Warranty

We provide manufacturer’s warranty for 12 months from the date of sale for Blaupunkt products purchased within India.
Recommendation
The performance of an amplier can only be as good as its installation. Correct installation increases the overall performance of your car sound system. The THA amplier should be installed by a trained person. If you would like to install it yourself, please read these installation instructions very carefully and allow yourself sufficient time for the installation.
In conclusion, allow us a few words about the topic of health protection:
During playback of music in your vehicle, please consider that continuous sound-pressure levels above 100 dB can lead to permanent damage of the human ear & in some cases loss of hearing. Using today’s highperformance systems and loudspeaker congurations 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 terminal of the battery! Observe safety notes of the vehicle manufacturer.
• When you drill holes, ensure that you do not damage any vehicle components.
• Please use minimum 10AWG power & ground cable with a fuse located within 18 inches of the battery.
• Use cable glands for holes with sharp edges.
• Incorrect installation can result in malfunction of vehicle electronic systems or sound system.

Installation and connection instructions

With respect to accident safety, the THA 500.1 must be secured fastened at its mounting location.
When selecting the installation location, select a dry location that offers sufficient air circulation for cooling the amplier.
The THA 500.1 must not be installed on rear shelves, rear seats or other locations that are open to the passenger cabin.
The installation location must be suitable to accept the accompanying screws and provide a rm support.
The amplier power cable must be tted with a fuse no more than 45 cms from the battery to protect the vehicle battery in case of a short circuit between power amplier and battery. The fuse of the amplier protects only the amplier, not the vehicle battery.
Use loudspeakers with 2 – 4 Ohms impedance (see table or installation drawing). Do not connect loudspeakers to ground, use only the referenced terminals.

Audio inputs (see Fig. 3)
You can select between 2 different audio inputs;

• Cinch (RCA)
• Hi level (loudspeaker connections)

Use only one of the audio inputs; otherwise, it may lead to audio interference.
The preamplier outputs are connected to the cinch (RCA) socketsj) via a shielded sound cable.
With control via the loudspeaker outputs, the input connections of pos. ②/③ are fed to the closest loudspeaker cables (front or rear) on the left and right.
They are separated and connected to the input connections. The polarity of the +or – connections must be observed. Bridge output stages (BTL) can also be connected directly without an additional adapter.

Positive / negative connection

• We recommend a minimum cross section of 10 AWG
• Route commercially available positive cable to the battery and connect via fuse holder.
• Use cable glands for holes with sharp edges.
• Securely fasten commercially available negative cables to a noise-free ground point (chassis screw, chassis metal) not to the negative pole of the battery.
• Scrape the contact surfaces of the ground point until they are bright and grease with graphite grease.

Integrated fuses (Fuse)
The fuses integrated in the amplier (Fuse) protect the power amplier 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
Audio inputs…………………………………………….Fig. 3
Loudspeaker connections……………………..Fig. 4/5

Remote connection of the amplier with switchable +12V voltage source.
This allows the amplier to be switched on and off using the on/off-switch of the radio device.

Level control
The Level control is used to adjust the input sensitivity of the power amplier to the output voltage of your car ound system preamplier output.
The adjustment range is from 0.2 V to 5V.
If a car sound system of a third party manufacturer is connected, the input sensitivity must be adjusted corresponding to the manufacturer data.
An important explanation in this context:
By turning the control clockwise, the input sensitivity of the amplier and, therefore, also the volume increases. However, this is not a volume control; no further amplier output can be achieved in the full 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.

DC Offset- 4
When connecting to an OE radio, it may not be possible to connect the remote turn on lead on the amplier, please use the high level input available on the side panel & turn on DC Offset to automatically turn on/off the amplier when the OE radio is turned on / off.

Loudspeaker connections

As with every audio component, the correct polarity of amplier and loudspeakers is important for a good bass response. For this reason, ensure that the positive (+) connection of the amplier is connected with the positive connection (+) of the loudspeaker; the same applies to the negative (-) connections. In addition, the left amplier channel must be connected with the left loudspeaker and the right amplier channel with the right loudspeaker.
Caution:
Amplier load must not be lower than 2 Ohms. A lower load leads to overheating & cause the amplier to switch off & can cause permanent damage.
Adjusting the type and range of the frequency crossovers
With the THA 500.1, the type of frequency crossover (i.e. “Low Pass”) and the desired frequency can be adjusted. For example, if a subwoofer is connected, the low-pass settings shown are required (Fig. 3). The frequency is dependent upon the f requency range o f the loudspeakers (see recommended frequency range of the loudspeakers).
Low-pass frequency control
This control is active if the switch is in the position “LowPass”, and allows for setting the desired entry frequency.
Example: At a setting of 120Hz, the amplier has a frequency range of 50Hz to 500Hz. ( I dea l fo r Subwoofers).
Bass boost
The bass boost control is used to adjust the bass response of the amplier.
The setting options are: 0 dB / +6 dB.
Power-on indicator (PWR / PRO)
Green LED: Output stage on, regular operating status.
Red LED: Output stage is electronically switched off due to an error.
