Digital Designs CM600 Mono-Block Product Review

Posted In: Product Reviews, Views

The Digital Designs CM600 is Digital Designs‘ entry level Mono-Block Amplifier and I use the term “entry level” loosely, 350w RMS @ 4ohm & 600w RMS @ 2ohm may be entry level for Digital Designs but for some other (that I will not name due to respect) car audio brands 600w RMS is a monstrous amount of power for their factory made subwoofers.

 

As usual with the Digital Designs amplifiers the CM600 has nice and simple design with the casing which is a good thing in my opinion, the nice and sleek black anodised aluminium casing makes for a good heat-sink as well as looking stealth enough for the most subtle of installs.

Here at ABTEC we have a CM600 on a comparator board (Sound-Board) with a SS4a and SS1b mounted above it and because of this beautifully simple casing design all three of them look like they all belong. This to me is important as when I have an install done I like it to look as clean as possible and allowing the different series amplifiers to have a similar look/design allows people to make their installs as clean as possible.

With 350w RMS @ 4ohms & 600w RMS @ 2ohms the CM600 is the perfect Mono-Block to power a Digital Designs DD-LE-MINI08 or even two of them! At the moment on the comparator board we have a CM600 powering 4 x DD-SW6.5′s, DD-512-D4, DD-510-D4, JBL GTO1214D, Infinity Kappa 122.7 & a Infinity REF1260W via a switch board which is pushing at least one of these for a minimum of twelve hours a day without any issues!

SPECIFICATIONS

  • Channels: 1
  • Cont power at 2 ohm: 600W x 1ch
  • Damping factor: >100
  • Dimensions (us): 15.75″ x 9.45″ x 2.08″
  • Dimensions (metric): 400 mm x 240 mm x 52 mm
  • Dynamic power: 1200
  • Efficiency thru output: NA
  • Input sensitivity: 0.2V – 6V
  • Shipping weight: 11 lbs / 4.99 kg
  • Wire gauge (power and ground): Spade Terminal
  • Wire gauge (speaker output): Spade Terminal

If you are after an amp to provide clean power to an “entry level” DD subwoofer (or even another brand) the Digital Designs CM600 can’t be beat in my opinion for price you pay for it! Once my new family car has arrived I will most likely be getting a CM600 myself to power two DD-LE-MINI08′s just so I can have a touch of bass for those family outings!

Harman Kardon AVR 265 7.1 Receiver Product Review

by admin on June 13th, 2013 at 11:21 am
Posted In: Product Reviews

It not very often that I am lost for words, in fact if I remember correctly there has only been four or five times in my life that this has happened. One of these times was when I unpacked my own Harman Kardon AVR 265 and the other was trying think of an opening for this review…

So on that note here is Harman Kardon’s blurb on the AVR 265 since I couldn’t of written it better!

“If you’re looking for an AVR packed with next-generation
technology, look no further than the Harman Kardon
AVR 265. The AVR 265 has an impressive list of features
that take your home entertainment experience to the
next level. With HDMI® v.1.4a with 3-D, Deep Colour
and Audio Return Channel, and all the latest Dolby® and
DTS® audio modes, the AVR 265 lets you experience
a new dimension in TV viewing – all while our own
Logic 7® processing creates an exhilarating 360-degree
soundstage via 7.1-channel surround sound. And this
AVR does far more than just movies and soundtracks –
it can even be set to power a Zone 2 speaker system
for multiroom audio. With five HDMI inputs, extensive
video and audio connectivity, and the ability to connect
with The Bridge IIIP for iPod/iPhone playback, the
AVR 265 solidifies itself as a versatile receiver that
can accommodate your every entertainment whim
with grace, style and ease.” – HK

The one thing I have always liked about the design of Harman Kardon Receivers is its simplicity, they have that “quiet person” appeal to them.

We all know that one “quiet person” that is quiet most the time but from time to time is known to get loud and wild, well this is how I see the AVR 265. Most of the time it just sits in the cabinet nice and sleek, not drawing any attention to its classy self then when the lights go out it becomes a complete monster making your movies and or music come alive!

