Ext Speaker
With the switch in the Internal Only position, the Internal (Black & Red wires)
speaker is all that is used. In the In External position, the external
speaker is placed in series with the internal 4 ohm speaker.
Internal (Red and
Black)
This is the bridged output to the speaker. This output is active in both switch
positions. The internal speaker impedance must be greater than 3 ohm.
The red wire is (+) or positive phase, the black wire is (-) or negative phase.
CAUTION:
Both wires have an audio AC voltage on them. DO NOT allow
them to short to ground when the amplifier is on, as this could cause a failure.
NEVER use grounded equipment to measure the speaker output.
External This jack (combination Speakon or ¼ inch TS) is used to connect to the external
speaker. The ¼ in TS plugs into the center hole of the Speakon jack. The
external speaker is only active when the switch is in the In External
position.
NOTE:
We recommend using a 4 ohm external speaker. (You can use an 8 ohm or even
a 16 ohm external speaker; however the volume level from the external speaker
will be slightly lower than the internal speaker.)
