CONNECTIONS
MAIN OUTPUT (unbalanced) –
Connect to your amp or pedalboard.
HEADPHONE OUTPUT – The headphone
output features a high dynamic range, low-
noise amplifier that is capable of driving low
impedance studio headphones.
POWER
POWER – Power the Bass ZIO using the included 9V supply or a pedalboard power
supply. Note that the supply should be able to source up to 200mA of current. The unit's
high voltage rails and specialized circuit requires more power than typical analog
pedals. The high-performance headphone amplifier also adds to the power consumption
when in use. Using a higher voltage than 9V is not recommended. Without headphones,
the base current draw is around 140mA.

DIRECT OUT – Connect the Bass ZIO directly to a
mixer or audio interface using an XLR cable for
recording or live sound applications. This is a
balanced output signal.
LIFT – If you're getting "hum" on the
direct output, slide the LIFT switch to the
right to lift the internal ground
connection to the DIRECT OUT XLR jack.
