Risk of electrical shock.

• Connect the device only to a properly wired and earthed electrical wall
socket providing the mains voltage indicated on the rear panel.

• NEVER operate the device if the power plug or the power cord is damaged.

cloth. Liquid getting into the amp will risk a short circuit and will be
hazardous.

• NEVER expose the device to direct precipitation or moisture and never use it
in a damp or wet environment.

• Ensure that the power cord does not become wet during operation.

• Do not subject the amp to high temperatures, direct sunlight, severe
vibrations, shocks or tremors, or excessive dust.

• Notice regarding power disconnection
To completely disconnect the device from the mains power source the power
plug must be removed from the power socket. For this reason the device

must 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

immediately 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 going to be used.

• 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
circuit or an electrical shock. Do not place the device, speaker cabinets or

anything 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.

• Never manipulate the power cord of the plug. If a power cord is provided
with an earth lead, this is mandatory to ensure safe operation!

 Riskofre!

• NEVER leave the device unattended while it is switched on.

• Never cover 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 cable and device away from children. Children frequently

underestimate 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.

• Important! Keep sufcient distance from the device when operated
with high volume level. Listening to music with high sound pressure
level may cause permanent damage to your hearing!

 Riskofdamage!

• Valve amps like GA 15 must never be operated without a proper speaker
load. The actual impedance of the connected speaker load must exactly
match the chosen speaker out socket (4, 8, or 16 ohm). Otherwise the
amplier will be seriously damaged.
