EFFECTS BLEND
This control blends the signal sent from your bass with that coming from your effects unit. With the Effects
Blend control fully counter-clockwise, no signal from your effects will be heard (“dr y”). As you turn this control
clockwise, more of the effect can be heard in the overall sound. When the Blend control is fully clockwise
(“wet”), no true or unaffected signal is heard other than what your effects unit provides. If your effects unit
has a similar control, adjust it to the fully “wet” position. This will avoid any possible phasing problems.
The Blend circuit is similar to that used on recording consoles with the effects loop on a “side chain” to the
normal circuit. Unless the control is set to the full “wet” position, you will always get the full sound of your
instrument AND get the diversity an effects unit offers. This circuit is also effective in reducing noise generat-
ed by effects units because it is located after the gain stages in the preamp.
The Effects Blend functions
only when the effects loop is being used
. It is activated when a 1/4" phone plug
is inser ted into the Effects Receive jack. See the “Effects Loop” section for more information.
LIMITER CONTROL
This Limiter circuit is located after (post) the Master Volume and before (pre) the power amplifier. Therefore, the
Limiter is driven by the Master Volume. Its threshold (or starting point) is set by the Limiter control and can be
used to achieve maximum overall apparent volume without unduly overdriving the power amplifier or internal
speakers. Turning the Limiter control clockwise (toward “max”) increases the effect of the Limiter circuit.
LIMITER ACTIVE LED
When the threshold of the Limiter circuit is reached, the green Limiter Active LED will light. This LED will be
inactive when the Limiter is set to the “off” position or when playing at lower levels.
MASTER VOLUME
The Master Volume adjusts the level being sent to the power amplifier section of the Bass 750 and controls
the overall volume of the unit. It DOES NOT affect the level of the record XLR output in the “line” position.
Losses caused by effects units can be recovered by increasing the Master Volume.
SPEAKER ON/OFF SWITCH
Moving the Speaker On/Off Switch to the “On” position allows the signal from the amplifier to be heard
through any speaker enclosure(s) connected to the Bass 750’s output section. Moving the Speaker On/Off
Switch to the “OFF” position disables the Bass 750’s output section. This feature allows the user to:
1. Use the XLR Output without using the internal speakers. This is especially useful in recording when
you are not miking the speakers and only a direct signal is required.
2. Tune up without inter fering with other band members while using the Tuner Send feature.
Note:
If you do not hear any sound when you plug in and your system is properly connected, check the
position of this switch!
POWER ON/OFF SWITCH
Moving the Power Switch to the “On” position will turn on the amplifier as indicated by the Power LED lighting
(directly above the switch).
REAR PANEL FEATURES
AC OR MAINS FUSE
This fuse is provided to protect the internal electronics against power surges, etc. It also protects the unit
against itself should one of the internal components fail. If this fuse should open, replace it with the same
type of fuse and rating.
Note:
Do note defeat the purpose of this feature by using a fuse of a higher value. It could damage the
unit and will void your warranty!
