1. XLR Mic Input Connectors (Channels 1-2) – Use these XLR jacks to connect low impedance
microphones, or low level signals from direct boxes, to the built-in mic preamps.
2. 1/4" Line Input Connector (Channel 1) – Use this 1/4" jack to connect instrument or audio
sources with line level signals.
3. USB WIRELESS Input – Connect the optional Samson XPD digital wireless USB receiver to
this input. The wireless receiver gets its power from the XP300, so no additional power
supply is needed. The input is routed to the CH 2 VOL control.
Note: The USB connector is for the Samson XPD receiver only. The connector is not
designed to charge smartphones, tablets, or similar devices.
4. Stereo Input Channel 3/4 – Use the Left (L) and Right (R) 1/4" inputs or stereo 1/8"
(3.5mm) input to connect stereo line level devices.
5. High Frequency (HF) – The HF knob controls the amount of treble applied to each channel.
The channel's HIGH frequency response is flat when the knob is in the 12 o'clock or "0"
position. Rotating the knob to the right will boost the channel's high frequency response
above 10 kHz up to 15 dB, and rotating it towards the left will cut the high frequency
response up to 15 dB.
6. Low Frequency (LF) – The LF knob controls the amount of bass applied to each channel.
The channel's LOW frequency response is flat when the knob is in the 12 o'clock or "0"
position. Rotating the knob to the right will boost the channel's low frequency response
below 100 Hz up to 15 dB, and rotating it towards the left will cut the low frequency
response up to 15 dB.
7. EFFECTS Knobs – Use the EFFECTS control knobs to add one of the sixteen digital effects
to the Channel 1 or 2 input channels. As the knob is rotated clockwise, the level of signal
sent to the effects bus is increased.
