SPEAKER OUTPUTS
These are the speaker outputs for your cabinetry or in the case of a combo, the internal speaker. As
mentioned earlier, we prefer 8 Ohm speakers/loads whenever possible for many reasons from sonic character
to adaptability with other speaker cabinets, and feel your amplifier sounds its best with that impedance loading
it. The 8 Ohm speaker in the 1x12 and 1x10 combo should be connected to the 8 Ohm SPEAKER OUTPUT.
In the 10 and 1 watt positions on the Multi-Watt™ rotary, for a more “proper” impedance match and a different
tone (slightly brighter), you may also connect the single 8 Ohm internal speaker (or extension cabinet if you
have the head version) to the 4 Ohm SPEAKER OUTPUT. This is not essential and it will NOT hurt the amplifier
to leave the single 8 Ohm speaker (or any 8 Ohm speaker load) in the 8 Ohm jack in the two lowest wattage
settings. In fact, you may prefer the sound of this (slight) mismatch produces, as it is a little warmer and smoother
sounding. While a mismatch produces slightly less power, (8 Ohm load on the 4 Ohm speaker output(s), it does
provide an optional response curve and a sound worth auditioning.
When using the combo by itself or the head through a standard MESA 8 Ohm 1x12, 2x12 or 4x12 extension
cabinet, use the 8 Ohm jack. Most MESA 2x12 cabinets are also wired to 8 Ohms and they can be used in this
output as well.
Adding a second 8 Ohm speaker or cabinet we advise connecting them each to a 4 Ohm output. Current and
recent MESA cabinetry also provides a parallel jack that allows daisy-chaining and connecting the first 8 Ohm
cabinet to the 4 Ohm jack this configuration mimics connecting each 8 Ohm speaker to a separate 4 Ohm
output. Regardless of which way you connect this setup, it will provide a better impedance match and ensure
the full power and headroom is available.
A single 4 Ohm cabinet should be used with the 4 Ohm output.
A 16 Ohm 4x12 cabinet or 2x12 cabinet should be used in the 8 Ohm output and will result in a slight reduction in
maximum power, though it will likely be imperceptible with the additional coverage four, or even two speakers,
provides.
Two 16 Ohm cabinets connected to the 8 Ohm output (with a “Y” cord/box) will produce a better impedance
match and will offer the full power and headroom.
NOTE: IMPORTANT! We do not recommend using two 4 Ohm cabinets as this will present a 2 Ohm load to the
output transformer and put undue strain on it as it was not designed for this application.
These common cabinet connection scenarios will cover most of the widely used setups you will run into.
There are likely others less common that we have not identified here, and some may also be safe and unique
sounding. Feel free to call us if you are concerned as it is always better to be safe when it comes to ensuring
proper loading of an expensive tube amplifier. Our Product Specialists will be happy to guide you and/or get
you the proper information regarding impedance matching.
That’s it for the features, controls and interfacing of the California Tweed. We hope this manual and operating
guide helps you get the very best performance from your new amplifier. Here’s wishing you many years of
amazing tone and inspiration from the California Tweed. We feel confident it will reward you many times over
for your initial investment and help you take your playing and musical endeavors to exciting new heights.
From all of us here at MESA/Boogie, Cheers and Enjoy!
