Turning it clockwise with a crossscrewdriver can increase the gain, and vice versa can reduce the gain,the adjustable range of gain is 15dB-25dB. Sunhans 868MHz/915MHz booster default gain is 23dB. BulletPoint5 : 【Package contents】 1X SH09Gi1000 LoRa Amplifier;1X Power adapter;1XColor Box BulletPoint6 : Please note this is a preamplifier (not like NS-08E), which needs to be connected with amplifiers or active speakers. It suits for almost all amplifiers in the market especially for our tube headphone amps like our Nobsound NS-08E, NS-01E and NS-02E, and will greatly enhance the sound performance of digital amplifiers like our TPA3116 amps.

A true FET input stage is incorporated to provide superior sound quality and speed for exceptional audio performance. This, in combination with high output drive capability and excellent DC performance, allows for use in a wide variety of demanding applications. In addition, the OPA134 has a wide output swing, to within 1 V of the rails, allowing increased headroom and making it ideal for use in any audio circuit.The OPA2134 SoundPlus audio operational amplifiers are easy to use and free from phase-inversion and the overload problems often found in common FET-input operational amplifiers. They can be operated from u00b12.5-V to u00b118-V power supplies. Input cascode circuitry provides excellent common-mode rejection and maintains low input bias current over its wide input voltage range, minimizing distortion. OPA2134 series operational amplifiers are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions, including high load capacitance. The dual and quad versions feature completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded.
