Description of ๐Ÿ”Š Enhance Audio Experience with Mini Stereo Line Level Booster Amplifier Preamp - 20dB Gain & Volume Control

Mutiple input/output interfaces: with 3.5mm AUX/stereo RCA/5-DIN inputs and stereo RCA/5-DIN outputs, can be compatible with most low-volume audio sources such as ipod, ipad, phone, TV, MP3 player, potable CD player, computer, video game etc. and boost their output to the level needed to drive amplifier or speakers. With built-in amplification and voltage boost circuit: adjustable gain to match better with different audio sources, support DC 5-24V wide input voltage that can share the power supply of amplifiers, while L1 can always work at a high voltage of 26V to provide ยฑ12.5V high output amplitude and max 20dB high gain. Unique design and HiFi clear sound: double-side PCB design, NE5532P op amp with pluggable socket design, convenient to change other op amps to enjoy different sound and bring much DIY fun for audiophiles. High-qaulity sealed potentiometer, with wide frequency bandwidth and excellent dynamic response, the sound is smooth and natural, warm and delicate with ultra-low distortion. Mini size with exquisite appearance, compact and all-metal design for durability and shielding the electronics from electromagnetic interference with noise rejection. Perfect design in size and function, suitable for many scenarios to increase the output level, such as home stereo system, mixer or speaker setup, karaoke, audio recording, party, live stage event etc.

No volume boost for home cinema

This device does not offer volume boost. I used RCA input and RCA headphone output. The output level was the same as the input level even with the device plugged in and the knob turned to maximum. Maybe it would be useful for turning down the volume, but does nothing to turn it up.

Pros
  • Home cinema
Cons
  • Weight

Enough profit. for receiver and amplifier

I have a DAC that converts pulses of light from my TV into an analog electrical signal that I feed to my radio to get acceptable sound quality from my TV. The DAC output was too low; I had to turn the volume up when watching TV and turn it back down when listening to another source. I used this amp to boost the TV audio signal to match the level of other sources, but I had to turn the volume all the way up. The sound quality is acceptable. Everything is better than the sound quality of mostโ€ฆ

Pros
  • Electronics
Cons
  • I won't say anything

My withdrawal issue has been resolved.

Use case: I have a Lumin D2 that I connect symmetrically directly to an active Elac Navis ARF 51. I connect an unbalanced R and L to my Martin Logan Dynamo 1100X subwoofer. Power was low and the subwoofer was barely audible even at full amplification. Review: This helped boost the signal from the Lumin to the subwoofer 100%. It was very easy to connect. I now have complete control over subwoofer volume and the extra boost I need without a dedicated subwoofer output on Lumin. Dislikes: For theโ€ฆ

Pros
  • Home audio
Cons
  • Big and bulky

Perfect for this purpose

Provides the gain and impedance matching needed to connect a line level preamp source to the 1V input of a studio power amp. The device does not add any noticeable noise or hum. to the signal. On the awkward side: - The volume control (actually the gain) has no detents or knobs, so it's difficult to adjust consistently. - You must provide your own power supply. However, it's simple: I charge my Apple iPhone charger with a handy โ…› inch USB power connector. The device is small and light so itโ€ฆ

Pros
  • Receiver and Amplifier
Cons
  • Defective

No Volume Boost - Receivers and Amplifiers

This device had no volume. I used RCA input and RCA headphone output. The output level was the same as the input level even with the device plugged in and the knob turned to maximum. Maybe it would be useful for turning down the volume, but does nothing to turn it up.

Pros
  • Unique Design and Hi-Fi Clear Sound: Double-sided PCB design, NE5532P op amp with detachable connector, convenient to replace other op amp to enjoy different sound and bring great fun to audiophiles. High quality sealed potentiometer with wide range and excellent dynamic response, the sound is smooth and natural, warm and delicate with extremely low distortion.
Cons
  • So far so good
