Reference Digital Series Inputs

Just like the C2K Competition Series, ZAPCO’s Digital Reference

Series amplifiers accept only SymbiLink™ Balanced Line inputs. This

assures that the amplifier will receive the cleanest and strongest signal

possible. Every Reference Digital amplifier is equipped with an SLDIN.T-F

SymbiLink™ transmitter for each input pair.

Pictured below is the input section of the DC650.6 6Ch amplifier.

Note that Placed with the input section is an input clip indicator. This LED

will illuminate when any input signal becomes large enough to clip the input

stage of the amp. Using this input clip indicator in conjunction with each

channel’s output clip indicator allows you to easily get the maximum

performance from your Digital Reference amplifier.

Reference Digital Fuses

The Reference Digital amplifies are designed to operate under a

wide variety of conditions and they are designed to protect themselves from

misuse. They operate at any impedance from 8 Ohms down to ½ Ohm. This

means the amp must operate with greatly varying current demands. We

want these amps to have all the current they need at any time to do the job

right.

So if the amp protects itself, why use a fuse? That’s there to protect

your car. A fuse is not something you should have to replace periodically.

We use high current, heavy duty, Mini ANL fuses on the Reference Digital

series. This fuse will never fail in normal use or even extreme use, and we

recommend that if your fuse blows you see your authorized Zapco dealer

immediately, to determine the cause of the failure.
