Lifetime Tech Support

Blow everyone way with this amplifier/ speaker kit! The 5-channel amplifier is the perfect foundation to build the custom home theater you've always wanted. The speakers are awesome as well; designed for High-End Audio systems, larger Home Theaters, or Commercial spaces such as Bars or Restaurants. Included in the Kit is the amplifier as well as 5 single speakers.

Class H Amplifier
Designing and building an amazing surround sound system begins with the right separates and paramount to the mix is the right multi-channel amplifier. This amplifier is a 5-channel Class H amp that supplies 180W per channel of clean power, and when paired with great speakers like ours, you’ll hear music and movie soundtracks with exceptional detail, accuracy and warmth. The advanced circuitry, wide bandwidth, and low distortion capabilities of this amp allow listeners to hear spine-tingling sonic nuances, and this beefy amp can be matched with even power-hungry in-wall or freestanding loudspeakers. Designed with a high-output toroidal power supply and ample heat sinks to keep things cool, this amp has a clean, brushed metal finish and front panel status indicators that add a high-tech ambiance to any equipment rack.

  • High power 5-channel amplifier for audiophile-level home theater systems
  • Provides 120 Watts per channel at 8 ohms/180Watts RMS
  • Includes 5 individual amplifiers in a single chassis with ample internal capacitance per channel
  • Class H amplifier typology combines the benefits of Class A/B for exceptionally accurate music and movie soundtracks in a more efficient design
  • Heavy-duty toroidal power supply for reliable and continuous power
  • Custom-tooled gold and gun-metal plated connectors for superior signal transfer
  • Includes both balanced (XLR) and unbalanced inputs (RCA)
  • Signal auto sensing detects a signal and powers up then powers down when a signal is not detected
  • Front-panel status indicators

Includes Balanced and Unbalanced Inputs
This high current home theater amplifier includes both balanced and unbalanced inputs for more flexible installation options and cable runs. XLR inputs (balanced) include a ground wire which make it a good choice for long (up to 2000 ft) cable runs, while unbalanced (RCA) provide a more reliable signal on shorter runs.

Advanced Class H Hybrid Technology
Our amplifier is a Class H amplifier that combines the benefits of Class A/B in a more efficient package. Class H amplifiers are a variation of Class A/B amps but include high voltage and low voltage rails to modulate power consumption. When power is running high, the amp switches to the high voltage rails. When the amp is running low, it switches to the low voltage rails. The result is more efficiency, cooler temperatures, and a reduction in power consumption while maintaining the warmth and accuracy of a true A/B amp without the "digital" drawbacks (like interference) of Class D amps.

In-Ceiling Speakers
There's a reason our ACE870 has so many rave reviews, customers love the look, sound, and power of this heavy-duty Atmos-ready home theater ceiling speaker. Designed for High-End Audio systems, larger Home Theaters, or Commercial spaces such as Bars or Restaurants. The ACE870 can handle up to 175W of power so you can push volume levels without any sign of stress.

The beauty of the ACE870 is in the design. The Mid-Bass driver is angled at 15', which gives you more placement flexibility than standard in-ceiling speakers. This makes the ACE870 ideal for Dolby Atmos Surround Sound systems since you can place the speakers in multiple places to create an all-enveloping 3D sound experience.

Why Go Trimless?
It's really a matter of aesthetic preference. These flush mounted speakers are hardly noticeable; that is until they're playing. Our Architectural Ceiling Element (ACE) Trimless speakers do not include the 3/4-inch trim you typically see around in-wall and ceiling speakers. The micro flange grilles are attached by extremely powerful magnets that stay put for quick and easy installation. Adds less visual impact on your architectural audio installation.What Are the 

Benefits of an Angled In-Ceiling Speaker?
The angled speaker is a real problem solver because not every space is ideal for custom home theater sound applications. The angled in-ceiling speaker features a 15° angle for the mid bass driver plus a pivoting tweeter for placement flexibility. This speaker can be part of three piece set to handle the front stage of the surround system when both on-wall and in-wall are not a favorable option. The angled design allows the ideal placement in the ceiling closer to the wall just above the monitor. This creates a more realistic sound image when compared to normal in-ceiling speakers that are mounted closer to directly above the viewing area. Standard in-ceiling speakers are generally placed at least three feet from the wall to avoid reflective sound. The angle speaker can be placed within a foot of the wall

Pivoting Titanium Dome Tweeter
The job of the tweeter is to deliver the higher frequencies of music and soundtracks. The tweeter is also adjustable, meaning it can be aimed toward the listening area. This can make a big difference in sound quality especially for dialog and higher frequencies.

