Replace UPS Batteries

If you have computers or electronics that you don’t want to be killed by power fluctuations, it’s a good idea to have a UPS (Uninterruptible Power Supply). The battery in the UPS keeps your equipment running through blackouts our brownouts (reduced power).

Dead Battery

The main problem with a UPS is that its battery might only last a couple of years. A dead battery is often announced by a UPS through regular beeping. Because a UPS is expensive, consider just replacing the battery instead of the whole UPS when the battery dies.

You can buy a replacement from the UPS company or for significantly less money from a third party such as Battery Mart. Just be sure to get a battery that is designed for your specific UPS. I have had good luck with with Battery Mart, but there are some third party batteries which are of poor quality, possibly having a short life, acid leakage, or even causing a fire.

I replaced the battery for the APC Back-UPS 500 ES for $26.39 from Battery Mart instead of $48.99 from APC (prices include shipping).

Network Attached Storage for Automated Backups

Prevent Lost Data

Many DC area residents have been contacting me lately with hard drive failures and lost data. Data can sometimes be recovered using software such as SpinRite. But it’s easy and relatively inexpensive to be proactive and backup your data. The best backups are automated, using free software such as SyncBack for Windows or the built-in Time Machine for Macs.

Backup Locally

Backups can be sent to a local USB flash drive or local USB hard drive. The Western Digital My Passport Essential 500 GB costs about $107. These use laptop hard drives which have the advantage of being able to run only on USB power. Larger 3.5 inch external drives can hold more data but require an additional power supply.

Network Backups

If you have more than one computer, a better solution can be to backup to a network attached storage (NAS) drive. This connects by ethernet to your router allowing you to connect to it through your home network.

Here are a few solutions:

Apple Time Capsule

If you are a Mac user and you want the simplest solution, you’ll have to pay a lot more for the Apple Time Capsule. Apple just upgraded their large capacity Time Capsule to 2GB for $499. The Time Capsule is both a NAS and a wireless router, so it simplifies your setup. However it is only a solution for automated Mac backups that use Apple’s included Time Machine software.

Buffalo Linkstation

Buffalo Technology Linkstation Pro LS-XH1.0TL 1 TB is a great NAS that costs about $215 currently. It is fast and works as a Time Machine drive for Macs just like Apple’s Time Capsule above, though you’ll have to login to the Buffalo to set up that capability. You pay a bit more for the Buffalo’s speed than the below Iomega. If you are only using the NAS for automated backups, speed is not particularly important. Speed is helpful if you are also using the NAS as a network shared drive. The other advantage of the Buffalo and the Apple Time Capsule is that they are near silent. You have to put your ear right up to them to hear the small fan.

Iomega Home Media Server

Iomega Home Media Server 34337 1TB is a good media server, which is cheaper ($148) but a bit slower than the Buffalo. It is not loud at all, but the fan is noticeable. It includes software for automatically backing up 5 PCs. You can also backup to it with a Mac by using free software such as SuperDuper.

NAS Reviews

SmallNetBuilder.com is a great site for NAS reviews. They also have charts such as this one which show you the speed versus price. I circled the Buffalo and Iomaga drives mentioned above illustrating the Buffalo’s excellent performance.

Multi-drive NAS

For larger businesses or those who want an extra backup of their backup drive, consider a NAS that consists of multiple drives. This could be a RAID (Redundant Array of Independent Disks) box such as a Netgear ReadyNAS. Or it could be a Drobo and Droboshare. These solutions are more expensive and often slower than single drive solutions. But they ensure that your data will safe if one of their hard drives crashes.

Backup Your Data

In the world of computer support, nothing is worse than seeing someone lose family pictures or days of important accounting data. Given the low cost of storage, there is no excuse for avoiding backups. Automated solutions are a simple way to keep your digital data safe.

Line for Apple Store in Arlington Selling iPhone 3GS

Because Apple and AT&T allowed people to pre-order for delivery, the line for the new iPhone 3GS at 7am today at the Clarendon Apple store in Arlington, Virginia, was about 10% of what we saw for the original iPhone and 3G.

In many ways, this was a less significant upgrade than the upgrade to the 3G. Key selling points of the 3GS include: faster speed (network and phone), video recording, better battery life, compass, and higher quality camera.

Several other upgrades are available to the previous iPhone through the recently released iPhone 3.0 OS. The new software includes cut and paste, photo messaging (available later when AT&T enables it), universal search, and a voice memo app.

I’ll probably buy the 3GS in several months when I qualify for the cheaper upgrade price.