When it comes to sound quality usually there is more to it than having a powerful amplifier/receiver and big speakers to getting a clear clean signal, but in saying that having a good quality amplifier/receiver is a good starting point.

The sound produced by the AVR 265 is very crisp and clean and has more then enough amperage to make the 95w RMS it produce seem like a lot more, even at high volume levels. At the moment I am running 5 x Digital Designs DD-LS-241 satellite speakers and a Digital Designs DD-PS3 12″ home theatre subwoofer on the AVR 265 which produce’s amazing sound, I do plan on getting large floor-standers but for the mean time the setup is already big enough for my lounge and produces movie theatre sound!

I’ve owned the Harman Kardon AVR 265 for close to a year now and it has worked flawlessly with no issues what so ever. It also gets used for at least sixteen hours a day having everything from the TV, Radio, Blu-Rays to Video game consoles being played through it without any issues. Being able to set all the video/audio settings individually for each source is a brilliant idea as I tend to sit in different parts of the room depending if I am playing video games, watching TV or a Blu-Ray.

The Zone 2 option is also a brilliant idea that allows you to play one source in your lounge and another elsewhere in the house via two channels, I how ever have set it up in my lounge to having two sets of fronts instead of using the Zone 2 option to give the stage a powerful sound during movies.

Overall I have to say that if I was to buy another receiver it would be another HK AVR 265 as it has a lot of bang for buck when compared to a lot of the competition and also other receivers I have previously owned too.

ABTEC’s NEW Home Theatre Demo Room

by admin on June 6th, 2013 at 5:04 pm
Posted In: General, News

Since the move to our NEW shop I haven’t found much time to write many blogs so I thought I’d hide in my new office and write about my favourite feature of the NEW building, The ABTEC Home Theatre Demo Room!

This is something I know Ashley has wanted to do for a long time since he has a passion for not only car audio but also home theatre, if you have ever watched a movie at his house you would know exactly what I mean!

The choice of the product used/fitted to the room was actually an easy task since Ashley wanted to keep to our “SOUNDS ALIVE” motto, so that meant keeping everything high-end but at the same time not so high-end that it is out of every bodies reach. So we went with Harman Kardon, Klipsch, Energy, Digital Designs, JBL and Velodyne.

The amplifier/receiver used to power the home theatre is the Harman Kardon AVR660 which has more than enough features to sink a battleship, not only that but it also has more than enough amperage to put a clean signal to any of the speakers used.

Instead of going threw every speaker that has been used in the home theatre room I will just make a list:

  • Energy EP-BAR-E
  • Energy V6.3BLK
  • Energy CF70BLK
  • Energy CB10
  • Energy CC10
  • Energy CR10
  • Energy EAS6C
  • Energy ESWC8
  • Energy VMINIPACK
  • DD LS-241
  • DD PS1
  • DD PS2
  • JBL ES90-BK
  • JBL ES30-BK
  • JBL ES25-BK
  • Klipsch AW-650
  • Velodyne EQ-Max15

I’ve spent many a good hour or so listening to music, watching DTS Blu-rays, playing the Xbox 360 in this home theatre room now and I must say it still blows me away. The definition and clarity from the Energy Speakers and Velodyne Subwoofer is just amazing, when watching “Saving Private Ryan” it was like I was in the battlefield with all the explosions and gunfire.

If you are passing by The ABTEC Showroom or are in the Petone area make sure you have five minutes or so to check out our NEW home theatre room! I can’t explain in words how good it sounds, so the best way to put it would be that its not the same watching movies at home anymore!

Also if you do pop down to 49 Hutt Road, Petone ask Lance or Ashley to demo the Animusic HD Blu-ray as it seems to amaze people of all ages!

Pioneer FH-X755BT Product Review

by admin on June 5th, 2013 at 1:14 pm
Posted In: Product Reviews

As far double-dins go you would usually get two of these three things (Good Price/Quality/Lots of Options) which limits most people to buying a product that they would be half-happy with, Pioneer’s solution to this is the Pioneer FH-X755BT. Now you can have a quality unit with lots of options at a very good price point!

