OUTPUT JACKS

The Twin features not only a balanced line out connection, but a series and a parallel external speaker jack, and the ability to change the output impedance.

The Twin has some of the most versatile output connectivity ever on a Fender tube amp – maybe only the actual “Evil Twin” from 1994 and the especially touchy “Princeton Recording Amp” have more possibilities.

From the manual section on the balanced XLR connector: “This jack provides a transformer-coupled, balanced, floating ground output (on pins 2 and 3), which can be used to drive slave power amps or with proper equalization as a send to a mixing console for recording or sound reinforcement.” In other words it’s your one-stop shop for plugging-in to Things That Aren’t Speakers.

Then come the three (count ’em three!) speaker jacks. One is for an external cabinet wired in series, and one is for an external cabinet wired in parallel, and the middle one is for the amp cabinet speakers which are wired in series.

Finally there is the impedance selector switch, that lets you choose between 4Ω, 8Ω, or 16Ω output impedance. With the two 8Ω cabinet speakers wired in series the default here is 16Ω. However, you can remove the two inner power tubes (they are in a row of four – remove the middle two) and switch this to 8Ω to reduce output power to about 60 watts (or about 15 watts using the low power switch). Unfortunately The Twin is designed to operate with four tubes, so you lose most of the amp’s headroom by doing this and it sounds kind of mushy. A better solution to the excessive volume problem is to use an attenuator between the amp and the speakers – but that increases wear-and-tear on the transformer and tubes.
