BLD MICROCLOCKMK2

Product Details

The quality of your digital audio is dependent upon the quality of your digital clock. The better the digital clock, the better the quality of your digital audio. The Black Lion Audio Micro Clock MK2 is the most cost-effective major upgrade to your digital studio. Hear the Black Lion Audio difference. The Micro Clock mk2 is a radical departure in design from its predecessor. It features ultra-low jitter third order crystal oscillators with a revolutionary patent-pending high current parallel drive circuit designed to increase the amount of desirable harmonics within the clock's spectral band. In addition to this, their proprietary noise reduction circuitry dramatically eliminates the unwanted switching harmonics normally found in digital signals. These are musically unrelated signals that create distortion and phase cancellation within the converted audio signal. Because of these technological advances, the Micro Clock mk2 is one of the best performing external word clocks within the pro audio market today.When Black Lion Audio introduced the Micro Clock mk2 they didn't anticipate the amount of demand and controversy that managed to accompany it. External clocking is certainly a hot button issue. Some folks maintain that there's no basis for it. The reasoning behind this is that the device being clocked externally will simply filter the incoming clock signal through its phase lock loop, thereby eliminating any sort of benefit associated with the superior clock. In addition, the simple act of accepting the incoming signal and creating a signal that's in phase will add some jitter.The biggest problem with this theory is that BLA knows nothing about the PLL filter in question; it's completely hypothetical. Many PLL's in pro audio are designed to filter out unwanted signals that are outside of the desired bandwidth, although some are configured to filter out unwanted harmonics that lie within the signal's frequency band. It's incredibly rare to find one that does both at the same time. In the case of the Micro Clock mk2, there is very little undesirable in-band or out of band content (below 10 picoseconds using a Delta Sigma average). There is, however, an abundance of desirable harmonically related in-band spectral content; more so than the average internal clock. No PLL filter is designed to remove these desirable harmonics; they're busy trying to remove the unwanted stuff. Simply put, the Micro Clock mk2 will not only provide audible improvement to your conversion process, but it will do it as well as or better than any other external clock on the market today.The Micro Clock mk2 is simple and probably even boring looking by most standards. It's housed in a rugged yet basic 3 inch by 4 inch chassis that provides optimum RF shielding. It has no lights, no frequency display, and none of the usual visual candy that your friends might envy, but that's because those items create unwanted noise that affect the signal. For a modest black box, it does its job incredibly well and at a price that's unheard of for this level of performance!The power supply is 12 volts DC using a wall wart that's capable of accepting both 120 and 240 volts AC. It features six selectable output frequencies from 44.1 kHz on up to 192 kHz. Output level is approximately 4 volts peak to peak. Jitter at the crystal oscillator is approximately 1 picosecond RMS, and it's just under 10 picoseconds RMS at the output. Both of these figures are obtained using a Delta Sigma averaging method. The Micro Clock mk2 is compatible with all modern digital devices that have 75 ohm BNC word clock input.

When will I receive my shipment?

We ship on business days (Saturday, Sunday, and holidays are not business days). Packages ship from Mississippi, Nevada, New Jersey, or Ohio -- we cannot guarantee that any product will ship from a specific warehouse. Expedited Shipping (1-Day Air and 2-Day Air) is the only way to guarantee that you will receive an item within a certain time frame. Delivery estimates for expedited shipping options are listed on the product page for the item in question. All expedited shipments are delivered Monday-Friday.

Ground Shipping typically takes 1-4 business days from the date of shipment (for orders within the 48 contiguous United States). Residential ground and Free 2-Day shipments are delivered Tuesday-Saturday. Commercial ground and Free 2-Day shipments are delivered Monday-Friday. Make sure to select the proper address type for your address in checkout, as delays may occur if your selection is incorrect.

For APO/FPO customers, all orders ship via USPS. Expedited shipping is not available. Tracking for these orders is not available.

For customers shipping to a PO Box, the order may need to be shipped via USPS. For this reason, expected delivery dates cannot be guaranteed.

Do you ship to my location?

