Manley FORCE features four true High Voltage vacuum tube microphone preamps, taken from the incredibly popular and award-winning Manley CORE and housed in an exquisitely sleek chassis hand-built in California

Each channel contains:

7-Segment LED Peak Metering
Selectable Gain, LOW vs HIGH
120Hz High Pass Filter switch
Phase Invert switch
48V Phantom power switch
Input Attenuator (Variable Pad)
Silent Input Level Control (Variable Input Pad)
1/4 ″ DIRECT INPUT
DI input is the same as in Manley SLAM! ® and Manley CORE®, a solid-state circuit with 10 Meg Ohm input impedance perfect for guitar, bass, keyboard etc.
