1.1 power on / off

to power on your OP-Z, turn the yellow knob located on the left side of the unit clockwise, until you feel and hear a click. the track leds will light up in a rainbow pattern and the internal speaker will play a startup sound. OP-Z is now ready to be used.

keep turning the knob to adjust the master volume. always make sure to be careful with your ears.
to power off OP-Z, turn the knob counterclockwise, past the click.

note: all OP-Z data is stored on-the-fly, so everything will still be there next time you power on your unit.
it’s a good habit to occasionally back-up OP-Z using disk mode.

1.2 charging the battery

OP-Z has an internal rechargeable battery which can be charged using the included usb-c cable. connect the unit to a computer or any standard usb charger.

keep OP-Z connected for as long as you want to charge. while charging and turned off the motion led will be blinking green.
when connected and fully charged the motion led will be solid green.

to check the battery level press and hold screen. the track led lights will light up to indicate the charge level, from 1 to 16.
note: when paired with the app, battery level is shown in the main interface.

pro-tip: usb charging can be disabled by holding screen and pressing e2 (the right- most piano key). this can sometimes cancel noise related to usb. you can also get a dedicated ground loop noise isolator.
when holding screen in this mode the track led lights are yellow.

1.3 replacing the battery

the internal battery is easy to replace. simply remove the back plate to access it. 

OP-Z uses a custom battery design. do not attempt to use any other battery to power your unit. 

replacement / backup batteries are sold separately.

1.4 low battery indicator 

(available since os 1.2.12) 

when OP-Z is about to run out of battery, it displays a led animation every 30 seconds. time to charge!

1.5 inputs and outputs

in its standard configuration OP-Z has two ports located on the right hand side of the unit:

• main audio for headphones, headset or line out.
• usb-c port for charging, file transfers and midi.

on the top side you find four expansion ports, for use with a physical hardware module (sold separately). 
more info about the modules and how to expand the hardware will be available soon.

on the left side, next to the volume knob, is the microphone and mic led indicator.
read more about how to use the microphone here.

note: make sure never to feed phantom power in to OP-Z as this will damage the electronics and void the warranty.
