should be used in the 8 OHM setting and will see a slight reduction in maximum power, though it will likely be unnoticeable with the
additional coverage four or even two speakers provides. Two 16 Ohm Cabinets connected in the 8 OHM setting will produce a better
impedance match and will offer the full power and headroom.
NOTE: 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.
The ONLY time it is safe (but NOT RECOMMENDED), to run the amplifier with no Load connected to a SPEAKER Output is when
you are using the CABCLONE D.I. to record Direct and the SPKR ON/OFF switch in the SPEAKER Section is set to SPKR OFF
(switch down). Even THEN, we HIGHLY RECOMMEND keeping a cabinet connected at all times… just in case someone ELSE (Tech,
Recording Engineer, etc.) starts flipping switches on the Rear Panel of your amplifier.
Below are some common and correct SPEAKER Output Connection Examples;
• One 8 Ohm Cabinet – To 8 Ohm SPEAKER Output (One MESA 8 Ohm Cabinet).
• Two 8 Ohm Cabinets – Each to a separate 4 Ohm SPEAKER Output or One Cabinet to PARALLEL Input on MESA Speaker
Cabinet and 2nd Cabinet to other PARALLEL jack On MESA Cabinet.
• One 4 Ohm Cabinet – To 4 Ohm SPEAKER output. (Any 4 Ohm Cabinet)
• Two 4 Ohm Cabinets – NOT RECOMMENDED! Output Transformer NOT setup to run on 2 Ohm Load.
• One 16 Ohm Cabinet – To 8 Ohm SPEAKER Output. (Slight reduction in maximum power)
• Two 16 Ohm Cabinets – Uses Parallel box or “Y” connector to 8 Ohm SPEAKER Output.
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 than sorry when it comes to ensuring proper loading of an expensive amplifier/piece of equipment
like the TRIPLE CROWN. Our Product Specialists will be happy to guide you and/or get you the proper information regarding this
important topic.
SPKR ON/SPKR OFF
This mini toggle mutes the SPEAKER Output for when you want to record “silently” with the CabClone
D.I. (direct with no speaker sound from the amplifier). This switch allows you to decide if you’d like to utilize both a live speaker cabinet
AND the CabClone’s XLR Direct Out, or just the XLR D.I. OUT. Also, while it’s not needed as you have the STANDBY on the Front
Panel for this purpose, this switch may be used as a Mute switch, though with its Rear Panel location this is a less desirable way to
achieve that function.
NOTE: IMPORTANT! The SPKR OFF switch position automatically connects a Load Resistor to the SPEAKER Outputs to prevent
damage to the output tubes and transformer and allow silent (no cabinet connected) direct recording with the XLR D.I. OUT. Select-
ing SPKR ON defeats the internal Load and connects the signal to the SPEAKER Outputs. DO NOT USE THE AMPLIFIER IN THE
SPKR ON SWITCH POSITION WITHOUT A CABINET (LOAD) CONNECTED! Damage to the amplifier will likely occur and this is
not covered under the Warranty! For this reason, we recommend keeping a cabinet or Load connected even when you are using the
SPKR OFF position as an extra measure of safety in case someone other than you (Tech or Sound Engineer) was ever to switch to
SPKR ON in a “Silent” session. It won’t hurt anything and only add a degree of safety.
NOTE: REMINDER! If you have everything ON... POWER, STANDBY, GAIN and MASTER (as well as Input and Output Volume
Controls on any Effects in the FX Loop) and get no sound; Check the SPKR OFF/SPKR ON switch in the SPEAKER Section of the
Rear Panel to make sure the toggle switch is set to SPKR ON. This may have been bumped during shipping, transport or set up.
HEADPHONE
The TRIPLE CROWN features a HEADPHONE Output for personal enjoyment of the amplifier when it is not
possible—or you don’t want to—play through a speaker. This stereo ¼” jack derives its “speaker simulated” signal from the on-board
CABCLONE™ D.I. feature circuitry and delivers a surprisingly good rendering of the TRIPLE CROWN’s sound and feel to your head-