How Does this Speaker Mount in the Ceiling?
Customers often ask us if they need special installation mounting brackets on their OSD ceiling speakers. The answer is no and here’s why. All our in-ceiling speakers feature a dog leg (L-shaped) mounting system that is part of the frame. Before you install the speakers, remove the grille and you’ll see several the mounting screws near the front frame. These screws need to be loosened to activate the dog leg clamps. Use a screwdriver to loosen (turn to the left) these screws and the clamp will come loose. When the speaker is in position in the ceiling, tighten (turn to the right) the screw and the speaker will be secured to the ceiling.

What Type of Speaker Wire and What Gauge?
Wiring is not included with in-ceiling speakers so you will have to purchase some. We recommend our OSD Audio CL3/FT4 cable that is UL (fire) rated for in-wall and outdoor speaker installs. This type of cable includes a heavy-duty outer jacket approved for in-wall/in-ceiling installation. The high-quality plastic jacket is also very flexible so it's easy to run the wires inside the wall. As for the gauge, for runs up to 100 feet for background music, 16-gauge will be fine. If the run is approaching or exceeding 100 feet, we suggest 14-gauge wire.

What Is Butyl Rubber Surround?
With almost double the shelf life of foam, butyl rubber has been the choice of speaker designers looking to optimize the sound based upon materials that go together. The Surround is just one of the integral parts of the speaker's motor structure. Butyl Rubber gives the speaker more excursion capability featuring a deeper bass with a wider frequency response, and its shelf life is closer to 25 years compared to the foam at 12 to 15 years.

Testing the Sound Quality of In-Ceiling Speakers
Many customers like to test the sound quality of their new OSD Audio in-ceiling speakers before they install them. Keep in mind, however, that these flush-mount speakers are designed to be used in the wall or ceiling. Uninstalled in-wall/in-ceiling speakers will sound weak and tinny because without the proper enclosure (in this case your house wall) the speaker can’t produce the sound pressure level it needs. If you want to try them out, we recommend mounting the in-ceiling speakers into a box of about 3 cubic ft. or larger; or simply mount them in the ceiling and then listen. This will give you an accurate measure of the sound quality.

Stefan • 12/17/2019, 2:17:43 PM Q Hello,I am interested in this 5-channel amplifier with the speakers. What other equipment would you recommend purchasing for it to be a top notch system? I note that there is no plug for about receiver for plug-ins? What kind of receiver would you recommend? Also what kind of cables would you recommend to optimize the sound?Thanks in advance.Regards.Stefan

A Hello Stephan:This five-channel amplifier is for Home Theater Surround Sound. Channels one, two, and three are for the three front LCR speakers Left, Center and Right speakers and channels four and five are for two Surround Sound Speakers. The Amplifier offers an audiophile sound quality and two hookup options. First is the Unbalanced RCA featuring a single RCA connection for each channel. Typically you will need to spend over $500.00 for an AVR AV Receiver featuring Preamp outputs for all seven channels dedicated home theater processed channels. All Receivers feature Preamp output for at least one Subwoofer, but most have two dedicated mono sub output channels. The second input option features 5 XLR Inputs for a Balanced Differential. Balanced Line eliminates any noise over the line no matter what the length of the XLR Cables. It also increases the signal 6 to 10dB more than double the unbalanced input. Prices start at $1600 for a Preamp processor with 7.2 channels. Most Preamp Processors with XLR output option feature 11.2 channels where you would need a five-channel amplifier and three two-channel amplifiers (11 discrete channels). The kit includes five 8.0" 2-way Angled LCR/Effects speakers. In the US we would recommend our 14 Gauge two-conductor CL3 rated in-wall custom speaker wire. We have either White or black jacket available in 50 to 500 ft lengths.TL/5617
