@HealthyTrade Welcome to HP Community!

 

I understand that you would like to know the 3.5mm Output Frequency Response.

 

 

Line In

 

The Line-In jack supports line-level stereo inputs from laptops, MP3 players, camcorders, etc. It also supports electret type microphones that are commonly used in headsets and lapel microphones. Electret microphones require a DC bias that the jack provides.

 

Connector

3.5mm stereo jack

Format

Unbalanced
Left Channel - Tip
Right Channel - Ring

Full Scale Input

+4dBu = 1.23V rms = 3.47V p-p
-16dBV = 0.158V rms = 0.448V p-p
-31dBV = 0.0292V rms = 0.0797V p-p

Frequency Response

20Hz - 20KHz

DC Bias Voltage

5V

DC Bias Impedance

3.1K

AC Input Impedance

2K

 

Line Out

 

The Line Out jack supports connecting to powered speakers, recording with devices such as laptops or tape recorders, and can also drive headphones and headsets. The output does not deliver enough power to connect to a speaker directly.

 

Connector

3.5mm stereo jack

Format

Unbalance
Left Channel - Tip
Right Channel - Ring

Full Scale Output

+4dBu = +1.2dBV = 1.14V RMS = 3.25V p-p

Frequency Response
RL = 10K

20Hz - 20KHz

Source Impedance

50 ohms

Minimum Headphone Impedance

32 ohms
