e) Protection. The TP2400 is equipped with advanced protec-

tion systems, which have been extensively checked.

- Soft-start. Connecting the power supply activates a delay cir-

cuit to prevent current peaks during this initial period. This power

supply circuit also includes an anti-parasite filter and an automa-

tic reset Breaker to protect against excess consumption.

- Short-circuit: If one or more speaker lines are short circuited

(+ connected to -) the system disconnects the corresponding

power module.

- DC. Presence of Direct Current at the speaker output. A spe-

cial designed circuit senses the power output of each of the

channels, disconnecting the power module to protect the louds-

peaker if a DC is detected

- Temperature. Protection against over-heating in the power

modules is controlled by a NTC sensor in contact with the heat

sinks. A protective circuit is activated if they pass pre-set limits

(90°C) resulting in a gradual reduction of the maximum power

within acceptable limits. This situation may indicate a fault in the

ventilation system (blocked or faulty) or abnormal working condi-

tions caused by continued excess input signal.

- Ventilation. The cooling fans are located on the back panel and

can operate at two speeds; the initial speed is at 50% of the maxi-

mum and will be the default. The full speed will be activated if any

of the temperature-sensed elements (power modules and trans-

former) heat over 55ºC. If for any reason, such as obstruction of

the cooling circuit or a fault in the cooling fans, the temperature

increases to dangerous levels (>90°C), the protection circuit will

disconnect the input signal (Red PROTECT LED lit constantly)

until normal conditions are restored. This circuit automatically re-

arms within a few minutes. In this case, immediately revise the

installation or elements that could have been the cause.

- Limiter. A highly efficient Anti-clip Limiter Circuit protects the

speaker output against the danger of Clipping Distortion, the

cause of the majority of breakdowns in speaker systems (burnt-

out or shorted coils). More than 25 years of using anti-clip tech-

niques have shown the efficiency of this circuit, extending the

working life of loudspeakers when operating continuously at full

power.

In addition to this, the possibility of adjusting the limiter thres-

hold by the user (L&R + Sub), enables to independently adapt the

output power of each channel. The output power can be mat-

ched with the power handling of the available loudspeakers, de-

pending on their impedance. This adjust may also help to adapt

the maximum SPL level of the installation to the local regulations.

- Humidity and dust are the two most damaging elements for any

electronic device. Avoid use under these conditions.

- Basic maintenance is limited to inspection and cleaning of the

areas most affected by the air current generated by the cooling

fan at least once a year, or whenever any obstruction is observed

in the front air outlet grille.
