Mackie DL806 and DL1608 Reference Guide DL806 Rear Panel Power Switch Press the top of this rocker switch in to turn the mixer on and press the bottom of this switch to turn the mixer off. As a general guide, the mixer should be turned on first, before any external power amplifiers or powered speakers. As such, it should also be turned off last. This will reduce the possibility of any turn-on or turn-off thumps in the PA. Power LED This LED will illuminate green when the mixer is turned on. If it does not turn on, confirm that The Power Block and line cord are connected correctly (to each other, the mixer and the AC outlet), the local AC mains supply is active and that the power switch is on. Phantom Power Switch Press the top of this rocker switch in if any microphone requires phantom power. (Always check the position of this switch before connecting microphones.) This is a global switch that affects all mic channels' XLR jacks at once. Press the bottom of this switch in to turn the phantom power off. Most modern professional condenser mics require 48V phantom power which lets the mixer send low-current DC voltage to the mic's electronics through the same wires that carry audio. (Semi-pro condenser mics often have batteries to accomplish the same thing.) "Phantom" owes its name to an ability to be "unseen" by dynamic mics [Shure SM57 / SM58, for example], which do not need external power and are not affected by it, anyway. Never plug single-ended (unbalanced) or ribbon microphones into the mic input jacks when phantom power is on. Do not plug instrument outputs into the mic XLR input jacks with phantom power on unless you know for certain that it is safe to do. When phantom power is engaged, be sure that the master fader is down when connecting microphones to the mic inputs to prevent pops from getting through the PA. It is not a good idea to enable the phantom power unless it is actually needed. Line-level sources may be particularly unhappy when they are subjected to 48V phantom powering. Many musical instrument amps and keyboards with "direct outputs" fit this description. It takes approximately 15 seconds for the phantom power to shut off completely. Do not add or remove any inputs until the phantom power LED is completely off or mics could be ruined. 19

Power Switch

mixer off.

Power LED
This LED will illuminate green when the mixer is turned on

supply is active and that the power switch is on.
