Harman Kardon AVR 360 Audio Video Receiver Teardown

27 April 2010
The following is an overview of a teardown analysis conducted by IHS Technology Teardown Services.

Overview / Main Features

The Harman/Kardon AVR 360 is a 7.1-channel audio-video receiver unit capable of delivering 65W of power (7x channels) targeted at the European market (US version is marketed under the AVR 2600 brand). The Dolby 7.1 receiver is a capable high-current (35amps) amp which also features video upscaling for 1080p HD content. The receiver box comes replete with multiple input and output supports of legacy as well as modern connections such as HDMI and adaptor ports for iPhones and iPods.

Pricing and Availability

Pricing - The North American version of the AVR360 is called the "AVR 2600 which as a retail channel price of approximately $700 at the time of writing.

Availability - Europe

Volume Estimations

For the purposes of this teardown analysis, we have assumed a lifetime production volume of 100,000 units.

As a reminder, teardown volume production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed, volumes increment by an order of magnitude. Minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis.

What Is Not Included in our Cost Analysis

The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.

Manufacturing Notes

Country of Origin / Volume Assumptions

Based on markings, the unit was assembled in China. Furthermore, we have assumed that custom mechanicals (plastics, metals, etc.) were also sourced in China.

Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies (such as display modules), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.

Remember also that labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. ""Auto" inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pin-count of the device. This calculation is affected by country or region of origin as well

Design for Manufacturing / Device Complexity

The Harman Kardon AVR 360 has an overall component count of 3253 (excluding box contents), of which, 784 are mechanical in nature.

Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design. The cost of manufacturing is also, to some extent, decreased in this case because of assumed labor rate applied for China.

Note that manual labor has a much smaller effect on auto-insertion assembly lines (for the Main PCB, for example), where manufacturing costs are much more capital equipment intensive and driven by these investment costs.
