Speakers - Mesa/Boogie Heartbreaker Owner's Manual

REAR PANEL:
SLAVE: This works great for using the HEARTBREAKER as a master send to a processor or when additional power amps are
needed for additional power. Some players use this patch point to derive an FX send signal and go to other amps for their wet sound,

SPEAKERS: The HEARTBREAKER 2 x 12 Combo packs two of our custom designed Celestion 90 watt 12" SPEAKERS for
faithful reproduction of the sweet retro-minded tone. The HEARTBREAKER 2 x 12 Combo uses two 8 ohm SPEAKERS wired in
series to produce a load of 16 ohms. When using the Head version, check your SPEAKER cabinets' impedance rating and use the
appropriate SPEAKER output jack on the HEARTBREAKER. The HEARTBREAKER is not overly sensitive to mismatches of

combination of the five available SPEAKER output jacks that are found as illustrated on the right side of the rear panel, if you are
viewing the amp from the back. These jacks are as follows: 1 x 16, 2 x 8 and 2 x 4 ohm taps.

may actually be preferred for tonal reasons, as
different loads have different characteristics.
However, it is important to always keep a load
of some kind on your HEARTBREAKER as
damage to the amplifier will result if it is oper-
ated without a load.
Both Combo and Head versions can accom-
modate a wide variety of extension cabinets and
