TROUBLESHOOTING
I am using the 215PCM setup for biamp operation, but my mid- and high-frequency sound seems to be gone-
• Make sure the Mode Switch is in the correct position for your intended application.
• Be sure you are using only the upper Speakon for 4-wire biamp connection.
• If using 2-wire Speakon cables to connect to your biamp cabinet, use the upper Speakon for HF and the
lower Speakon for MF.
• Verify the Processor configuration loaded in the Top Box Processor is as desired.
I’m trying to biamp two separate top boxes and it doesn’t seem to be working-
• There are only two channels of amplification available to the Top Boxes. You can not run two biamp devices,
as this would require four channels of amplification. The 215PCM supports two channels of amplification for
Top Boxes.
• QSC 8 ohm top boxes have dual-, feed-through Speakons that allow 1 or 2 additional top boxes to be daisy-
chained.
I used my 215PCM with another PC that had a later version of Signal Manager running on it. Now my other PC
(with the older Signal Manager version) won’t recognize my configurations-
• When a configuration is opened by a newer version of Signal Manager software than the one used to
create it, the configuration is “updated” to be compatible with the newer version.
• You will have to keep the version of the Signal Manager software the same for all PC’s used to configure
the 215PCM. This will ensure reliable, predictable results when using multiple PCs to configure the
Processors.
My Inputs are hooked up to the 215PCM, and the Top Boxes sound great. But, the subwoofer doesn’t seem to
be working-
• Check the MODE SWITCH position. In COMBINATION MODE, inputs for CH1 and CH2 are summed and routed
to the Subwoofer Processor. If set to DISCRETE MODE, the Subwoofer Processor is disconnected from CH1 and
CH2 inputs, and connected to INPUT 3. And if Input 3 has no input signal connected to it, then the Subwoofer
will have no signal.
• If operating in DISCRETE MODE, make sure the Subwoofer input signal is connected to Input 3.
• Verify the Processor configuration loaded in the Subwoofer Processor is as desired.
