TP-LINK P912A Manuale Utente
Note:
When the temperature of heat sink exceeds 105°C, the protection
circuit is activated and the output is disconnected from the
circuit is activated and the output is disconnected from the
circuit. The signal automatically begins to be output as the
temperature goes down. In such a case, confirm whether or not
unit is overloaded or operated on an excessive output.

Do not block cover ventilation holes.

The amplifier should not be placed in areas;
1. with poor ventilation.
2. exposed to direct sunlight.
3. with high ambient temperature or adjacent to heat-generating
equipment.
4. with high humidity or dusty levels.
5. susceptible to vibration.
The speaker outputs of the amplifier are 4
, 8
, 25V and 70V.
Connect speakers to one of these outputs.
Class 2 wiring may be used.
Class 2 wiring may be used.
Since these outputs consist of 8
, 25V and 70V via the output
transformer (matching transformer) and direct output of 4
, the
connecting method differs in each case. See the following diagrams.
Note: Impedances indicated below imply total speaker system
(load) impedance.

When connecting speakers to any one of the outputs of 8 O, 25V
or 70V (BALANCED TRANSFORMER OUTPUT);
Note:
In this case, the LOW-CUT SWITCH should be in "CUT" posi-
tion. This amplifier is characteristically flat even in the low fre-
quency range. Therefore, in TRANS OUTPUT, the acoustic
effect and frequency-response characteristics may be altered.

In TRANS OUTPUT, cut off unnecessary low frequency to ob-
tain the best acoustic condition.
