1. Channel Input Jacks (channels 1 - 4)
MIC – XLR connector – Use these XLR jacks to connect low impedance microphones
to the XP1000’s built-in mic preamps.
LINE - ¼” phone connector – Use these ¼” jacks to connect instrument or audio
sources with line-level signals to the XP1000. You can connect the outputs from
acoustic guitar active pickups, keyboards, drum machines, CD/MP3/TAPE players
and other units with line level outputs here.
2. USB WIRELESS Input* – Connect the optional Samson Stage XPD1 digital wireless
USB receiver to this input. The wireless receiver gets its power from the XP1000,
so no additional power supply is needed.
The WIRELESS input is routed to the
channel 4 LEVEL control.
3. MIC/LINE switch (channels 1 - 4) -The MIC position changes the gain of both input
jacks to MIC level. The LINE position reduces the gain of both jacks by 26dB to
line level.
4. LIMIT/COMP switch - Set the LIMIT/COMP switch to the COMP position to apply
compression or set it to the LIMIT position to apply limiting.
Compressors are used to control the dynamic range of a signal, which offers
a variety of benefits including leveling a signal and increasing the loudness
of a sound system to name.
A Limiter is a specific form of a compressor configured to prevent peaks and for
general overload protection.
* The USB connector is for the Stage XPD1 receiver only. The connector is not designed
to charge smartphones, tablets, or similar devices.
