C +48V indicators These indicators indicate the on/off status of the +48 phantom power of the corresponding channels. D HPF indicators These indicators indicate the on/off status of the high pass filter of the corresponding channels. E Level meters These meters indicate the corresponding channel output level in six steps. F Channel Select buttons These buttons enable you to select channels to edit. G [+48V] button This button turns the +48 phantom power of the selected channels on or off (See page 7.) The button indicator lights up when the +48V phantom power of the selected channels is turned on. • If you don't need phantom power, be sure to turn this button off. CAUTION • Before you turn phantom power on, make sure that no devices other than phantom-powered devices, such as a condenser microphone, are connected. Otherwise, you risk damaging the devices. • Do not connect or disconnect a device while phantom power is applied. Doing so can damage the connected device and/or the unit itself. • To protect your speaker system, leave the power amps (powered speakers) turned off when switching the phantom power on/off. We also recommend that you set all output level faders to the minimum position. Otherwise, high-volume output may damage your hearing or equipment.

NOTE: The PAD will be switched on or off internally when the gain is adjusted between -14 dB and -13 dB. Keep in mind that noise may be generated if there is a difference between the Hot and Cold output impedance of the external device connected to the INPUT connector when using phantom power. K [+48V MASTER] switch This switch turns the +48V phantom master power on or off. L [POWER] switch This switch turns the power to the AD8HR on or off. The gain and high pass filter settings are stored even after you turn off the power to the unit. 5
