VC-50H Vintage Club Amplifier
The Rear Panel:
17. AC LINE CORD: Connect the male end of this heavy duty
power cord to a properly grounded AC power outlet of the
correct voltage. DO NOT attempt to defeat the ground pin of
the power cord! (If your amplifier was purchased outside the
United States, see the rear panel serial number label for volt-
age and current information.)
18. IMPEDANCE SWITCH: For the best performance and
least strain on the amp, you MUST match the amp's
impedance to that of your speaker cabinet(s). Set the
selector switch to the 8 or 16 ohm position, depending on
the total impedance of your cabinets. The chart below can
help you determine that impedance based on the follow-
ing combinations of speakers connected in parallel.

19. SPEAKER JACKS: Connect the amplifier to your speak-
er cabinet(s) via these jacks, using heavy-duty speaker
cables (not instrument patch cords). Use cabinets rated at
8 ohms or higher, in combinations which never create a
load lower than 8 ohms. Make sure the Impedance switch
(#18) is properly set. Always use the MAIN speaker jack
first, then connect to the EXTENSION jack if using more
than one cabinet.

Connecting to the Effects Loop Jack:
The front panel Effects Loop jack (#6) lets you patch
external effects into the VC-50H just prior to its power amp
stage. When using Crate's CYC6MS stereo-to-mono Y-cord,
connect its 1/4" stereo plug into the amp's Insert jack, its
"send" plug into the IN jack of the effect and its "return" plug
into the OUT jack of the effect.
Another method is to buy or make a stereo-to-mono Y-
adapter (such as Crate's CA11Y) and use two 1/4" signal
cables to patch into the effect as shown below.
