For mobile use, the amplifi er should also be secured using the 19” mounting elements on the rear panel. -
Page 14: Cooling
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. -
Page 15: Mode Selector
3.8 Mode Selector The switch on the rear panel changes the operating mode. Moving this switch will shutdown the amplifi er and restart it in the new operating mode. 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 amplifi... -
Page 16: Mono-Bridge Operation
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. The second channel processes the same input signal, but with reversed phase. The (single) load is connected between the two positive channel outputs using a suitable connected SPEAKON connector. -
Page 17: Controls
WARNING ! SPEAKON connectors marked with the lightning fl ashes indicate high vol- tages 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 qualifi ed personnel. To prevent electric shock, do not operate the amplifi... -
Page 18: Gain Selector
This switch on the rear of the VORTEX allows the maximum amplifi cation attainable to be set directly in the input stage. The VORTEX amplifi er has a 26 dB and 32 dB voltage gain setting along with a 1,4 V sensitivity setting. -
Page 19: Signal Leds
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. -
Page 20: Speaker Protect Limiter
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. -
Page 21: Mains Failure Detection
4.4.3 Mains Failure Detection Mains Failure Detection is always operative. When the mains supply is interrupted for about 2 mains cycles, the amplifi er 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... -

Page 23: E.u.i.2(Extended User Interface)
You can use the E.U.I.2 as a fi lter, remote control, signal processing device and more… Please contact your dealer/distributor or CAMCO to customise the E.U.I.2 according to your wishes. 5.2 CAI (CAMCO Audio Interface) CAI is a bus system, in which all signifi cant device functions can be monitored externally and remotely controlled using a master PC. -
Page 24: Cai Address Settings
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. Briefl y 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. -

Page 27: Problem: No Sound
Keep the VORTEX Volume Pots at least halfway up and try changing input sensitivity from 1,4 V to 32 dB or 26 dB with the Gain Selector on the rear. -
Page 28: Problem: Hiss
6.6 Problem: Hiss Unplug the amplifi er 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 fl oor low, operate the primary signal source at full level, without clipping. - Page 29 Output Power 1 kHz, THD ≤ 0,1 %, in mono-bridge mode 1 kHz, THD ≤ 0,1 %, both channels driven Duration limited by fuse / thermal protection for RL < 8 Ω in stereo mode or RL < 16 Ω in mono-bridge mode.
