Mesa Boogie PowerHouse Attenuator 4 Ohm

Presenting the all new Mesa Boogie PowerHouse Attenuator, this one in 4 Ohm.

Every experienced player knows there’s nothing like a great tube amp cranked up and running in the power band for Tone, feel and excitement. Be it a 30-watt Combo running 6V6 or EL84s, or a full-blown 100-watt Head cranking with 6L6 or EL34s, nothing compares to the dynamics, expressiveness, fullness and dimensionality of a tube power amp operating in “the zone”. These days however, venue volumes are down and neighbors everywhere aren’t as tolerant as they once were. That’s no reason to compromise your sound and run your favorite amp in its less dynamic idle zone because now Mesa has got you covered with their new PowerHouse® Reactive Load Attenuator.

Aficionados, this is the power attenuator you’ve been waiting for. One that puts Tone and feel first and includes valuable features you need while preserving the magic of your tube amp in all its harnessed-volume glory.

Mesa starts with a reactive Load, an expanded version of that used in their CabClone™ IR series, that protects your amp’s power section and imparts much the same frequency and response curve and reacts with your amp’s power section in much the same way your favorite speaker cabinet does, yet allows you to run silently and safely when a live speaker cabinet can’t be used.

With the PowerHouse set to LOAD you can take a signal out the provided LINE OUT (DRY) ¼” output on the Rear Panel and feed your destination of choice, from Impulse Response players to additional amplification for headroom, consoles for re-amping to effects processors or anywhere an unprocessed signal (no Cabinet Simulation such as that found in our CabClone IR Series) is appropriate.

In SPEAKER Mode, the two ¼ SPEAKER jacks on the Rear Panel function just as those on your amplifier do. In either case, the Attenuator is active and you can use it to reduce the output of your amplifier safely The Attenuation Control in PowerHouse is full featured and provides a Bypass plus 4 Power Reduction levels, -4, -8, -12 and -16dB, with the lowest setting featuring an infinite attenuation LEVEL control that allows whisper soft volumes and below. A Voicing Switch rounds out the Front Panel and includes NORMAL, BRIGHT and WARM settings on the 3-position mini toggle. Output to your Live Cabinets are covered as well with two ¼” OUTPUT jacks wired in parallel, so running additional Extension Cabs is easy. The PowerHouse can handle amplifiers up to 150 Watts and is available in 4, 8 and 16 Ohm impedance versions/ratings.
