N  THIS  MANUAL  A  LIGHTNING  SYMBOL  WITHIN  A  TRIANGLE  WARNS  YOU  ABOUT  THE 
POTENTIAL FOR DANGEROUS ELECTRICAL SHOCKS – WHICH CAN ALSO OCCUR EVEN AFTER 
THE MACHINE HAS BEEN DISCONNECTED FROM A POWER SOURCE.

AN  EXCLAMATION  MARK  (!)  WITHIN  A  TRIANGLE  IS  INTENDED  TO  MAKE  YOU  AWARE  OF 
IMPORTANT  OPERATIONAL  ADVICE  AND/OR  WARNINGS  THAT  MUST  BE  FOLLOWED.  BE 
ESPECIALLY ATTENTIVE TO THESE AND ALWAYS FOLLOW THE ADVICE THEY GIVE.

The symbol of a lamp directs your attention to explanations of important functions or applica-
tions.

Attention:

 Do not attempt any alterations to this machine without the approval or supervision 

of SPL electronics GmbH. Doing so could nullify completely any and all of your warranty/guar-
antee rights and claims to user support.

The scope of delivery comprises the Track  One, the external power supply, the guarantee card 
and this manual. 

Please  keep  the  original  packaging.  In  case  of  a  service  procedure  the  original  packaging 
ensures a safe transport. It also serves as a safe packaging for your own transports if you do 
not use special transportation cases.

Please note and retain this manual. Carefully read and follow all of the safety and operating 
instructions before you use the machine. Be doubly careful to follow all warnings and special 
safety instructions noted in this manual and on the unit. 

Connections: 

Only use the connections as described. Other connections can lead to health 

risks and equipment damage.

Water and humidity:

 Do not use this machine anywhere near water (for example near a wash 

basin or bath, in a damp cellar, near swimming pools, or the like). In such cases there is an 
extremely high risk of fatal electrical shocks!

Insertion  of  foreign  objects  or  fluids: 

Never  allow  a  foreign  object  through  any  of  the 

machine‘s  chassis  openings.  You  can  easily  come  into  contact  with  dangerous  voltage  or 
cause a damaging short circuit. Never allow any fluids to be spilled or sprayed on the machine. 
Such actions can lead to dangerous electrical shocks or fire! 

Opening the unit:

 Do not open the machine housing, as there is great risk you will damage the 

machine, or – even after being disconnected – you may receive a dangerous electrical shock!

Electrical power:

 Run this machine only from power sources which can provide proper power 

in the range from 100 to 250 volts. When in doubt about a source, contact your dealer or a 
professional electrician. To be sure you have isolated the machine, do so by disconnecting all 
power and signal connections. Be sure that the power supply plug is always accessible. When 
not using the machine for a longer period, make sure to unplug it from your wall power socket 
and from the guitar amp. 

Cord protection:

 Make sure that your power and guitar amplifier signal cords are arranged 

to avoid being stepped on or any kind of crimping and damage related to such event. Do not 
allow any equipment or furniture to crimp the cords.

Power  connection  overloads: 

Avoid  any  kind  of  overload  in  connections  to  wall  sockets, 

extension or splitter power cords, or to signal inputs. Always keep manufacturer warnings and 
instructions in mind. Overloads create fire hazards and risk of dangerous shocks!           >
