For Little Bear P7 6N5P Headphone Amplifier Tube Preamplifier Headphone Amp For Music Lovers
Design Key Point:
Its main power amplifier circuit is a headphone amplifier, a classic SRPP circuit. Background noise is extremely low and the sound quality is guaranteed. We have only changed power supply part. Now it is powered by a switching power supply, then boosted, filtered, and then supplied to the main power amplifier circuit. The headphone amp is lighter and suitable for users with small desktop space.
Features:
- One 6N5P tube and two 6N3 tubes are used. They can be upgraded to 6080 and 5670 tubes.
- Premium components. Before the output, filter capacitors are all original Japanese capacitors, coupling capacitors are two capacitors for WIMA, and resistors are 1% metal film resistors.
- All aluminum body, equipped with a switching power supply 24V, 4A.
- The main function is current amplification, and the voltage amplification is small. So if you connect a mobile phone as a sound source, you may feel that the sound of this machine has not become much louder. Especially when using lower impedance headphones, this is normal, but its current is sufficient. To clearly distinguish volume changes, use high-impedance headphones, such as headphones above 200Ω, HD600, HD650, and the like. The effect will only come into play when professional player or decoder is connected. Because the output voltage of these players is high enough.
- P7 can drive 30~500Ω headphones.
- Support two output and input methods. Input mode: The default design of the machine is that when the front 3.5mm input is used, the rear RCA input is automatically disconnected. In terms of output: when both the front output ports are connected to headphones, the rear RCA output is automatically disconnected.
Package Included:
- 1 x Set of Headphone Amplifier
Note:
- The headphone amp is assembled.
- There is a small fan for heat dissipation in the machine, and the bottom case will be hotter after long working hours.
- Audio cable is not included, please prepare it by yourself.
