[. . . ] Installation and connection instructions The battery's negative terminal must be disconnected for the entire time it takes to install and connect the device. You must observe the vehicle manufacturer's safety notices (airbags, alarm systems, trip computers, immobilizers) regarding this. The Blaupunkt power amplifier must be professionally secured in position for reasons of safety in the event of an accident. The surface to which it is attached must be suitable for the screws that are included and must provide a secure hold. [. . . ] Use loudspeakers with an impedance of 2-4 . Observe the maximum load rating (music power rating). use loudspeaker connecting cables up to 4 mm2. Do not connect loudspeakers to earth ­ only use the correct terminals as indicated. The cross section of the positive and negative cables must be at least 6 mm2. The positive cable between the battery and the amplifier must be protected directly at the battery using a fuse holder (TSA 280: 30 amperes / TSA 2120: 50 amperes). Undo the cover's screw (A) that is located above the switches and controls. Afterwards, lift the cover and carefully remove it. Undo the six screws (C) that secure the underside of the housing and then take the amplifier out of the bottom half of the housing shell. Class D 2/1 Channel Amplifier TSA 280 / TSA 2120 The amplifier is suitable for connection to car radios that are equipped with RCA connections. If you want to connect it to car radios that are equipped with an ISO connection, please use the Blaupunkt ISO-RCA adapter. If HP is selected, you can use the associated crossover frequency control to adjust the lower cut-off frequency to between 50 Hz and 250 Hz. If you want to precisely optimise the acoustic settings of the crossover, we recommend you obtain advice from a Blaupunkt dealer. It is very important that you take into account the specifications of the loudspeakers being used whilst you are adjusting the crossover. Crossover frequency control (LP FREQ + HP FREQ) If the crossover is activated (LP or HP) by adjusting the position of the X-OVER switch, you can then use the corresponding control to adjust the crossover frequency of the respective filter to anywhere between 50 Hz and 250 Hz (i. Settings for a subwoofer In order to obtain the best sound when a subwoofer is connected, the subwoofer must be separated as far as the frequencies it receives are concerned, i. It must only be fed with low frequencies (bass). Firstly, turn down the GAIN control on the amplifier to minimum and set the LP frequency control to its centre position. Now play some music on your car sound system that you are very familiar with and that contains some low bass (e. Now slowly increase the volume of the subwoofer by turning the GAIN control on the amplifier in a clockwise direction until you feel that the sound of the music is well balanced, i. The bass is neither too weak nor overpowering. Now listen to the relationship between deep male voices and the upper bass and also take note of the relationship between the upper bass (kick bass) and the lower bass. [. . . ] If male voices seem to billow out or the low bass is too weak, you should turn the LP frequency control slightly towards minimum and then continue making your adjustments as described in point 2 onwards. If the bass sounds deep but dirty and booming or the male voices sound too weak, you should turn the LP frequency control slightly towards maximum. Next, continue making your adjustments as described in point 2 onwards. If you want to precisely optimise the acoustic settings of the crossover, we recommend you obtain advice from a Blaupunkt dealer. [. . . ]
