Samson S-MAX MD1 Pro Single Channel Passive Direct Box - Manual (Page 6)

Connecting Speaker Level Signals
The MD1 Pro provides the capability of tapping off the signals from amplifiers, such as the output of a
guitar amp or any power amplifier. You can even use MD1 Pro to connect to the speaker output of a con-
sumer stereo system to a mixer or PA system.
WARNING: Be sure that the pad switch is set to the -30dB position before connecting the signal from the output
of any amplifier.
The following diagram shows how to connect the powered output of a guitar amplifier to a mixer.
The MD1 Pro can accept signals up to
40 volts when the pad switch is in the
-30dB position. Please use the following
chart to calculate the maximum power
output based on output impedance that
will safely work with the MD1 Pro:
