the left amplifi er channel must be connected with the
left loudspeaker and the right amplifi er channel with
the right loudspeaker.
Bridged loudspeaker connections
Note: Not possible for connection via PnP cable.
The THA 475 PnP amplifi er allows for switching the
channels 1+2 and 3+4 as bridge connection. This allows
the amplifi er to be used for one or several subwoofers
or a mid-range driver. In this confi guration, the amplifi er
combines the right and left channel to a single-channel
output (mono output).
Note:
The amplifi er can add the right and left signal information
only if the right as well as the left RCA connection were
carried out.
Caution:
In a bridge circuit, the amplifi er load must be 4 ohm
or higher. A lower load leads to an overheating or
switch-off of the amplifi er and can cause permanent
damages.
Adjusting the type and range of the frequency
crossovers
With the THA 475 PnP, the type of frequency crossover
(i.e. "Low Pass" or "Hi-Pass") and the desired crossover
frequency can be adjusted. For example, if a pair of
subwoofers is to be connected, low-pass settings are
required. The crossover frequency is dependent upon the
frequency range of the loudspeakers (see recommended
frequency range of the loudspeakers).
High-Pass
At a setting of 250 Hz, the amplifi er has a frequency
range of 250 Hz to 30,000 Hz.
Low-pass frequency control
This control is active if the switch is in the position
"Low-Pass", and allows for setting the desired crossover
frequency.
Example:
At a setting of 150 Hz, the amplifi er has a frequency
range of 10 Hz to 150 Hz.
Radio detection - Auto Remote
With a connection via a PnP INPUT cable, the ampli-
fi er is automatically switched on (Auto Remote func-
tion). A remote connecting cable is not needed!
Power-on indicator
Green LED:
Output stage on, regular operating status.
Red LED:
Output stage is electronically switched off due to an
error.

建議：
擴音器的性能好壞完全基於安裝的好壞。正確的安裝增加您
汽車音響系統的整體性能。THA 擴音器應該由受過專門訓
練的人員進行安裝。如果您要自行安裝，請細讀此安裝說明
書並讓您有充足時間進行安裝。
作為總結，請讓我們略談保健此課題：
當在您的汽車內播放音樂時，請顧慮持續高於 100 分貝的
聲壓水平可以對人類的耳朵造成永久性的傷害，甚至失聰。
運用當今的高性能系統和擴音器配置可讓聲壓水平達到 130
分貝以上。
安全備註
請在進行安裝和連接時遵守以下安全備註。
- 拆開電池的負極！請遵守汽車廠商的安全備註。
- 當您鑽孔時，請確保您沒有損壞任何一件汽車組件。
- 正與負電纜的橫截面不可少過 1.5 平方毫米（美國線規
16）。
- 對於有鋒利邊緣的孔，請使用電纜襯墊。
- 不正確的安裝可以導致電子汽車系統或您的汽車音響系統
發生故障。
安裝和連接指示
為確保意外發生時的安全，THA 475 PnP 必須以專業的方
法鎖定。
當選擇安裝位置時，請選擇一個乾爽的位置以便在冷卻擴音器
時能夠提供足夠的空氣環流。
有關安裝表面必須適合鎖上配備的螺絲，同時能夠給於穩固的
支撐。
