GVS7118 Loudspeaker power amplifier

GVS7118 Loudspeaker power amplifier specially for experiment with 60 W power output can be used with GVS7116C Automatic Oscillation Sweeper. It is featured by easy to simple operation and easy-to-use. GVS7118 has triple protection functions: in case of overload, overvoltage, or short circuit, this instrument will automatically shut off the output to protect from damage; the sine wave distortion is usually less than 0.1%.

Product advantages

  • The signal distortion is small (0.1%), which is much better than general test power amplifiers.

  • This machine has protections from overload and short circuit. Even if the output terminal is short-circuited for a long time, it will not be damaged.

  • The output voltage can be adjusted by the knob on the panel and displayed intuitively.

  • Multiple units can be connected in series to form a power test bench with 8121C and 7116C. Power experiments can be performed on multiple speakers simultaneously, and their operation are easy.
