Radio Design Labs TX-A2D balanced to unbalanced converter

22/06/2017 Leave a comment

I need something like this for my arsenal of audio tools. Like some time back, I had a request from a customer to record their AGM. I have a Behringer UCA-202 USB audio device but the inputs are unbalanced. So from the sound board, I take a balanced output and send send it to the Behringer. I can also take a feed from the headphone out but what if the console is far away?. I also have at my disposal an Extron BUC 102 but that one requires a power supply. This one does not. And it is pretty small…just like what audio tools should be.

Philips OTT2000 micro sound system

06/10/2015 Leave a comment

There have been a lot of these all-in-ones surfacing recently and this Philips OTT2000 is one of them. This one is pretty impressive. It can play back sources using Bluetooth connectivity, you can play back from a USB drive. It has a built-in tuner so you can turn to your favourite radio stations. It also has a CD player and a turntable….all played though built-in speakers. And therein lies the reason why I do not care for it. First of all, the plastic tone-arm. Any tone-arm made of plastic sends warning bells ringing. And the built-in speakers. This is gonna set the rumble stats of this player, when it is playing vinyl, through the roof

If you ask me, If you want to get a good vinyl player, get a good set of speakers, an amplifier with a built-in PHONO RIAA preamp stage, and a turntable. Those Audio-Technica ones which are direct-drive only go for slightly more than $400 at Mustafa in Singapore. Then at last, you will have a good sound-system to enjoy your vinyl.

RCA to 1/4″ phone plug jack

23/02/2012 Leave a comment

All DJs and sound technicians need to get a pair of these. I will give one scenario. What happens one day when you have to plug your DJ controller, for example, into a mixing desk that does not have RCA jacks? For that very reason, I had to use mine twice this year alone and I am very lucky that I have a few of these. Always have a pair in your tool-box. They will save your gig, in more ways than one, and in times when you least expect it

D.A.S. Audio Arco 24 speaker system

18/02/2012 Leave a comment

I just heard about this D.A.S. speaker system the other day. This one sounds just about perfect for an outdoor bar or an alfresco setting because it is weather resistant. So that makes it ideal. According to their website, this speaker boasts:

-Molded high-impact ABS enclosures
-Available in black or white color options
-Small size and ready-to-paint exterior
-Adjustable ceiling/wall mount included

The Arco 24 incorporates two 4” woofers with weather resistant polypropylene cones. High frequency reproduction is handled by a 25 mm neodymium dome tweeter for brilliant highs and balanced performance. An Overload Safety Circuit protects the speakers from damage in case of overpowering.

IP-54 versions are available for outdoor use.

RMS Power Handling 100 W
Peak Power Handling 200 W
Frequency Range (-10 dB) 65 Hz-22 kHz
Nominal Impedance 8 ohms
On-axis Sensitivity 1 W / 1 m 89 dB SPL
Rated Peak SPL at 1 m 115 dB
Dispersion 80ºH x 70ºV
Enclosure Material Paintable ABS Plastic
Color/Finish Black or White
Connectors Spring-Loaded Terminals
Dimensions (H x W x D) 34 x 15 x 15 cm
17.7 x 5.9 x 5.9 in
Weight 2.6 kg (5.7 lb)

Looks like quite a few manufacturers are dabbling in outdoor speakers. Last count, I only counted Technomad and One Systems to have such speakers. Looks like I may have another one on my list when it comes to outdoor installations! Polypropylene cones. Hmmm…gets one thinking…

Stereo Y-Cable

16/02/2012 Leave a comment

Every DJ should have this stereo Y-cable in his or her box of tools. You never know when you need it. There was once when I had to break out my trusty Android phone and download a requested song for a customer while at a party. Luckily I had one of these cables in my bag. I promptly hooked it up to my mixer, on a spare channel and plugged the stereo mini-jack into my Android phone. Played the song for the customer who was impressed that I had it. I can also use this cable to plug into my Hercules DJ controller as it has a mini-jack output. many people have iPhones these days. It can be used for instance, when a client wants to plug his or her iPhone, iPad or laptop into the system for say, music for a presentation. Being flexible will get you more clients in the future. They are not that expensive and can save your ass.

QHA PLC-380 Power Amplifier

12/02/2012 1 comment

In my daily trawls of the Internet, I come across some really interesting stuff. This is another one of them. When I first saw it, I thought immediately that it was a QSC amplifier of old. It even uses the same alphabets in the model number i.e. PLC. This piqued my interest and I find out that it is manufactured (probably in China) for a New Zealand company named SNW Electronics. This company also seems to manufacture and sell motorbike parts. Maybe they are trying to do something what the Yamaha Corporation is doing, I just do not know. In any case, the specs of this amplifier are, as taken from their website:

Stereo Mode:

Both channel driven 8ohm : 1200W X 2
Both channel driven 4ohm : 1800W X 2
Both channel driven 2ohm : 2700W X 2

BRIDGE Mode:

Bridge Mode 8 ohm : 3400W
Bridge Mode 4 ohm : 5200W
Friequency Response HZ: 20-20K
THD+N: 0.02%
S/N: 90dB
SLEW RATE: 40V/s
INPUT IMPEDANCE: 20kohm
INPUT SENSITIVITY: 0dB
MAX INPUT GRAIN: +_20
HEIGHT : 3U
DIMENSIONS:480W x 465D x140H mm
Gross Weight (kg) :42

It costs about NZD$1200 and it looks like it is a pretty hefty amplifier, with a weight of 42 kilograms. I am not too sure how it performs as the specifications are merely words on paper. The specs look good from what I see but reliability-wise…I ain’t too sure.

Electro-Voice ELX112P Powered 12-inch two-way full-range loudspeaker

11/02/2012 Leave a comment

I have heard that these powered speakers can give the Mackie SRM450’s competition and they are cheaper than them too. Pretty impressive specifications and they are lot lighter than the Mackies too! Boasting a 1000 watt Class D amplifier and having fuller sound than many loudspeakers in their class. Specifications are

  • ELX112 performance with self-amplification
  • 50 Hz – 20 kHz frequency range
  • Lightweight, cool-running 1000 W Class D amp
  • Biamped with 24 dB/octave crossover
  • Transducer protection
  • Bypassable high-pass for external subwoofer
  • XLR, TRS, and RCA connections
  • Versatile gain, mixing, and processing controls
  • Pre- or post-mix parallel outputs

Not too bad considering. There are two inputs in the back and you can hook up an MP3 player AND a microphone as there is a built-in mixer, of sorts. Flexibility is the key. Might need to check out how much these cost here.
