Care and Maintenance
Problem What to do
Poor quality sound from a
microphone or instrument
connected to the T4S/T8S.
• Make sure there is no unwanted zEQ or Para EQ equalization applied.
• Verify that you have selected an appropriate ToneMatch® mixer preset
for your microphone/instrument. If you do not want to use a ToneMatch
mixer preset, make sure ToneMatch is set to Flat.
• Make sure there are no unwanted eects (Comp/Gate, Mod, Delay,
Reverb) on your input channel. Check the Status in the Prefs menu for
any currently active eects.
• Check that the T4S/T8S input Trim is adjusted properly for your
microphone/instrument. The signal LED should be green; if the LED is
red, lower the Trim level until it is green.
• Try a dierent microphone or instrument cable.
• Check the cable connecting your microphone or instrument to the T4S/
T8S mixer. Make sure the cable plug is fully inserted into the microphone/
instrument output connector and the T4S/T8S input connector.
• Check the settings (if any) on your microphone or instrument.
• Check the batteries (if any) in your instrument or microphone.
Not hearing any eects. • Check that you pressed the correct CH Edit button.
• Make sure the FX Mute button is not pressed for the channel in question.
T4S/T8S not responding to
control knobs.
• Turn o the mixer. Wait 30 seconds and turn mixer on again.
Master volume control has no
eect.
• Verify that the Master output is configured for Post Master Volume
operation in the Prefs menu under Master Out.
With nothing plugged into the
T4S/T8S input connectors, a
slight hum or buzz is heard
from the L1® system.
• Plug the T4S/T8S and the L1 power stand into the same AC (mains) outlet.
• Using an AC outlet tester, test the AC outlet that the T4S/T8S and/or the
L1 power stand is plugged into for reversed or open (hot, neutral, and/or
ground) contacts.
• If using an extension cord, make sure that the cord is also tested as
above.
Too much (or not enough)
bass, mid-range, or high
frequencies.
• Make sure there is no unwanted zEQ or Para EQ equalization applied.
• Verify that you have selected an appropriate ToneMatch mixer preset
for your microphone/instrument. If you do not want to use a ToneMatch
mixer preset, make sure ToneMatch is set to Flat in the Utility category.
Poor-sounding playback of a
stereo recording using a CD
player, MP3 player, or other
such device.
• Connect the left channel of the device to Aux input 5 and the right
channel to Aux input 6 (or 9/10 for T8S). Aux inputs 5/6 (or 9/10) are
designed for line-level inputs.
• Disable any extended bass or EQ features when using CD or mobile
device.
• If you are using recording software on a computer, check the software
requirements. You may need to configure the software settings for
48kHz/24-bit operation.
