1. DIRECT OUT connector
This is a direct out connector for connection to your re-
corder or PA system. The polarity is as shown in the dia-
gram.
2. POST EQ switch
This selects the point within the preamp circuit from which the Direct Out signal
will be taken. With the “PRE” setting, the signal is taken directly from the input,
and the amp controls will not affect the sound in any way. With the “POST” set-
ting, the signal is taken from after the effect return, so that all controls other than
“VOLUME” will affect the signal. Regardless of this setting, the signal from the
CD input is never sent from DIRECT OUT.
3. GND LIFT switch
The setting of this switch specifies whether pin 1 of the direct out connector will
be connected to the electrical ground of the SW100 itself. If your equipment is
connected in a complex way and a ground loop is causing hum, using this switch
to disconnect the ground will reduce the hum.
4. INPUT jack
This is a 1/4" phone jack input. Use a shielded guitar cable to connect your elec-
tric bass guitar to this jack.
5. SENSITIVITY switch
This switches the input sensitivity by 5 dB. Use the “HIGH” setting if your bass
has passive pickups, or the “LOW” setting if your bass has active pickups.
6. PRE AMP CLIP indicator
This indicator will light blue if the preamp, GAIN, and equalizer settings cause
the limiter circuit to operate before the “VOLUME” control.
7. GAIN control
This controls the gain of the preamp. Raising the level will increase the volume,
but after you pass a certain level, a limiter will operate to prevent distortion, and
the level will not increase very much. If you continue raising this control, the
limiter will apply more strongly, producing an effect as though the threshold were
lowered. Adjust this control in conjunction with the EQ and the VOLUME control
to get the sound you want.
8. BASS control
This is a shelving-type equalizer for the low frequencies. It boosts or cuts the
level of the 100 Hz region in a range of
±
15 dB.
9. MIDDLE control
This is the mid-frequency equalizer. It lets you apply up to
±
15 dB of boost or cut
to the region selected by the SELECT switch.
10. SELECT switch
This switches the frequency at which the MIDDLE control will apply boost or cut.
You can choose either 250 Hz, 500 Hz, or 800 Hz as the frequency.
11. TREBLE control
This is a shelving-type equalizer for the high frequencies. It boosts or cuts the
level of the region at 4 kHz and above in a range of
±
15 dB.
12. PRESENCE control
This is the ultra-high frequency equalizer. It boosts or cuts the level of the 7.4 kHz
region in a range of
±
15 dB.
13. FX MIX control
This controls the proportion at which the external effect sound and the direct
sound are mixed. With the EVEN setting, equal amounts of the two are heard.
When turned all the way to DRY, only the direct sound is heard. When turned all
the way to WET, only the effect sound is heard. This control is active only if an
external device is connected to the rear panel EFFECTS RETURN jack.
14. VOLUME control
This adjusts the output level of the amp. Simultaneously, it also controls the out-
put level of the CD INPUT.
15. CD INPUT jack
These are stereo phono input jacks that can be connected to a portable CD/MD/
cassette player or to the headphone output of your stereo system. Use the VOL-
UME control to adjust the volume.
16. LINE OUT jack
This is an output jack with an output level of approximately 0 dBm. You can
connect it to an external mixing console or similar equipment.
17. HEADPHONES jack
This is a 1/4" output jack for stereo headphones. The sound is not reproduced
through the built-in speakers when headphones are in use.
Warning The headphone output is capable of producing high volume lev-
els. When using headphones, turn down the VOLUME, and then
gradually raise it to adjust the volume. The noise and distorted
audio that is produced when the plug is inserted or disconnected
at a high volume setting will not only damage your headphones,
but may also damage your hearing.
18. TWEETER switch
This switches the built-in tweeter on/off.
19. POWER switch
This switch turns the power on/off. When you are not using the amp, please
leave it turned off.
