Protect your HDTV wherever it is

These days, a lot of people want to watch TV shows and movies when and where they can. And that may mean in a kitchen, bedroom, den, or home office. These smaller rooms demand space-efficient TVs and associated equipment. However, you still need to protect your HDTV and other sensitive electronics from damage caused by common power surges and spikes.

The compact Monster HTS 350 protects your valuable gear with advanced surge protection — over 3240 joules of surge absorption capacity (that's a lot). Dual Mode Plus™ circuitry provides another layer of defense against power surges and spikes by automatically disconnecting the power to your components to isolate them from potential damage. And just for good measure, a pair of coaxial RF connections protect against surges and spikes that can sneak into your system via cable TV, satellite, or antenna lines.

Clean power and clean looks

The HTS 350 features patented Monster HD Clean Power™ filtering to remove electromagnetic (EMI) and radio frequency (RFI) noise from the AC power coming out of the wall outlet, ensuring optimum picture and sound quality. This advanced filtering also reduces wear on the delicate circuitry inside your HDTV and Blu-ray player.

You'll find two side-entry AC outlets, which allow the HTS 350 to fit in tight spaces — even behind a wall-mounted TV. The included mounting plate lets you easily attach the HTS 350 directly to a wall, cabinet, or to your TV's wall mount, for an installation that's super-clean and neat.

Product Highlights:

  • 2 side-entry AC outlets for easy installation behind furniture
  • Dual Mode Plus™ surge protection automatically disconnects power to your components and sounds an alarm
  • HD Clean Power Stage 1 filters electrical noise and interference for better performance
  • 3240 joule rating provides a high level of surge protection

  • warranty: lifetime on the HTS 350, plus a $50,000 connected equipment guarantee (covers equipment damaged by an AC power or lightning surge while connected to a properly installed Monster Cable surge protector)
  • Our 60-day money-back guarantee

Just what I Needed

Crutchfield Customer Review (What's this?)

This compact little surge protector and noise filter worked out perfect. I mounted it to the wall behind the TV.

Pros: Quality Build. Simple to install. Nice form factor.

Cons: The 360 degree swiveling plug would not fit into the recessed space on the recessed AC receptacle I had installed behind the TV. I had to switch the AC outlet in the wall to a traditional flat AC outlet.

Before you buy this product, make sure the electric cord length is long enough for your use. The cord is only 2 feet long. When I asked the manufacture if I can get a longer cord, they told me that they sell one for $25.00 which I think is not reasonable.

Pros: Pretty, connect everything to it

Cons: Electric cord is too short

Very nice compact surge protector

Crutchfield Customer Review (What's this?)

Works fine and easy to use. The plug that goes into wall outlet can rotate 360 degrees. Comes with drywall mounting supplies and mounting hardware to connect it to the a TV wall mount.

Pros: Rotating Plug ended up being important for my component furniture installation.

Cons: Only has two outlets, one for the TV and one extra.
