■ Names and Functions
Thank you for purchasing the YAMAHA NE-1 Parametric Equalizer.
Please read this manual thoroughly and keep it in a safe place for future
■ Precautions
◆ To prevent damage, do not use the NE-1 in the following locations:
• places where the unit will be in direct sunlight;
• places subject to temperature and humidity extremes;
• places that are sandy or dusty.
◆ To power the NE-1, use only a single 9V (6F22) battery.
◆ For maximum battery life, always be sure the instrument is
disconnected (power off) from the NE-1’s INPUT jack when not in
◆ If an exhausted battery is left in the unit for an extended period of
time, it may leak and cause malfunctioning of the unit. When the
battery becomes exhausted, always remove it and replace it as soon
as possible.
◆ Do not subject the NE-1 to strong physical shock or vibration. Do not
use excessive force on any of the controls.
◆ Never use solvents such as benzene or thinner to clean the NE-1.
Wipe clean with a soft, dry cloth.
◆ After reading the owner's manual, keep it in a safe place for future
◆ After tuning is complete, always remove the contact mic from the
instrument. Leaving the mic in place for extended periods of time will
damage the instruments lacquer finish.
q Input Jack (INPUT)
The input jack for the main unit. Connect the output of a bass guitar to this
jack. The main unit’s power will be switched ON when a plug is inserted
into this jack.
* Before connecting or disconnecting the plug, make sure you turn
down the volume on the amplifier, etc. that is connected to the
OUTPUT jack e.
w Power Indicator
When the Power is ON, the indicator will light.
e Output Jack (OUTPUT)
The output jack for the main unit. Connect this jack to a bass amplifier,
mixer, etc.
r Level Control (LEVEL)
This is used to control the output level of the main unit.
t Q Control (Q)
This is used to select the equalizer’s variable curve.
SHALLOW: Provides a smoother curve.
DEEP: Provides a sharper curve.
FLAT: All frequencies will be flat.
y Frequency Control (FREQUENCY)
Never dispose of used batteries by burning them.
Also make sure to keep batteries away from children.
■ Using batteries
This is used to set the equalizer’s center frequency.
* Turning the knob when FLAT is selected with the Q Control will
produce no effect.
The NE-1 is not supplied with a battery. Before using, please purchase
an S-006P (6F22) 9V battery (we recommend the use of alkaline batteries) and set it using the following procedure.
Also, when battery power is low, the power indicator will be weak and
the sound may have noise or distortion. To prevent possible damage to
the unit due to battery leakage, etc., remove the battery when power is
depleted. Please replace the battery as soon as possible.
● Procedure
1. Use a coin, etc., to loosen the fixing screw and open and remove
the battery compartment cover located on the bottom of the unit.
2. Remove the old battery and replace it with a new battery (S006P:6F22, 9V battery) taking note of the polarity.
3. Replace the battery compartment cover and tighten the fixing screw.
“DEEP-4” is Nathan’s Favorite Setting.
