2. Safety Instructions
For your own safety you should read this section in full rst!
Risk of electrical shock.
Connect the device only to an electrical wall socket providing a mains volt-•
age of 220-230 V / 50 Hz.
NEVER operate the device if the power plug or power the cord is damaged.•
NEVER submerse the device in water. Wipe it only with a slightly damp cloth.•
NEVER expose the device to rain or moisture and never use it in a damp or wet•
environment.
Ensure that the power cord does not become wet during operation.•
You must NEVER open the housing of the device or try to repair it. There are•
no user serviceable parts inside. Warranty will become void if you open the
housing.
Do not place objects containing uids, e.g. ower vases or beer bottles, on •
or near the device.
Notice regarding power disconnection•
To completely disconnect the device from the power source the power plug
must be removed from the power socket. For this reason the device should
be placed in a position where a constant unobstructed access to the power
socket is assured, thus in an emergency situation you are able to immediate-
ly pull out the power plug. To eliminate the risk of re you should completely
disconnect the power plug from the power socket when the device is not go-
ing to be used for a long time, for example, during holidays.
Always grasp the power cord by the plug. Do not pull on the cord itself and•
never touch the power cord with wet hands as this could result in a short cir-

cuit or an electrical shock. Do not place the device, speaker cabinets or any-
thing else on the power cord and make sure that it does not become clamped.
Place the power cord in a position where it can not be trod on. A damaged
power cord can cause a re or an electrical shock. Check the power cord from
time to time. Should it become damaged contact our customer service centre
to have it replaced.
 Riskofre!
NEVER leave the device unattended while it is switched on.•
Never cover the fan or the ventilation slots of the device while it is switched•
on. Avoid placing this device in locations that provide insufcient ventilation or
hot locations and do not place the device in direct sunlight or under strong
articial light sources. Otherwise, it may overheat and become irreparably
damaged.
Do not place any open sources of re, like candles, on the device.•
When a thunderstorm with the risk of lightening threatens please disconnect•
the device from the mains power.
 Riskofpersonalinjury!
Keep the power cord and device away from children. Children frequently un-•
derestimate the dangers of electrical equipment.
Ensure a safe location for the device.•
Do not operate the device if it has sustained a fall or is damaged. Arrange for•
the device to be checked and/or repaired by qualied technicians.
WARNING:
This symbol, wherever it appears, alerts you to the presence of
uninsulated dangerous voltage inside the enclosure--voltage that
may be sufcient to constitute risk of shock.
This symbol, wherever it appears, alerts you to important operating
and maintenance instructions in the accompanying literature. Read
the manual.

ON / OFF mains switch
GROUND LIFT when pressing this button, the signal’s ground is
directly connected to earth. In certain situations
this may reduce hum noise
LINE OUT connect additional power amps here
EFF. SEND if you want to use an external effects device,
connect its input here
EFF. RET to return the processed signal from the effects unit
DI OUT this output provides the frequency corrected line
level signal to feed recording devices or mixing
consoles
valid for HB 115B MK III only:
PRE this switch toggles the point where the DI OUT
signal is tapped. Press the button if you want the
DI OUT to provide the pre-effects signal. Release
the button if you want the DI OUT to provide the
post-effects signal

3. Installation
Mains voltage
Please ensure that your local area’s mains power voltage matches
the mains power specication of your amp as indicated on its rear
panel before you connect the unit to an AC mains power outlet!
Mains connection
Use the enclosed power cable to connect the unit’s MAINS IN to a properly
wired and earthed (!) IEC power socket. The cable meets all of the international
safety certication requirements.
Speaker connection
Use the SPEAKER OUT sockets to connect external speaker cabinets. HB 115B
MK III allows to switch on/off the built-in horn using the HORN OFF switch.
Caution:
Before you connect an external speaker to HB 115B MK III you must
disconnect the internal speaker. Otherwise the overall impedance will drop
below 4 ohms and the amplier will be damaged!
NEVER connect an external speaker or a mono plug to the output jack for the
internal speakers as this output uses a special pin assignment (tip = horn, ring
= woofer sleeve = ground)!
Audio connections
The set is equipped with mono phone jacks, except for the headphones output
which is a stereo jack (TRS).
Here you see some useful wiring schematics for the most usual connector
types:
1/4″ stereo TRS jack plug unbalanced use of mono 1/4″ plug.

Using headphones
You can connect headphones to your bass amp with a 1/4” TRS jackplug (not
supplied). When you have connected the headphones, the loudspeakers are
disconnected and you will only hear sound via the headphones.
Important! Listening to music with headphones for long periods
and at high volume levels can lead to permanent hearing
damage!
Evenwhenusingtheamplierwithoutheadphonesyoushoulddriveit
onlywithlowvolumeoruseproperearprotection!
