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 475 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 1.5 mm2.

The 12-V continuous positive cable must be connected with the amplifier + cable at the vehicle adapter cable (7 607 622 ...) (see Fig. 7).

- 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

Loudspeaker connections ....................... Fig. 4/5

Direct Aux Input........................................ Fig. 6/6a

Direct Aux Input connection

Connection option in case of missing or occupied AUX input at the car sound system

Various NF sources, such as an MP3 player or a mobile navigation, can be directly connected via a 3.5-mm jack plug at the Direct Aux Input. All signal sources can be listened to at the same time and their volume is adjusted at the respective source device.

Note:

All NF sources must be switched off during in-

stallation and connection!

Installing the jack plug cable

Please use our 5-m jack plug cable with order

number 7 607 001 525 for the connection.

One of its special features is an on/off switch.

Switch position OFF (•):

For installation and deinstallation and no connected NF source.

Switch setting ON: (I / II): Only after an NF source has been connected.

Caution:

For the connection, always adjust the volume

control to minimum and switch off the ampliﬁ er.

If you want to listen to one sound source via

the front and rear loudspeakers, you must connect the Direct Aux inputs with our Y jack plug cable (7 607 001 524), (see Fig. 6).

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 prestage outputs (Fig. 2). This allows for a direct connection at the loudspeaker output of the radio device.

Note:

Unused Out/Input connectors from the PnP cable must be connected (see Fig. 2a *).

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

(If the ampliﬁ er is to be jumpered, continue with the section "Bridged loudspeaker connections" at this point).

As with every audio component, the correct polarisation of ampliﬁ er and loudspeakers is of essentially importance 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,

THA 475 PnP

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 ampliﬁ er is automatically switched on (Auto Remote func-

tion). A remote connecting cable is not needed!

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。

THA 475 PnP

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 1.5 平方毫米的橫截面。

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 7）

- 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。

綜合保險絲（保險絲）

發生誤差時，綜合在擴音器內的保險絲保護功率放大器和整個電氣系統。如果使用替換保險絲，請勿橋接保險絲或以更高電流類型的保險絲替代。
