Frequently Asked Questions - GTA 5350 BLAUPUNKT

How to install the GTA 5350 amplifier in my car?

Before any installation, disconnect the negative terminal of the battery. Securely mount the amplifier in a dry, well-ventilated area (under a seat or in the trunk). Use power cables with a minimum cross-section of 6 mm². Place a fuse within 30 cm of the battery. Connect the remote wire to a switchable +12 V source (e.g., the head unit's remote wire). Finally, connect the speakers respecting polarity.

What speaker impedance can I use?

The amplifier is stable at 2 ohms. You can use speakers from 2 to 4 ohms. In bridged mode, the minimum impedance is 4 ohms to avoid overheating.

How to bridge the amplifier for a subwoofer?

For a bridged connection, use channels 1+2 or 3+4. Connect the subwoofer positive to the positive terminal of channel 1 (or 3) and the negative to the negative terminal of channel 2 (or 4). Ensure the subwoofer impedance is at least 4 ohms. The RCA inputs must be connected to both channels involved.

What does the red 'PROTECT' light mean?

The red light indicates that the amplifier has gone into protection due to a fault (short circuit, overheating, too low impedance). Check the connections, speaker impedance, and ventilation. Once the problem is resolved, restart the amplifier.

How to adjust the gain (input sensitivity)?

The gain control adjusts the input sensitivity (0.3 V to 8 V) to the head unit's output voltage. Turn it clockwise to increase sensitivity. Caution: this is not a volume control; too high a setting can cause distortion. Adjust it while listening to music at moderate volume until you get clear sound without clipping.

Which filters to use for full-range speakers and a subwoofer?

For full-range speakers (front/rear), use the high-pass filter set around 80-100 Hz to avoid low frequencies. For the subwoofer, use the low-pass filter set between 80 and 120 Hz. The GTA 5350 allows these filters to be adjusted from 40 to 450 Hz.

What is the real RMS power of the amplifier?

The RMS (continuous) power is 4 x 40 W + 1 x 160 W at 4 ohms, and 4 x 60 W + 1 x 250 W at 2 ohms. These values are more realistic than max power.

Can I use the amplifier with a head unit without RCA outputs?

If your head unit only has speaker outputs, you will need a high-level/RCA adapter. The GTA 5350 is designed for Cinch inputs. Ideally, use a head unit with RCA outputs.

How to avoid amplifier overheating?

Ensure good ventilation around the amplifier. Do not install it in a confined space. Avoid operating it with too low impedance (below 2 ohms) or in bridged mode with less than 4 ohms. If the red light comes on, let it cool down.

What cables to use for power?

Use cables with a minimum cross-section of 6 mm² for power (+ and -). The positive cable must be connected to the battery via a fuse holder. The negative cable must be attached to a clean ground point on the chassis (not directly to the battery).

Recommendation:

A power amplifier's performance is only as good as its installation. Proper installation will maximise the overall performance of your audio system. We recommend that you have our product installed professionally. Should you decide to install the amplifier yourself, however, please read through these instructions carefully, and take your time over the installation.

Finally, a word about your health: please bear in mind when playing music in your car that sustained sound levels above 100 dB can damage your hearing and may even result in total hearing loss. Modern high-performance systems and high-quality loudspeaker configurations are quite capable of generating noise levels above 130 dB

Safety precautions Instructions for installation and connection

Fit a fuse in the amplifier power line no more than 30~cm from the vehicle battery, in order to protect the battery in the event of a short-circuit between it and the power amplifier. The amplifier's own fuse protects the amplifier itself, but not the car battery. Disconnect the negative terminal of the battery before carrying out installation and connection work.

Observe the vehicle manufacturer's safety instructions (regarding airbags, alarm systems, trip computers, vehicle immobilisers).

The final stage must be installed professionally for reasons of safety. The mounting surface must be suitable for the screws provided, and must provide firm support.

When drilling holes, take care to avoid damage to vehicle components (battery, cables, fuse boxes).

Fit the amplifier in a suitable location, e.g. beneath the seats or in the trunk (Fig. 1). The mounting location must also be dry, and provide sufficient ventilation for cooling of the amplifier. Use cable grommets when passing cables through holes with sharp edges. Use loudspeakers with an impedance of 2 to 4 (see table or installation drawing). Observe the max. power handling specifications (music output). Do not connect the loudspeakers to ground; only use the terminals provided. The cross-section of the positive and negative cable must be at least 6mm^2 .

