Connect one or two 8-ohm speakers or one (only) 4-ohm speaker to each channel.
When connecting the Speakon’s™, push them in firmly. Push the tab and pull to disconnect.
User tip: To connect two (8-ohm) speakers to one or both of the DJM806’s powered output
channels via the Speakon™ connectors, run a single Speakon™ -equipped cable, e.g. Yorkville
model SP2-25SS or SP2-50SS with Speakons™ at both ends (most higher-powered speaker
enclosures now feature Speakons™ as well) from the DJM806 to one of the enclosures. Now
run a second cable from one cabinet to the next via their dual, parallel inputs.
Power Amplifier Protection
The DJM806’s power amplifier is protected from damage due to open, shorted or
excessively low speaker loads. It will continue to run into a low, less than 4-ohms,
overall speaker impedance or even a total short-circuit for a brief time, however the
amplifier’s defense system will be activated. First, the built-in limiter will reduce output
power levels and the fan speed may increase. Then, if the condition worsens, a thermal
protection circuit will shut the power amplifier down. When this happens, check your
system for restricted air intake/exhaust at the DJM806. Also check for shorted cables or
connectors and/or reduce the number of speakers being driven. In a few minutes when
it has had a chance to cool down, power amp function will resume.
User tip:
a) If the power amplifier shuts down as above, the mixer section will continue to
function. This means that, if the DJM806’s power amp fails to come back on
(unlikely) and you have a spare power amplifier available, you can connect it to
the DJM806 via the Main Out connectors.
b) Because the amplifier is also protected against open-circuit conditions, you may
use the DJM806 without any speakers connected, for example if you wanted to
do some recording.
The DJM806 power amplifier also features speaker protection in case of DC-off-
set. This is a very unlikely occurrence given the amp’s inherently stable design, but
should it happen, the output power is instantly shorted to ground and the speakers
will be protected. The AC mains breaker on the back panel will blow in response to
this condition (among others). If your breaker open more than once in a short space
of time and the problem does not appear to be AC overload (see below), switch the
power off and take your DJM806 to a Yorkville dealer for service.
AC Power Circuit-Breaker
Located on the back panel near the Speaker connectors, this circuit-breaker’s (reset)
main function is to shut the DJM806 down completely in case of an AC power over-
load. If, for example, the unit were accidentally connected to a high-voltage power
outlet, this breaker would open as soon as the DJM806 Power switch was flipped on.
If this breaker opens immediately, try plugging the DJM806 into another power outlet.
Also, see above regarding DC-offset speaker protection.
Rack Mounting
To rack-mount the DJM806 you will need to purchase the accessory RK812 rack ears.
Then, simply remove the three screws holding each of the DJM806’s two end mold-
ings in place and use the screws to mount the rack ears to the sides of the mixer.
