This switch turns the power for the built-in SRT POW-
ERED preamplifier on and off.
Power Switch and LINE OUT Jack Status Correspondence Table
• This product is designed so that the power can be turned
on only when a plug (cable) is inserted into the LINE OUT
jack. When a plug is not inserted into the LINE OUT jack,
the power will remain off regardless of the position of the
power switch.
• If the power switch is off while a plug (cable) is inserted
into the LINE OUT jack, the Piezo Pickup signal will be
directly output to the LINE OUT jack (passive output).
Passive output is used in emergency situations when
there are no batteries, or when using sound reproduction
on an external device, such as a preamplifier.
• Since the power is turned off during passive output, the
SRT POWERED preamplifier will not operate. Except for
the power switch, the knobs on the control panel will all be
disabled.

Setup
Tuning
The SILENT Bass
TM
is shipped from the factory with the bridge in place and the strings
slightly loosened. The bridge’s height is set to an average person’s height. Since the posi-
tion of the bridge will sometimes shift during transport, make sure to properly adjust the
position of the bridge before tuning the strings.
• The lower side of the bridge supports the 1st string
(G), the higher side supports the 4th string (E). When
looking at the bridge from the side, the surface that
has a sharper curve should face the fingerboard (fac-
ing up when in the playing position). (Fig. 1)
• The correct position for the bridge is where the surface
of the bridge facing the tailpiece is at a right angle to
the body surface on which the bridge rests. [Fig. 2]
Position the bridge so that its legs do not come in con-
tact with the escutcheon (the plastic part).
Adjustments If the Bridge Is Leaning
• After tuning, check that the surface of the bridge fac-
ing the tailpiece is vertical to the body surface on
which the bridge rests. If it is leaning to one side,
slightly loosen the strings and then use both hands to
raise the bridge.
• If, after tuning, the tailpiece is leaning to one side
when seen from the front, slightly loosen all the
strings and manually straighten the tailpiece. After
that, increase the tension of all the strings as evenly
as possible and then re-perform tuning.

• The height of the bridge for the SILENT Bass
TM
can be
adjusted. Turn the metal adjusters clockwise to lower
the bridge, and counter-clockwise to raise it. [Fig. 3]
• The strings are tuned to the following pitches. The 1st
string is tuned to G, the 2nd string to D, the 3rd string
to A, and the 4th string to E. Use a piano, tuning fork,
tuner, etc., and adjust the pitch of each string using the
tuning pegs.
Tuning machine tension adjustment
The tuning machine tension regulates the amount of pressure
required to turn the tuners and can be adjusted using the sup-
plied Allen wrench.
• If the tuning machine turns with very slight pressure
Rotate the adjustment screw to the right (clockwise: A).
• If the tension is tight and the tuning machine is hard
to turn
Rotate the adjustment screw to the left (counter-clock-
wise: B).
• Before adjusting the bridge height, loosen the strings in order to relieve pressure on the adjusters and
make it easier to rotate the adjusters. Rotating the adjusters with without reducing string tension can
result in damage to the bridge or strings, etc.
• When adjusting the bridge height, make sure that the height of both legs is kept the same. Increasing
string tension on legs that are unequal in height can result in poor surface contact of the bridge’s feet,
causing inferior sound quality, noise, damage to the bridge, etc. (Fig. 3 *3).

plied mute onto the strings as shown in the illustration below.
• To prevent the battery from being depleted, be sure to turn the power switch off after finish-
ing use. Also, remove the cable.
• You can use this product even without batteries by turning the power switch off (to passive
output) and connecting the product to an external device that supports passive output.
When using an external device, connect a device (DI, etc.) that has input impedance of 10
MΩ or higher. Sufficient output and frequency characteristics may not be ensured if the
input impedance of the connected device is lower than the specified value.
• To prevent faults in this product or the external device as well as noise, be careful regarding the
order in which you turn the power switch on or off and make connections.
Order for Turning the Power Switch Off and Making Connections (Example)
1. Lower the level of the channel to which this product is connected on the output device, such as a PA.
2. Turn off the power switch of this product.
3. Disconnect this product and the output device, such as a PA.

ing sure it fits into its corresponding groove at the bottom of the tailpiece. Pull the string up and
over the bridge.
• Do not remove all strings at the same time. Make sure to change the strings one at a time.
NOTICE
• The ends of the strings are sharp and can cut fingers. Use caution when
changing strings.
• When changing or adjusting strings, do not put your face close to the instru-
ment. The string may suddenly break resulting in eye injury or other acci-

3. Insert the end of the string into the hole on the peg, turn the peg and make one or two wraps to
one side of the hole as shown in the illustration below, and then make the remaining wraps in
the opposite direction. From the perspective at the front of the instrument, the first couple of
wraps on the 1st (G) and 2nd (D) strings should be to the left of the hole, whereas on the 3rd
(A) and 4th (E) strings, the first wraps should be made to the right.
4. Turn the pegs to perform tuning to match the sound of a piano, tuning fork, tuner, or the like.
For more information about tuning, see the cautionary notes under “Tuning” (page 12).
• Before winding the strings, stand the bridge so that the surface of the bridge facing the tailpiece is
vertical to the body surface on which the bridge rests.
• Before winding the strings, make sure that each string is positioned in its corresponding groove on
the bridge.
• Before winding the strings, the adjust string length so that the string does not rub up against the
pegbox wall. Performing tuning while a string is rubbing up against the wall can result in a broken
string or the like.
• When winding strings, be careful that the bridge is not pulled by the strings and pushed down
towards the fingerboard.
• When not using the instrument for a long period of time, slightly loosen the strings before storage.
• Always use the product with the bridge standing vertical to the surface on which the bridge rests. Using
the product with the bridge leaning to one side can shorten the service life of the bridge and reduce
sound quality.