GTA 5350 amplifier

The amplifier is suitable for connection to car radios with Cinch connector. Use the Blaupunkt ISO Cinch adapter to connect the amplifier to car radios with ISO connector (7 607 893 093/7 607 855 094).

Positive/negative connection

We recommend a cable cross-section of not less than 6mm^2 . Run a standard commercial positive cable to the battery and connect to the fuse holder. Use cable grommets when passing cables through holes with sharp edges. Bolt a standard commercial negative cable to a ground point free of induced noise (car body bolt, body panel) - not to the negative battery pole. Clean the contact surface of the ground point down to bare metal and coat with antiseize graphite petroleum.

Integral fuses

The integral fuses within the amplifier protect the final stage and the entire electrical system in the event of a fault. Never bridge fuses or replace fuses with a higher current rating.

Example connections

Power supply connection Fig. 2.

Connection of car radio with cinch output Fig. 2a.

Loudspeaker connections Fig. 3-5.

Connect remote amplifier connection to switchable +12V power source.

This enables the amplifier to be switched on and off with the radio's On/Off switch.

Level control

The Level control enables the input sensitivity of the final stage to be matched to the output voltage of your car radio preamp output.

The range of adjustment extends from 0.3V to 8V .

Adjust the input sensitivity in accordance with the manufacturer's specifications when connecting the amplifier to other radios.

Important: Turning the Level control clockwise increases the input sensitivity of the amplifier, and thereby also the volume. The Level control is however not a volume control; an increase in volume is not achieved in the maximum position, even if this subjectively appears to be the case. The system merely increases the volume more quickly when the volume is turned up on the radio.

Loudspeaker connections

(If the amplifier is to be connected in a bridged mode, proceed with the section "Bridged loudspeaker connections".)

As with any audio component, connection of the amplifier and speakers with the correct polarity is essential for good bass reproduction. Ensure therefore when connecting that the positive (+) amplifier terminal is connected to the positive (+) loudspeaker terminal. The same applies to the negative (-) terminals. The left-hand amplifier chan

nel must also be connected to the left-hand loudspeaker and the right-hand amplifier channel to the right-hand loudspeaker.

Bridged loudspeaker connections

The GTA can also be bridged in a mono configuration. This enables you to use the amplifier for one or more subwoofer(s) or a mid-range speaker. In this configuration the amplifier sums the right-hand and left-hand channels, delivering a single channel (mono) output.

Note:

The amplifier can sum the right- and left-hand signal information only if both the right- and left-hand RCA connections have been made.

CAUTION:

The amplifier must be presented with a load of 4 Ohms or higher in bridged mode. A lower load will cause the amplifier to overheat or switch off. This can lead to permanent damage of the unit.

INPUT - SUB SELECTOR-MODE

CH 1+2, CH 3+4: To operate the GTA 5350 amplifier in 4-channel mode (stereo front / rear). In this case, all 4 inputs must be connected to the source device (car radio).

CH 1+2: To operate the GTA 5350 amplifier in 4-channel mode (stereo) with 2 input signals. In this case, CH1 and CH2 must be used. The usual Y-cable is not needed with this configuration.

Adjustment of the type and range of the cross-over frequencies

The type of crossover (i.e. "low-pass" or "hipass") and the desired crossover frequency can be selected on the GTA 5350. If, for example, you wish to drive a pair of subwoofoers, connect in accordance with the low-pass diagram (fig. 2a). The crossover frequency is dependent upon the loudspeaker frequency range (consult the loudspeaker manufacturer's data for the recommended frequency range).

"High- Pass" frequency control

This control is active when the switch is in the "Hi-pass" position, and permits selection of the desired crossover frequency. Example: at a of 40Hz , the loudspeaker has a frequency range of 40Hz to 30.000Hz .

"Low-pass" frequency control

This control is active when the switch is set to "Low-pass" and permits selection of the desired crossover frequency. Example: at a setting of 150Hz , the loudspeaker has a frequency range of 10Hz to 150Hz .

Operating indicator (POWER / PROTECT)

Green lamp: Power amp on, regular operating condition

Red lamp: Power amp has been switched off electronically, due to a fault or failure.
