, do not operate the amplifier with any of the conductor portion of the speaker wire exposed.
4 OPERATION 4.1.2 Gain Selector This switch on the rear of the VORTEX allows the maximum amplification attainable to be set directly in the input stage. The VORTEX amplifier has a 26 dB and 32 dB voltage gain setting along with a 1,4 V sensitivity setting. 4.1.3 Gain and Input Sensitivity The table shows input sensitivity per channel for a given gain and load. It also shows the gain for the 1,4 V input sensitivity. Model VORTEX 200V VORTEX 6 VORTEX 4 VORTEX 2.6 P.17 USER MANUAL VORTEX 6, 4, 2.
4 OPERATION 4.2.2 Signal LEDs The green Signal LED is illuminated when the voltage level at the output reaches approx. 4 V; this corresponds to a power of approx. 4 W over a 4 Ohm resistor. 4.2.3 Clip LEDs (multifunctional) The colour of the bi-coloured (green/red) LED changes between red, green and yellow depending on the load and the signal modulation conditions. (Yellow is created by a mixture of red and green light).
4 OPERATION 4.3.4 Speaker Protect Limiter Whenever the SOA protection of the power amp switches back the current rail there could be a small clipping at the output; but the microprocessor is also triggered by this protection and will reduce the signal level immediately to minimise the effect. The user can decide either to use Speaker Protect or not. If you use this amp for low frequencies (bass / Sub bass) and you want to squeeze the absolute maximum out of it, Speaker Protect can be switched off.
4 OPERATION 4.4.3 Mains Failure Detection Mains Failure Detection is always operative. When the mains supply is interrupted for about 2 mains cycles, the amplifier will switch off. When the mains voltage returns to a normal value, a soft start occurs. 4.4.4 Fuse Protection The average mains current can peak temporarily, depending on the load impedance and type of signal, at values several times higher than the nominal value allowed by the fuse protection.
4 OPERATION 4.7 Filter Cleaning The air intake on the front of your VORTEX 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. For changing the filter, no tools are required: first, gently slide the whole plastic filter assembly a few millimetres to the left and lift it from the front panel.
5 OPTIONS 5.1 E.U.I.2 (Extended User Interface) CAUTION! Always switch off and unplug the VORTEX from mains, before making alterations to the E.U.I. card. The E.U.I. card contains the Rear XLR Panel as standard. Other input cards are available (See 5.1.1 What Are The Possibilities Using The E.U.I.2?). To remove the E.U.I.2 unscrew the two Phillips head screws at the left and right end of the XLR-Panel and carefully slide out the E.U.I.2. To refit the E.U.I.2, carefully insert it.
5 OPTIONS 5.2.2 CAI Address Settings The CAI address selection procedure will not affect the operation of the VORTEX but whilst this procedure is active, the volume cannot be adjusted by using the pots. Briefly press the Enter-Switch . This push button switch can be accessed through the 3 mm hole in the front panel between the On/Off switch and the LEDs. Only operate this switch with an insulated object. To see the address you can use the scale markings of the potentiometers.
5 OPTIONS P.24 5.2.3 CAI Status Indicator This green LED indicates the presence of communication between PC and the amp. USER MANUAL VORTEX 6, 4, 2.
6 TROUBLESHOOTING P.25 6.1 On LED Flashing Sequences When switching on the amp the On LEDs flash twice accompanied by a flash of Clip LEDs. This is normal for the ‘Start’ sequence of the VORTEX. When switching off the amp the On LEDs flash several times followed by a flash of Clip LEDs. This is normal for the ‘Shut Down’ sequence of the VORTEX. (It is the same as the loss of the mains voltage.
6 TROUBLESHOOTING 6.2 Problem: No Sound Indication: On LEDs not lit Clip LEDs not lit Check AC plug. Confirm that AC outlet works by plugging in another device. Indication: On LEDs lit Signal LED not lit Make sure the signal source is operating and try another cable. Check position of Volume Pots. Indication: On LEDs lit Signal LEDs responding to signal level Check the speaker wiring for breaks. Try another speaker and cable. Indication: On LED(s) sequence The amplifier is in protective muting.
6 TROUBLESHOOTING P.27 6.6 Problem: Hiss Unplug the amplifier input to check that the hiss is coming from the source or from a device upstream. Erratic or popping noises indicate an electronic fault in the offending unit. To keep the noise floor low, operate the primary signal source at full level, without clipping. Avoid boosting the signal further between the source and the amplifier. 6.7 Problem: Squeals and Feedback Microphone feedback must be eliminated by the mixer controls.
