Front Panel:
1.) Channel Select
-
Selects between the solid state pre-amp and the tube pre-amp. The footswitch, when connected, overrides the front panel
switch.
2.) Solid State Voice - This control is an overall tone shaping control for the solid state pre-amp. It works in conjunction with the equalizer
section.
3.) Solid State Gain - This is the volume control for the solid state pre-amp. It varies the input level of that channel. This will produce the
cleanest possible signal.
4.) Tube Voice - As with the previous voice control, this control is an overall tone shaping control for the tube pre-amp. It also works in
conjunction with the equalizer section.
5.) Tube Gain - This is the volume control for the tube pre-amp section. It varies the input level of that channel.
This can be used to add a
warmer sound to the signal all the way to adding a bit of edgy sounding distortion.
6.) Compressor Ratio - Compression “levels out” a signal’s peaks. It smoothes out the sound making notes sound evenly played. This control
adjusts the amount of compression applied to the signal. In the counterclockwise position there is very little. As you increase this control, it
flattens out the signal making the sound “squashed” or very squeezed. The control range is from 1 to 1 compression to 5 to 1.
7.) Compressor Threshold - This control sets the point where the compressor is actually engaged. This is a “soft knee” compressor that
gradually compresses the sound. Increase the control and compression becomes more apparent.
8.) Chorus Depth - This control mixes the dry sound with the chorus effect. The amount of desired chorus effect will range from very subtle
to very noticeable. The effect is controlled via the footswitch either on or off
9.) Chorus Rate - This control determines how fast the chorus effect cycles around the sound. Slower speeds will make the sound shimmer
and sound silky to a fast speed that sounds like a warble or wavering sound. The ranges are from
.05
Hz to 7 Hz.
10.) Input 1 - This %” jack accepts signals from all normal basses and instruments.
11.) Input 2 -
This %” jack is padded down -8 db and will accept signals from active basses, keyboards or line level signals that have already
been pre-amplified.
Equalizer Section - The TRB400H uses Active Electronics to give you an entire range of tonal control. Active equalizers allow adding or
subtracting frequencies at a given range. Standard tone controls only give you the ability to subtract on a wide range level. These selections
were specially selected for the bass guitar frequency ranges..

E.Q. - This control is centered at 100 Hz. It gives you +/- 15 db of gain.
E.Q. - This control is centered at 250 Hz. It gives you +/- 15 db of gain.
E.Q. - This control is centered at 650 Hz. It gives you +/- 15 db of gain.
E.Q. - This control is centered at 1500 Hz. It gives you +/- 15 db of gain.
E.Q. - This control is centered at 3000 Hz. It gives you +/- 15 db of gain.
6000
Hz E.Q. - This control is centered at 6000 Hz. It gives you +/- 15 db of gain.
19.) Master Volume - This is the overall volume control for the entire amplifier. It works in conjunction with the pre-amp volume controls.
For the cleanest signal possible
,it
is recommended that you set your master volume control half to three quarters of the way open and then
start increasing the individual pre-amp controls. If you prefer a slightly dirtier sound, open the pre-amp volumes up more and decrease the
master volume control until the proper ratio is achieved.
20.)
Power On/Off - This pushbutton turns the amplifier on or off.
21.) Blue Jewel Light - This lamp is activated when the unit is powered up.
Back Panel:
-
1.) Fuse Holder
This holds the fuse. The fuse is a 4 amp 250V AGC type fuse. Replace with ONLY the same type.
You should always carry a couple of spare fuses just in case you need them. Caution: if the fuse blows repeatedly,
contact your local dealer or service center for repair.
2.) Power Cord
TRB400H
is equipped with a 3 prong. Grounded type A.C. supply cord designed to reduce
-
The
the possibility of shock due to electrical fault. Be sure to connect to a grounded receptacle. DO NOT alter the plug!
-
3.) 8 Ohm Speaker Output
This %” jack is for hooking up a single 8 ohm speaker cabinet or a single 4 ohm cabinet.
Do not go below a 4 ohm load. All the TR Series cabinets are 8 ohms.
-
4.) 8 Ohm Speaker Output
This %” jack is provided for hooking up an additional 8 ohm speaker cabinet. Do not
go below a 4 ohm load.
-
5.) Full Range Output
This is a balanced low impedance 3 conductor (TRS) %” jack which can also serve as a
direct output to additional amplifiers, mixing consoles or recording equipment. This jack provides the entire range
output.
-
6.) Low Output
This is a balanced low impedance 3 conductor (TRS) %” jack which provides the low frequency
output to hook up additional amplifiers when bi-amping. The point where the frequencies are split and the low
frequencies are fed to this jack. It is determined by the crossover frequency control.
-
7.) High Output
This is a balanced low impedance 3 conductor (TRS) %” jack which provides the high frequency
output to hook up additional amplifiers when bi-amping. The point where the frequencies are split and the high
frequencies are fed to this jack. It is determined by the crossover frequency control.
1/4"
Wiring for
3 conductor low impedance connectors - Tip is positive and corresponds to pin 2 on a XLR connector.
Ring is negative and corresponds to pin 3 on an XLR and Sleeve is ground and corresponds to pin 1 on the XLR.
-
8.) High Level
for additional amplifiers. This control range is from an attenuated -12 db to a boosted
9.) Crossover Frequency
This is the volume control for the signals coming from the high output jack. It controls the volume
+6
db.
-
This control determines at what actual frequency the signal is divided between the two
appropriate outputs. It is variable from 125Hz to 2 KHz.
-
10.) Pre-Amp Output
This is an unbalanced 2 conductor (TS) %” jack which sends the signal to the inputs of
external processing equipment such as equalizers, delays or other outboard gear. This jack is post equalizer and post
master volume control.
-
11.) Pre-Amp Input
This is an unbalanced 2 conductor (TS) %” jack which returns the signal from the outputs of
external processing equipment such as equalizers, delays or other outboard gear. This jack is post equalizer and post
master volume control, therefore the volume control on the external processor becomes your overall master volume.
-
12.) Footswitch Jack #1
This is a 3 conductor (TRS) %” jack which hookup to the supplied footswitch. It controls
the chorus on/off and pre-amp channel selection. Tip is channel select and Ring is Chorus on/off.
13.) Footswitch Jack
This is a 3 conductor (TRS)
1/4”
jack which hookup to the supplied footswitch. It controls
#2 -
the compressor on/off and the equalizer on/off. Tip is compressor and ring is the equalizer.
