3.1 On/off Switch 3.2 Precautions NOTE: This switch does not isolate the appliance from mains. When mounting or connecting the amp always disconnect it from mains. It initiates start-up by activating the inrush current limiter. When the amp is connected to mains, only the line-filter and the input of the silicon controlled 3.3 Mounting rectifier (fused) are energised. Use four screws and washers when mounting the amplifier to the front rack rails. Rear support is also recommended, especially i

3.7 Input Signal Chaining The input signals to the XLR connectors can be hard-wired in parallel using a switch on the E.U.I. (See 3.6.2, Switch 1, 5.1, Extended User Interface and 5.1.1, Input Signal Parallel Switch). This serves as a replacement for an external short XLR female - XLR male cable for parallel linking the signal inputs. Switch S1 CAUTION: Linking channels together can cause damage to system components if for example two inputs are used with separate ‘LF’ and ‘HF’ feeds. If

4.1 Precautions improved noise characteristics. The implementation is comparatively simple: Only connect the VORTEX amplifier to a appropriate AC circuit and outlet, the volume potentiometers pass the relevant control information (quieter or according to the requirements indicated on the rating plate label. louder depending on the adjustment made to the potentiometers) to the microprocessor. The microprocessor then adjusts the power amp output using various strategies implemented in software

4.7 Fans The fans mounted in the VORTEX operate permanently, but as long as the temperature remains below 40 °C they run at their slowest speed and can hardly be heard. The highest detected temperature from either channel controls the speed of the fans: above 40 °C the speed is increased until it reaches its maximum value. 4.8 Filter Cleaning A removable filter system is provided on the air intakes to the cooling system. If the filter becomes clogged, the unit will not cool as efficiently as it
