Problem
T4S/T8S is plugged
in, power switch is on,
but no power.
T4S/T8S is on, but
there is no sound.
What to do
• Make sure you have power at the AC outlet. Try operating a lamp or other
equipment from the same AC outlet or test the outlet using an AC outlet tester.
If using the T4S with an L1® Model II or 1S system:
• Make sure the ToneMatch® cable is properly connected to the mixer and the L1
power stand.
• Verify that the power cord plug is fully inserted into the power stand and the AC
(mains) outlet.
• Make sure the L1 power stand is turned on and the power LED is blue.
• Make sure the Master volume control is turned up.
• Verify that the input channel(s) you want to hear is not muted.
• Check that the Volume control is turned up for the channel you want to hear.
• Make sure the appropriate input channel Trim control has been turned up enough
so that the LED is green (indicating that there is a strong input signal).
• Check the Prefs (Preference) Input and Output level meters to confirm that there
is a signal at both the input and output stages.
• Make sure volume control is turned up on your input source (instrument).
• Connect your input source (instrument) to the mixer using a different cable.
• Plug your input source (instrument) directly into the L1 power stand or a different
amplifier to make sure the source is working.
• Turn the mixer off and wait 30 seconds. Then turn mixer on again.
If using the T4S with an L1 Model II or 1S system:
• Turn off the power stand, re-seat the ToneMatch cable plug in the ToneMatch
port, and turn on the power stand again.
• If available, try a different ToneMatch cable. If another ToneMatch cable is not
available, try a standard ethernet cable.
• Connect the T4S/T8S Master output to the Analog Input on the power stand
using a 1/4" phone plug cable. Turn up the power stand Trim control, and verify
that you hear sound.
• Make sure power LED on power stand is blue. If LED is red, please call the Bose
Product and Technical Support Team directly at (877) 335-2673.
