Recommendation:
The performance of an amplifi er can only be as good
as its installation. A correct installation increases the
overall performance of your car sound system. The THA
amplifi er should be installed by a trained person. If you
would to install it yourself, please read these installation
instructions very carefully and allow yourself suffi cient
time for the installation.
In conclusion, allow us a few words about the topic of
health protection:
During the playback of music in your vehicle, please
consider that continuous sound-pressure levels above
100 dB can lead to permanent damages to the human
ear and even to loss of hearing. Using today's highperformance systems and loudspeaker confi gurations
allows for reaching sound-pressure levels above
130 dB.
Safety notes
Please observe the following safety notes
during the installation and connection.
- Disconnect the negative pole of the battery! Observe
the safety notes of the vehicle manufacturer.
- When you drill holes, ensure that you do not damage
any vehicle components.
- The cross section of the plus and minus cable may
not be less than 1.5 mm
- Use cable glands for holes with sharp edges.
- An incorrect installation can result in malfunctions
of the electronic vehicle systems or your car sound
system.
Installation and connection instructions
With respect to accident safety, the THA 1250 PnP must
be secured in a professional way.
When selecting the installation location, select a dry
location that offers suffi cient air circulation for cooling
the amplifi er.
The installation surface must be suitable to accept the
accompanying screws and provide a fi rm support.

(A.W.G. 16).
The amplifi er power cable must be fi tted with a
fuse no more than 30 cm from the battery (see Fig. 2a)
to protect the vehicle battery in case of a short circuit
between power amplifi er and battery. The fuse of the
amplifi er protects only the amplifi er, not the vehicle
battery.
Use loudspeakers with 2-4 Ω impedance (see table or
installation drawing). Observe the maximum power
handling capacity (music output). Do not connect
loudspeakers to earth, use only the referenced
terminals.

Plus / minus connection
- We recommend a minimum cross section of 2.5 mm
(A.W.G. 13).
The 12-V continuous positive cable must be
connected with the amplifi er + cable at the
vehicle adapter cable (7 607 622 ...) (see Fig.
6).

- Route a commercially available positive cable to the
battery and connect it via fuse holder 30 cm from
the battery.
- Use cable glands for holes with sharp edges.
- Securely fasten commercially available minus cables to
a noise-free earth point (chassis screw, chassis metal)
(not to the minus pole of the battery).
- Scrap the contact surfaces of the earth point until
they are bright and grease with graphite grease.
Integrated fuses (Fuse)
The fuses integrated in the amplifi er protect the power
amplifi er and the entire electrical system in case of an
error. If a replacement fuse is used, never bridge fuses
or replace them with a type with higher current.
Connection examples
Connection of the voltage supply .................. Fig. 2, 2a
Connection to car sound system
with cinch output ..........................................Fig. 3
Loudspeaker connections ............................Fig. 4, 4a
Remote connection of the amplifi er with
+12V
switchable +12 V voltage source.
This allows the amplifi er to be switched on and off using
the on/off-switch of the radio device.
Note:
If the connection is made using a PnP-INPUT cable,
the switch-on is performed automatically.
! As a special feature, +12 V/200 mA are now available
as output switching voltage at the remote input/output after automatic switch-on.
High-level connections (via PnP High-Inputcable
only)
The amplifi er features high-level connections (High Input)
to be able to connect to radio devices without pre-stage
outputs (Fig. 2a). This allows for a direct connection at
the loudspeaker output of the radio device.
Level control
The Level control is used to adjust the input sensitivity
of the power amplifi er to the output voltage of your car
sound system.
The adjustment range is from 0.3 V to 8 V.
A few important explanations in this context:
By turning the control clockwise, the input sensitivity of
the amplifi er and, therefore, also the volume increases.
However, this is not a volume control; no further amplifi er
output can be achieved in the end position, even if it
may sound like that at the beginning. The system merely
increases the volume faster if the volume control of the
car sound system is turned up.
Loudspeaker connections
As with every audio component, the correct polarisation
of amplifi er and loudspeakers is of essentially impor tance
for a good bass response. For this reason, ensure that
the positive (+) connection of the amplifi er is connected
with the positive connection (+) of the loudspeaker; the
same applies to the negative (-) connections. In addition,
the left amplifi er channel must be connected with the
left loudspeaker and the right amplifi er channel with
the right loudspeaker.
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.
Adjusting the type and range of the frequency
crossovers
With the THA 1250 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.
Bass boost
The bass boost control on the remote control is used to adjust
the bass response of the amplifi er. The adjustment range is
from 0 dB to +12 dB (see Fig. 7).
The control is active only if "LOW Pass, ON" is switched on.
Radio detection - Auto Remote
With a connection via a PnP INPUT cable, the amplifi er
is automatically switched on (Auto Remote function).
A remote connecting cable is not needed!
Power-on indicator (POWER / PROTECTION)
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 1250 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。
擴音器的電源電纜在離開電池不超過 30 釐米的位置必
須裝上一個保險絲（請看圖 2a）以便在功率放大器和電池
之間發生短路時保護汽車電池。擴音器的保險絲只保護擴音
器，並沒有保護汽車電池。
使用 2-4 Ω 阻抗的喇叭（看製錶或安裝圖）。遵守功率電
容的最大極限(音樂輸出)。不要把喇叭接地，只使用參考端
子。

正/負連接
- 我們建議至少 2.5 平方毫米的橫截面（A.W.G. 13）。
12 伏特連續正極電纜必須使用擴音器 + 電纜連接至
汽車適配器電纜（7 607 622 ...）（看圖 6）。
- 接駁商用的正極電纜至電池並經由離電池 30 公分的保險
絲支架連接。
- 對於有鋒利邊緣的孔，請使用電纜襯墊。
- 紮牢商用負極電纜至無噪聲的接地點（底盤螺旋、底盤金
屬）（不是至電池的負極）。
- 敲打接地點的接觸表面直到光亮並以石墨脂潤滑。
