Feedback Control: In situations where restrictions make a feedback proof setup impossible, Yamaha graphic equalizers can be used to reduce the gain of problem frequencies, thus minimizing the possibility of sudden outburst of feedback that can ruin a performance.
Sound Shaping : Yamaha graphic equalizers are also creative tools that can shape the tone of an instrument or voice to achieve a better blend in the mix. When added to reverb, EQ can electronically simulate a wide range of acoustic environments.
Noise Suppression: Graphic equalization can effectively minimize tape hiss, stage rumble, wind noise, microphone popping, excessive sibilance, and other sources of unwanted noise.
response: 20 Hz - 20 kHz, +/- 0.5dB @ +4dB* 600 ohms
Input Impedance: 15k ohms
Output Impedance: 150 Ohms
Indicators: Green LED on each channel turns
on when EQ is on. Red LED on each channel turns on when post-EQ signal reaches the level 3
dB below clipping. Green LED on each channel turns on when post-EQ signal reaches the
level 13 dB below nominal level.
