Each can is capable of projecting a beam angle from 14° to 36°. To adjust, turn the front focal
lens anti-clockwise for a focused spot effect or turn clockwise for a dilated wash effect.

Operation:
The PB-COB can operate in stand-alone, master, slave or DMX modes.
Stand-alone:
For stand-alone display show, Auto, sound-activated or manual colour mode may be selected.
Simply select  (auto mode) or  (sound activate mode) from the menu and select if you
want PAR cans only (XX or XX), Flash only (XX or XX) or PAR cans and flash (XX or
XX). For auto modes, speed (to ) can be set after the preferred mode is confirmed.
For manual colour modes, select  and enter each RGBW colour mixing value and strobe
speed, if required.
Master/Slave:
More than one units of PB-COB can be operated together via a DMX link. To set a unit as
master, select  from the menu follow by , select  to enable unit as master.
In addition to mirroring the master unit effect, all slave units can also perform a sequential
chase. In order to perform the sequential chase correctly, all slave units need to have their ID
value set accordingly. The master unit will recognize slave units in order of ID value, for
example a setup of four slave units with address value of 1,2,3,4 with be the same as
1,12,24,56.
Synchronise mode:
Two units of PB-COB can be synchronised with each other via a DMX connection. When under
synchronised mode, both units will share the same speed, pattern or sound activation but
display a different light show. To enter synchronised mode, simply select  from the menu
and choose from  for synchronized auto mode or  for synchronized sound-activated
mode.
DMX mode:
The PB-COB can be controlled by DMX signal, simply connect the DMX signal source to the
DMX in at the rear of the unit via a balanced XLR lead. Extra fixtures can be controlled by the
same DMX signal by looping through the DMX out on the PB-COB. To enter DMX mode, select
from the menu and choose which channel mode you wish to use (3, 6 or 28 channel
mode). Confirm the correct DMX start address. A flashing address value indicates that the unit
has correctly entered DMX mode and is awaiting a DMX signal. The DMX address value will
remain lit as soon as DMX signal is detected from the DMX connection.

Foot Controller:
PB-COB uses wireless technology to allow wire-free control from the foot controller.
This greatly increases the flexibility for light set up and controlling, great for mobile gigs and
performances.
Wireless foot control is powered by a single A23 cell. The battery compartment is located at
the bottom of the foot controller (a Philips tip screwdriver is required to open the
compartment).
To enable the wireless function on the PB-COB unit, select > from the menu and
select yes to confirm. Make sure both antennas are pointed upward from the foot controller
and from the PB-COB unit. Now the PB-COB is ready to be controlled by the foot controller.