As with most Pioneer Head-Unit’s the display is simple yet effective with enough information displayed without becoming cluttered. There is the option of changing the illumination of the buttons/controls separate to the display to give you that custom feel, also with the controls based around the volume control makes it easy to command without needing to look at the unit while driving.

As to be expected the sound quality of the FH-X755BT is the usual Pioneer standard which is great, it has a 5-Band Equalizer with HPF/LPF (High Pass Filter/Low Pass Filter) so you can optimize your setup with crossover points for your speakers/sub-woofers.

The Bluetooth function on the FH-X355BT has the Parrot module installed which gives you peace of mind that the Bluetooth Hands-Free will seamlessly work to the best of its capability. Streaming music is made easy as well with Secure Simple Pairing (SSP), which means you can pair your Bluetooth devices quick and easy without the need of a pin-code or complicated settings.

My overall opinion on the Pioneer FH-X755BT is it makes a good factory radio replacement for somebody that wants that full double-din look without the need of a DVD player, the fact it has all the functions of a higher price point single-din head-unit so makes it very appealing.

On a last note the one thing that really stands out is the fact it not only works great with iDevices but also with Android ones too! This to me is a big selling/buying point as not everyone that sits in the passenger of my car uses a iPhone/iPod and you can also have two devices pared at the same time be it iPhone or android!

Digital Designs M4a Mono-Block Product Review

by admin on May 18th, 2013 at 3:17 pm
Posted In: Product Reviews

Usually when I do a review on a product I will run it in one of the work vehicles for a week or two testing out different settings and getting a general feeling of how it functions, sometimes I even push the items to its limits. Writing a product review on the Digital Designs M4a is slightly different in this case since I have been running two in ABTEC3 for about a year now and have used them for everything from SPL, Ground-Pounding to just playing Ordinary Everyday Music.

The build quality of the M4a is just flawless, not just aesthetically either but also in how it preforms too! Over the last year I have powered many Sub-Woofer setups with the M4a, including: 4 x DD-510-D4′s, 4 x DD-512-D4′s, 1 x DD-9518-D1, 1 x DD-z18 (the list goes on too) and has always provided plenty of power no matter what Ohms it was run at too!

As stated before I don’t just use a M4a for our SPL setup that has netted us 154.7dB Officially (We use 2 x M4a’s for this) but I Daily ABTEC3 driving a DD-9518-D1 with a M4a @ .5 Ohm and it absolutely loves it! Anybody that knows me knows I like my music LOUD, so LOUD that the windshield in the Toyota Vitz is usually flexing as I commute to and from ABTEC everyday!

As far as sound quality goes the M4a lives up to the Digital Designs motto of True To The Source! I do understand an amplifier can’t be judged on sound quality alone, but in my experience with the M4a and the Sub-Woofers I’ve used with it have produced beautiful sounding Bass. Even down to the low 40Hz-20Hz that I love the most!

What amazes me with the M4a is where most High-Output Amplifiers are rated at 14.4v or even higher, the M4a is still rated at 12-14.v which makes it ideal for everyday use. At 12v the M4a makes 5200w RMS @ 1 Ohm, at 14.4v it easily makes over 7000w RMS @ 1 Ohm and some people have even clamped their M4a’s at just under 8000w RMS @ .5 Ohm on 14.4v!

SPECIFICATIONS

  • Bridged: NA
  • Channels: 1
  • Cont Power at 1 Ohm: 5,200W x 1 @ 12v
  • Damping Factor: >150
  • Dimensions (Inches): 27.625L x 9.13W x 2.5H
  • Dimensions (Metric): 702L x 232W x 63.5H
  • Dynamic Power: 9500W
  • Efficiency Thru Output: 87%
  • Input Sensitivity: 0.15v – 5v
  • Model: M4a
  • Shipping Weight: 36 lbs

Overall the M4a in my personal opinion is the ultimate amplifier for multiple uses, be it Ground pounding, SPL or even powering your daily SQ setup the M4a will have more than enough power for your setup. If some how you need more power just add another M4a and strap them together for double the power!

On an ending note I consider myself lucky that I get use not only one but two M4a’s in my daily, because here in New Zealand there isn’t that many people that drive around with an easy 10,000w RMS on a daily basis… Yet!
