First of all, we would like to congratulate you on choosing the BLACK HYDRA car audio amplifier!
On these pages, you will not find an absolutely accurate justification for the superiority/uniqueness of our audio systems, because music can only be assessed by emotions gained from listening. Black Hydra audio systems will satisfy you by the excellent sound quality rather than with the numbers. It will give you true emotions of the listening to your favorite music, incomparable with the evaluation of «dry» specifications written on paper in silence.
During building of audio system based on Black Hydra components we recommend that you use only high quality components in each of its links, to achieve the most accurate transmission of music material. Remember the quality of any system is determined by its weakest link.
Technical specifications of Black Hydra amplifiers are equal and correspond to the most of best industry representatives, while at the same time surpassing them in subjective estimations of sound quality.
Perfectly honed circuit solutions with excellent architecture, combined with the use of components of the highest grade, made it possible to make our product unique, capable of transmitting the finest nuances of the sound of your favorite compositions without distortions and with high details.
The power supplies of all amplifier models are designed with an impressive reserve, which allows achieving maximum output even at the upper limits of the declared power level.
By placing individual parts of the circuit on subboards the lengths of the conductors were reduced and optimized, which completely eliminated interference between channels and as a result improved crosstalk attenuation, making it possible to achieve greater clarity of images in the sound stage.
JUST ENJOY

Black Hydra car amplifiers are designed to operate in 12-volt systems with a permissible voltage of 10-17V. A significant voltage deviation from operating limits can lead to incorrect operation of the device or to its complete failure.
We recommend the use power cables made of oxygen-free copper, with properly selected diameter that allows the transmission of an electrical signal with minimal loss. If the distance from the battery to the amplifier exceeds 4m, we recommend using larger diameter cables to prevent loss of sound quality.
Start power supply wiring by connecting the power cable to the negative polarity (minus), grounding it at the nearest point to the amplifier at the car body. Connect the positive power cable directly from the corresponding battery terminal.
To avoid problems in the electrical and electronic systems of your car, the installation and connection of the power supply to the amplifier should be carried out only by qualified personal! (Fig.1)

Amplifier has 2 pcs of blade type protection fuse 35 A. In case you need to replace the fuse, use only the same type and value as the original. (Fig. 2)
The amplifier supports two methods of remote activation:
To select desired turn on method please use power on switch at the amplifier's side panel.

- By high level signal input (HIGH): by connecting the high level output signal of an OEM source to the high level input terminals of the amplifier and setting the POWER ON SW switch to HIGH. In this way the auto turn on function is activated to turn on the amplifier when high level signal is present. By setting the POWER ON SW switch to ACC, this function is disabled.

- By remote input (ACC): by connecting the remote input terminal ACC with a remote out signal coming from an aftermarket head unit that will enable the amplifier turn on and off function.

You can also use remote output terminal REM OUT to automatically turn on second amplifier in your audio system.
BLUETOOTH CONNECTION
Amplifier has built in Bluetooth 5.0, module which supports AptXHD high quality sound profile.
To connect your device to amplifier's Bluetooth module navigate to your device Bluetooth settings and search for Bluetooth device named BETA8. 70 DSP then pair your device with amplifier's Bluetooth. After successful pairing BT LED at the amplifier's side panel will light up blue.

USB-AUDIO CONNECTION FOR ANDROID OS AND WINDOWS PC DEVICES
