Coolest Products and Tech of the Decade

pioneer-plasma300

 

We take a look back at some influential A/V of the past decade.

Back in 2000, few people had high-definition televisions, DVD popularity began phasing out VHS, speedy broadband Internet wasn’t mainstream, and people had just started stocking up on MP3s (the majority illegally obtained).

Companies like TiVo and Netflix that would dramatically change people’s viewing habits were barely out of infancy.

Now we can watch just about anything we want, whenever we want, and almost wherever we want — on our TVs, computers, cell phones. And super-high quality TVs don’t cost a fortune either … far from it, even for sizes equivalent to the super-space-hogging rear-projection sets popularized in the 90s.

To go with higher-quality TVs we also have better looking video content, as Blu-ray (and HD DVD briefly) brought HD to disc form. Those Blu-ray players can even do much more than play Blu-ray discs as the decade comes to a close now too.

We also have higher-quality audio to complete the full home theater experience. Higher resolution of uncompressed soundtracks on disc, and expanded audio options that have come about with the rise of iPod and other mobile/computer-based listening.

So we’re taking a look back at some of our favorites from the decade. We’re not getting into the automation category (though you can use your iPhone to control some of that too), but there’s been plenty else to change the landscape of A/V and home theater.

How to Make Energy Savings Sexy

energy_savings_sexyStandby mode, component selection, automation and power conditioning can be touted as energy-savers.

12.09.2009 — Consumer interest in residential energy conservation has been on the rise since Energy Star-qualified desktop PCs and monitors became available over 15 years ago.

Consumers are well aware of the Energy Star logo when seeking out a new major appliance, heating or air conditioning system, flat-panel LCD TV, or just replacing their light bulbs. Newly built homes can also receive the Energy Star qualification if they meet specific criteria.

But apart from flat-panel TVs, consumers may not be fully aware of the opportunities for energy conservation in audio/video systems for a home theater and audio/video distribution. Receivers, amplifiers and DVD players can be major sources of energy consumption when powered continuously without adequate management.

As a result, an A/V system has the potential to consume as much energy, or even more, than major household appliances.

It’s up to CE pros to:

1.Make consumers aware of the energy consumption options
2.Sell them on energy-saving systems

A/V Energy Consumption

In simple A/V installations for homes with a single home theater system, it is likely that the consumer will actively turn on and off all components as the system is being used. However, in larger homes with multiple systems and multiroom A/V, it’s more likely that equipment will be unattended and left powered on indefinitely.

Such equipment is likely to be hidden away in cabinets, equipment closets and other locations where everyday user access is unlikely.

In addition to consuming more energy when left continuously powered, components (especially amplifiers and receivers) radiate heat. In cabinets and racks, fans are then required to prevent overheating, further contributing to energy costs. Additionally, supplemental air conditioning may be necessary to maintain room temperature.

The potential energy consumption can be estimated for audio amplification in a typical whole-house system. In the case of a four bedroom home with six A/V zones with each zone powered with two channels at 70 watts each, the total amplification required would be 840 watts which could be covered by a 12-channel power amplifier.

Lets assume that this amplifier consumes 35 watts when running idle, and is powered 24/7. Under these conditions, even before a single watt is converted to the outputs, this amplifier would consume during 300 kWh (kilowatt-hour) during one year. This is close to the estimated energy requirement for running a dishwasher over the same period, based on Energy Star guidelines for annual household usage.

Other energy-consuming products that may also be used in the system, including TVs and DVD players, will further increase energy costs.

The simple solution to lowering power consumption of amplifiers, receivers, DVD players, and other components in an A/V system is to manage their usage. This can be accomplished by selecting products, especially those that are Energy Star certified, that feature a standby mode whereby energy usage is greatly minimized.

Energy efficiency can also be improved by setting up control systems to power off devices when not in use.

An important aspect of an audio device or DVD player in conserving power usage is the ability to engage a standby mode. When a product is in standby, it is essentially assumed to be “off” with normal functions disabled, but is still minimally powered. One advantage of a standby mode is that the device consumes little power when not actively being used, yet remains in a state whereby user activation through handheld IR or home automation control is still possible.

