Needs the chassis ground for reference, otherwise a current loop is formed via the signal ground. Use the balanced input to avoid hum and interference. 5. Power consumption there are three ways to determine the power/current consumption of the amplifier: first, the peak current draw at full output p...
Figure 5. Rear panel connectors do not use xlr and trs jacks on the same channel simultaneously for mixing or other purposes. Figure 6. Balanced line to connect an unbalanced source, tie pin 3 (ring on trs jack) down to the shield of the connector. If you leave one pin disconnected, you will lose 6 ...
Level attenuators are active, allowing you to set different levels for each channel. Never connect either output terminal to ground or in parallel. 3. Bridged mono to bridge the amplifier, depress the link switch (6) and phase reverse switch (5). Both channels are then driven by a single signal at e...
Figure 12. Front indicators 4. Indicators the two bottom green ”on” leds indicate that the output circuits are receiving the correct rail voltage. The ”-25 db” leds glow when the output signal is greater than -25db, 0db is referenced to full output power. These leds also act as signal present indica...
Thanks to a horizontal pressure chamber in front of it, (in a conventional tunnel design the end of the heat sink opposite to the fan invariably gets hotter than that directly in front of the fan). When cool air hits the geometric fins of the intercooler tm , turbulence is produced thereby enabling ...
