Description
A 2.1 amplifier is an audio amplifier designed to power a 2.1 channel sound system. This type of system typically consists of:
- Two stereo speakers (left and right channels, the “2” in 2.1)
- One subwoofer (the “.1” in 2.1, responsible for low-frequency sounds or bass)
The amplifier takes an audio signal and powers the two speakers as well as the subwoofer. The key thing about a 2.1 amplifier is that it usually has three output channels: two for the stereo speakers and one for the subwoofer.
How it works:
- Two channels (stereo) deliver sound to the left and right speakers.
- One channel handles the subwoofer, which often requires a separate output due to its need for more power and a low-pass filter to produce deep bass.
In short, a 2.1 amplifier is a compact solution for systems where you want both full-range sound (for vocals, instruments, etc.) and strong bass (from the subwoofer) but don’t need the complexity or extra channels of a full surround sound system (like 5.1 or 7.1).
VD99-2.1: HYBRID Amplifier for Speakers and Subwoofer All Together
Description:
High power amplifier for two speakers and one subwoofer. It can easily fulfill audio needs of small and large rooms. This amplifier is ideal to drive high power bookshelf or satellite speakers along with a passive subwoofer/car basstube. It has active low pass filter for subwoofer and will cut off vocals and treble from the subwoofer. A front USB port allows easy connectivity for Pen drives. Two RCA connections can be used to connect TV; DVD players. Having karaoke feature; Microphone will work with all other input modes so one can also sing along with the songs being played. Having line out (pre-amp) feature to connect active subwoofers.
- Hybrid configuration – ORIGINAL BEL 3055 transistors for speakers and a pair of 1943 – 5200 MOSFET transistors for subwoofer with pure copper transformer and 2 low speed cooling fans which slowly and efficiently cools not only the transistor heat sink but also the copper transformer without making any noticeable Fan noise.
- Support for 2 Bookshelf Speakers, 2 Satellite Speakers and 1 Center Speaker and 1 single coil subwoofers upto 10 Inches rated upto 150-200 Watts. This is a stereo amplifier and does not give 5.1 surround sound. The rear speakers will get front speaker left and right sound. The center speaker will get both left and right sound. Bass will be reduced in satellite and center speakers.
- Master Volume to control subwoofer and speaker volume together, Separate Gain and Frequency control for subwoofer
- Frequency Response: 10Hz to 20000Hz, Impedance: 4-8 Ohms, Speaker Size: 8 – 10 inches. Woofer Size 8 – 10 Inches 100 Watts per Channel Nominal power for speakers, 100 Watts Nominal Power for Subwoofer 100 Watts, 600 watts peak power total, Dimensions: 33x29x12 CM 5.1 Kg
- Inputs: 2xRCA, Aux, USB, Inbuilt Bluetooth and FM, Karaoke (Sing along feature). Line out through RCA to connect with other audio devices like active subwoofers