Most DVD players, amplifiers, receivers, surround sound preamps and processors, and other audio products include a standby mode. However, the amount of power consumed by such devices while in standby can vary. Some products may draw less than 1 watt in standby, while others may draw several watts.

One way to help ensure that a devices standby power is minimal is to select products that are Energy Star qualified. A requirement is that the product offers a standby-mode power draw no greater than 1 watt. This is similar to the Energy Star program for televisions (though the program has since evolved to include power draw specifications during normal operation).

The ability to engage a standby mode is also important in reducing energy for an amplifier. Another is the efficiency of the amplifier during normal operation or when running idle. Traditional Class AB amplifiers are the most common, but are also known for dissipating significant amounts of heat, thus requiring adequate ventilation and possibly cooling in racks and cabinets.

Class D amplifiers convert a far greater proportion of the incoming power into their outputs, and can therefore be much more efficient with substantially less heat dissipation and reduced power consumption requirements.

When selecting an amplifier for its energy efficiency, look for low power consumption and thermal dissipation specifications. Ideally, these specs should be provided for standby, idle, and typical operation or the more accurate 1/8 power.

An efficient amplifier not only contributes to lower energy costs, but also runs at a lower operating temperature. This helps to maintain the reliability and life of the amplifier, as well as other products situated near it in a rack or cabinet.
Automating, Managing Energy

In setting up home automation systems for clients, CE pros can create master controls that allow the client to turn on and off multiple devices at once. Separate controls can be created depending on the specific function, whether listening to music throughout the house, watching TV in multiple rooms, or using the home theater.

With these controls, the owner can easily manage system usage with a touch of a button, from anywhere in the house, without having to directly access products that may be hidden away in a cabinet or rack.

In addition to active system control, CE pros can also set the components in the A/V system to be automatically powered on at a specific time during the day, and then shut off for the night. To further realize energy savings, separate schedules could be employed for the work week and the weekends.

Another way to manage energy consumption through automation systems is to set them up to monitor activity. If no user interaction, motion detection, or A/V signal activity is detected over a predefined period, one hour for example, then the devices would be powered off by the control system.

Power management is an effective approach to improving energy efficiency for A/V systems. Reducing power consumption can be achieved by ensuring that audio products and DVD players have a standby mode to ensure minimal energy consumption when not being used, and by actively or automatically managing their usage with key home automation features.

Because audio devices and DVD players can be a significant draw on energy in the home, the energy savings through effective power management can also be significant. It’s comparable to removing a major appliance, such as a dishwasher or clothes dryer. Effectively managing power usage for A/V systems leads to energy cost savings, reduced environmental impact, and enhanced product reliability.

13 Classic Rookie DIY Mistakes to Avoid

diy-tips-framingIf you’re just getting started or planning your home theater and AV projects, here are some pointers from our custom electronics pros friends.

We asked custom electronics (CE) pros about the blunders they encounter when DIYers or inexperienced pros can’t get their systems to work.

Here are some of the rookie mistakes you should avoid:
Buying the least expensive gear and finding out it doesn’t have the features you need, like discrete control codes (on and off, for example) or enough inputs and outputs.

Hooking up equipment using substandard cables, connectors and adapters, leading to poor performance and, eventually, no performance.

Underutilizing gear that you already have. For example, connecting the DVD player using composite cable when it has component or HDMI outputs, and not setting the TV to the maximum resolution.

Never realizing you could be watching HD channels you’re paying for: “You mean Channel 4 is standard but 404 is HD?!  I never knew!” 

Compromising setups that you learn to live with, like having to leave a cabinet door open, or moving cables from one device to another.

Forgetting to install Ethernet jacks at the A/V locations.

Skimping on power protection. 

Mounting video devices in poor locations: displays too high and projectors not centered correctly when there’s no lens shift available.

Failing to wire distributed audio speaker locations for stereo.

Forgetting to put power where it’s needed: racks, TVs, projectors, powered seats.

Trying to use “rules of thumb” for speaker locations in unusual rooms, such as those with missing walls or angled seating.

Wiring low-voltage cabling parallel with the electrical, often done in retrofit situations when the installer or DIYer simply uses the same holes used by the electrical wires.

Inadequate ventilation for equipment, resulting in burned-out gear (and calls to the manufacturer for their “faulty” products).