For most products shipping to the continental United States, customers may choose Ground, 2-Day Air, or 1-Day Air delivery. We also ship to Alaska and Hawaii; however, due to carrier restrictions, we cannot ground-ship to those states.

In addition, we ships to the following destinations, though some restrictions apply:

  • Canada
  • Puerto Rico
  • APO/FPO
  • U.S. Territories

See instructions below for how to search the site by our eligible shipping destinations.

Note: We cannot change a shipping address on an order after it has shipped. If an order is returned because it couldn't be received at the listed shipping address, we will accept the return but will not refund the shipping charges.

Canada

We ship a lot of our most popular gear to Canada! To determine if item(s) ship to Canada, add the item(s) to your cart and enter your shipping postal code. Items that ship to Canada are sent via International Air, and delivery is typically 2-5 business days from the date of shipment.

Canadian orders are charged in U.S. dollars. Actual charges are dependent on your bank's conversion rate. Your bank may assess additional fees for international orders.

Although items shipped to Canada receive their full factory warranty, they must be returned to a United States service center for repairs. We're not responsible for any shipping or customs fees incurred in such a case.

Puerto Rico

We ship many items to Puerto Rico. To determine if item(s) ship to Puerto Rico, add the item(s) to your cart and enter your shipping zip code. Eligible items ship via International Air, and typically arrive 2-5 business days from the date of shipment.

APO/FPO

We ship to APO/FPO addresses for free, though over-sized items may be ineligible. To determine if item(s) ship to your APO/FPO address, add the item(s) to your cart and enter your shipping zip code.

U.S. Territories

We ship eligible products to American Samoa, the Federated States of Micronesia, Guam, the Marshall Islands, the Northern Mariana Islands, Palau, and the Virgin Islands. Eligible items typically arrive 2-7 business days from the date of shipment.

What about customs fees?

Please be aware of customs fees such as taxes and duties, which are not included in our shipping charges. Customs fees vary from location to location. Please check with your local customs office for more information on the fees in your area. If you refuse to pay these fees, your order will not be delivered. We cannot refund shipping charges if an item is returned due to refusal to pay fees, and a restocking fee may be applied to cover the cost of return shipping. Customs fees are non-refundable.

Which items ship immediately?

Most orders ship the same business day your order is placed when you place a valid order before the shipping deadline.

Immediate shipment is available Monday-Friday. A valid order placed before 5 p.m. EST will ship the same day when using Ground or Free 2-Day shipping. Ground and Free 2-Day shipping orders placed after 5 p.m. EST will ship the next business day. Many orders using an expedited shipping method (2 Day Air or Next Day Air), and placed before 10 p.m. EST, will ship the same day.

Shipment and availability information updates from our warehouse to our website almost in real time. We are highly confident of the status of each item when you view a page. However, we do not reserve inventory being viewed or even placed in shopping carts, so we cannot guarantee an item's availability until you have placed your order. In particular, if you have been in the checkout area for more than about 10 minutes, we do recommend that you refresh the page to get the most current inventory prior to checking out.

What is a valid order?

A valid order is for a valid item at a valid price, placed with a credit card with complete and verifiable address and other information. Details.

Does immediate shipment mean immediate delivery?

Once an order is shipped, our carriers (Federal Express and UPS) typically guarantee a service time for when the order will be delivered to you. Our carriers have a very good record of delivering at their promised service time. We will ship immediately, and on all items, we will refund expedited shipping charges if the carrier's service levels for your chosen shipping method are not met.

If a product is in stock, is there any reason it will not ship immediately?

Exceptions are very unusual, but here are some examples of reasons that might prevent us from shipping immediately:

  • Warehouse, call center, or web operations lose power or telecom connectivity.
  • Warehouse, call center, or web operations lose capability due to adverse weather (blizzard), safety threat, or other factors.

What can I do if I don't feel you've lived up to your guarantees?

If you ever feel we have not lived up to any of our guarantees, we want to know about it -- and we want a chance to do right if we agree. Contact Us.
