1. SPEAKER OUTPUT TERMINAL STRIP<br />
Connect up to five individual speakers to this strip.<br />
Impedances for 100V operation are shown below. Connect speakers whose combined impedance is equal to<br />
or higher than the rated output impedance, as shown below.<br />
2. ANTENNA CONNECTOR (OPTIONAL)<br />
This terminal is used to connect the antenna, when used with the optional <strong>PAM</strong>-T AM/FM Tuner module.<br />
3. EQ CONTROLS<br />
Three-band equalization control provides ±12dB of cut (decrease) or boost (increase) over the high, mid and<br />
low frequency ranges of the individual channel signals.<br />
HIGH – 10kHz, ±12dB MID – 1kHz, ±12dB LOW – 100Hz, ±12dB<br />
4. PHANTOM POWER SWITCH<br />
This switch turns the phantom power supply on or off for all channels. When the switch is turned on, +22V<br />
DC power is supplied to pins 2 and 3 of each channel’s input connector.<br />
Use phantom power when connecting condenser microphones, which require an external power supply.<br />
NOTE: It is safe to connect most modern dynamic microphones or line level devices to the channel inputs<br />
when phantom power is activated. However, some older ribbon microphones may be damaged by<br />
phantom power, and certain unbalanced line level devices may malfunction or produce an audible<br />
hum when phantom power is active.<br />
