pg 3
Connect the included IEC cable to Zuma 
and plug the other end into an AC power 
outlet. Zuma operates worldwide (120V, 
240V, 100V) with the appropriate IEC 
cable.
Zuma will power 
most effects pedals 
on the market, 
including all 
Strymon pedals. 
Check with each 
pedal manufacturer 
for recommended 
voltage, polarity, and 
required current. 
For pedals that 
have unique power 
requirements 
(more than 500mA 
of current, other 
voltages such as 
24V), you can find 
configuration details 
here: strymon.net/
support/zuma
24V DC OUT:
Connect a Strymon 
Ojai (sold separately) 
to the 24V DC OUT jack 
and gain additional 
outputs for your 
pedals.
LED INDICATOR: 
Each output features 
an LED indicator. 
LED illuminates 
green when a pedal 
cable is plugged 
in. LED will turn 
off if cable is 
unplugged, or the 
current draw on the 
output exceeds the 
maximum amount 
available.
Getting Started
Connect Your Pedals
A total of nine high or low-current pedals can be connected to Zuma. Additional outputs 
can be added by connecting a Strymon Ojai (sold separately) to the 24V OUT jack.
PEDAL OUTPUTS:  Connect up to nine effects pedals with the included 
5.5mm x 2.1mm pedal cables. Each output is dual-isolated for noise-
free operation.
9V OUTPUTS: 
Seven outputs provide 
9V DC, center negative 
polarity, each with 500mA 
of available current.
ADJUSTABLE OUTPUTS: 
Two outputs provide selectable 
9V, 12V, or 18V DC, each with 
center negative polarity. Each 
output provides 500mA of 
available current at 9V, 375mA at 
12V, and 250mA at 18V.
