Tinsea mpa MINI II Audio Interface Microphone Amplifier
DESCRIPTION
The mpa MINI2 comes equipped with a plethora of input and output interfaces, which can be connected to a variety of interfaces of musical instruments and microphones; the accompaniment interface can be connected to a mobile phone, mp3 or CD player; and the output interface can be connected to a mobile phone for live broadcasting and recording purposes. It is very convenient to use since it can be connected to a variety of professional recording sound cards, entertainment K song sound cards, and integrated sound cards. The Line Out interface is one of those that may also be used as a MINI2 failure test interface.
By directly attaching the headset, one can rapidly establish whether or not the device is broken. Power consumption was a consideration from the very beginning of the design process for the mpa MINI 2. All of the original components are of a high grade despite their low power consumption. The real power usage is roughly the same as the MINI mpa standard. DC 5V-9V is the range of the power supply for the mpa MINI 2. You can use the power bank that came with the device or the original voltage adaptor, both of which are convenient for use outside.
Because of the high levels of interference and ripples produced by these power sources, mobile phone chargers and the USB ports on computers should not be used as a source of power. If you use them as a power supply, you will notice a significant decrease in the quality of the sound. It is important to keep in mind that the power amplifier, the amp, and the mic amplifier are all distinct from one another. Because the mic amplifier has such a great magnification, the low-frequency noise is typically highly noticeable to the human ear. Because of this, you shouldn’t use your common sense of amps and power amplifiers to evaluate the speech amplifier. The advantage is directly proportional to the level of clarity it provides.
