Chapter 3: DL1608 Hardware : Rear Panel
Power Connector
The DL1608 has a universal external power supply that accepts any AC voltage
ranging from 100 VAC to 240 VAC. No need for voltage select switches. It will work
virtually anywhere in the world. That’s why we call it a “Planet Earth” power supply!
It is less susceptible to voltage sags or spikes compared to conventional power
supplies, and provides greater electromagnetic isolation and better protection
against AC line noise.
An external 12V DC power supply [aka The Power Block] and a line cord are included
with the mixer. A locking barrel connector resides at the end of the cord attached to
The Power Block. Attach it to the power connector on the DL1608 and rotate the
outer ring clockwise to lock. Do not over-tighten! Screw until there is resistance, then
stop. Connect the female end of the line cord to The Power Block and plug the male
end into a live grounded AC outlet. An LED on The Power Block will illuminate green
to indicate success (whether the mixer is powered on or not).
Warning:
Disconnecting the plug’s ground pin is dangerous. Don’t do it!
In fact, it’s a bad idea to remove
anything
from (or add anything to)
The Power Block or line cord. Again, don’t do it!
Power Switch
Press the top of this rocker switch in to turn the DL1608 on and
press the bottom of
this switch to turn the DL1608 off.
As a general guide, the DL1608 should be turned on first, before any
external power amplifiers or powered speakers. As such, it should also be
turned off last. This will reduce the possibility of any turn-on or turn-off
thumps in the PA.
