The Yamaha NE-1 is a portable parametric equalizer powered by a 9V battery. It features controls for frequency, Q (quality), and level to shape audio signals. The unit includes an input jack for instruments like bass guitars and an output jack for amplifiers or mixers.
Key operational details include selecting between SHALLOW, DEEP, or FLAT equalizer curves using the Q control. Users must ensure the instrument is disconnected from the amplifier before plugging into the NE-1's INPUT jack to prevent damage. The manual also covers battery replacement procedures and maintenance precautions.
| Frequency Range (SHALLOW) | 150 Hz — 6 kHz |
|---|---|
| Power Source | S-OO6P (6F22) 9V battery x 1 |
The unit requires an S-OO6P (6F22) 9V battery, which is sold separately.
Use the Q Control to select SHALLOW for a smoother curve, DEEP for a sharper curve, or FLAT for all frequencies.
Make sure you turn down the volume on the amplifier connected to the OUTPUT jack.
