For  fast,  easy  and  high  quality  connecting,  Gradient 

Helsinki is equipped with a professional four-pole Speakon 
connector and cable housing. Speakon is very durable and 
easy to connect and lasts hudreds of plug-in and plug-out 
connections. 

If you are not using dedicated 

Gradient cables

, follow simple 

instructions below to prepare your cables with Speakon con-
nectors to work with Gradient Helsinki. (Picture 3. Speakon 
SPX series instructions)

CONNECTING TO THE AMPLIFIER

For  bi-amping,

  connect  the 

ampli

fi

er  driving  woofers

  to 

the poles +1 and -1, and the

 ampli

fi

er

 driving midrange & 

treble drivers to poles +2 and -2.

For single wiring

, the plus wire from ampli

fi

er should be 

connected  to  the  both  plus  poles  (+1  and  +2)  and  the 
minus  wire  similarly  to  the  both  minus  poles  (-1  and  -2). 
This goes easiest with a four pole cable (like Supra Rondo). 
If a two pole cable is used, please c1 and +2 poles 
together with a short piece of insulated wire to avoid short 
circuit (-1 and -2 poles similarly).

In Both cases  we recommend you to use high quality louds-
peaker cable of 1,5 - 4 square millimeters (12-16 Gauge).