Analog versus Digital Sound

When we setup home theaters, we still get asked about the differences between analog sound, such as that from vinyl records, and digital sound, such as that from CDs. While most people are perfectly content with CDs given budget limitations and poor listening environments, analog vinyls will still produce the best sound if you use the most expensive high-end equipment.

michaelfremerSimilar discussions occur when comparing solid-state amps with tube amps, and when comparing digital synthesizers and samplers with analog synthesizers.

With the advent of SACDs, even extreme audiophiles can not distinguish between digital samples and the analog vinyl versions of songs. Similarly, modern digital synthesizers such as the Nord Lead are now considered indistinguishable from true analog synthesizers by most musicians.

Gizmodo has an article about audiophile Michael Fremer and the subject of digital versus analog. Their main point is that while most people shouldn’t spend hundreds of thousands on a music theater, it is important that some people are obsessed with having the best listening experience.

After hearing I’m a Bowie fan, Fremer drops into his near limitless stacks and spins a pressing of “Heroes” with part of the title track’s chorus in German. I’m giggling with pleasure at the frankly obscene level of detail I hear (Ich! Ich werde König!), but of course, I’m hearing the pops and crackles that a 30+ year-old record is likely to have. Shouldn’t a $350,000 stereo system be completely free of such impurities?

“It’s like when you go to the symphony, and the old men are coughing-same thing,” Fremer says. Necessary impurities. Reminders of being in the real world.

This 1993 news story from MTV featuring Michael Fremer is still applicable today:

Music Studio Basics

Since I started working with music studios 20 years ago, I have seen what would have cost $100,000 with reel-to-reel tape equipment now come down to $10,000 with computers. Even more amazing is that home studios which used to rely on muddy sounding 4-track cassette recorders can now produce inexpensive high-fidelity recordings through a computer.

Music StudioAt Tech DC we have setup several music studios, from small one-mic setups for podcasters to 26 simultaneous channel studios to record entire live bands.

The first question to ask yourself when setting up a studio is Mac or PC. While great software exists for both platforms, the Mac is generally more popular for musicians.

While recordings can be done using a laptop, generally you will want a more powerful system in order to add more channels and effects. Effects like reverb can be very processor intensive. If you don’t have an isolation booth, remember to get a quiet computer so that it’s humming doesn’t leak into your recordings. This is another reason that Macs tend to be popular.

The software that records both audio and MIDI (keystrokes, pressures, pitch, etc.) is typcially referred to as a DAW (Digital Audio Workstation). These include Logic, Cubase, ProTools, Cakewalk, and many others.

Logic & Logic Studio (Mac)

Logic was made by Emagic, then bought by Apple in 2002. It is my current favorite and the Studio version comes with loads of virtual instruments that can be played via MIDI.

Garage Band (Mac)

This is easy to use and included in the iLife suite. It is still very powerful and is built using the same engine as Logic.

Steinberg Cubase Software (PC & Mac)

Cubase is an excellent DAW for PC users.

Keyboard Controllers

Korg, Roland (and Edirol), Yamaha and others make keyboard controllers that can be used to control virtual instruments. Depending on the type of music, this can be very helpful. Virtual instruments come with DAWs and can be added on separately. They vary from unreal synthesizer sounds to professional pianos and organs.

Midi and Audio Ins and Outs

PreSonus of Louisiana makes the Firebox that is inexpensive, small, and perfect for very small studios, assuming that you need no more than a couple of Mic/Guitar inputs at a time. For larger studios, they make the 26 channel FireStudio.

M-Audio is a popular name in Audio/Midi interfaces as well as keyboard controllers. They have a 26 Channel ProFire Audio interface and a smaller 6 in X 10 out Firewire interface.

Mackie has long been the most popular brand for mixers. The mixers can be used to send mixed down audio to a small Audio I/O box like the Firebox. Mackie also sells digital Onyx mixers that send multi-channel audio to a computer.

Mark of the Unicorn is another old name in audio and currently sells the Traveler-mk3 audio interface.

Where to Buy Stuff around DC

There is no one perfect solution for everyone. You need to look at your budget, recording needs, and see what hardware and software you are comfortable using. Check out these stores to see the equipment in person.

Chuck Levin’s Washington Music Center is my favorite local store for instruments and equipment. It has been here since 1958. Other local stores to visit are Guitar Centers in Falls Church, Virginia, Fairfax, Virginia, and Rockville, Maryland (formerly a Venemin’s Music).
