Channel Indicators:
Maintenance
Bridge mode (yellow) indicates if two channels are bridged using the DIP-switch on
the rear panel.
CPL, Current Peak Limiter (orange), when flashing indicates the maximum possible
current draw has been reached.
CPL, Current Peak Limiter (orange), when constant indicates excessive current draw
caused by a short circuit on the output or very low operational impedance. MUTE LED
will illuminate and the output will mute for 6 seconds before re-meauring the output
impedance. This will continue until the short circuit is removed. CPL remains constant
orange in a fault condition only when an input signal is present.
Temperature (yellow) warning is indicated by a flashing LED. If the amplifier goes into
thermal protect output muted), the TEM LED illuminates constant yellow and the red
MUTE LED illuminates.
VHF, Very High Frequency protection(yellow) indicates that potentially harmful
continuous high frequencies have been detected on the input signal. The output is
muted MUTE LED on).
Hardware fault is indicated when both the CPL and TEM, VHF and MUTE indicators
light up simultaneously. The amplifier requires servicing before placing back in
operation.
During normal operation your TD14000 amplifier will provide trouble-free service. The
only user maintenance required I to periodically vacuum clean the foam dust-filters
behind the front grille.
In some extreme cases it may be necessary for authorized service personnel to clean
the inside of the amplifier. These conditions usually occur after prolonged use in extreme
environments such as those using “cracked oil” smoke machines. If you are using your
amplifier in a heavy duty application, it is recommended to have your amplifier serviced
every 3 years purely a preventative action.
