AUDIO CLOCK GENERATION
The standard 44.1, 88.2 , 48 and 96 kHz audio clocks are generated directly from discrete crystal oscillators working in fundamental mode without DDS (direct digital synthesis) or PLL (phase locked loop) circuits in the clock signal path. This vintage technology is not as universal as today's digital clock synthesis circuits because it is limited to only one sample rate (+/- 50ppm) per crystal oscillator, but on the other hand it still provides the purest clock quality with lowest phase noise. Nanoclocks GL also generates -0.1% pull down sample rates using fractional division and a very high frequency PLL circuit.
REFERENCE - INTERNAL
Audio crystal oscillators are tuned to a TCXO timebase accurate to 0.2 ppm.
REFERENCE - VIDEO
Audio crystal oscillators are locked to external SD video syncs with 23.98, 24, 25 (PAL) or 29.97 (NTSC) fps or HD tri-level syncs with 23.98, 24, 25, 29.97, 50, 59.97 or 60 fps.
All SD/HD video frame rates and standards are detected automatically.
Where possible, audio clocks will also be phase locked to video v-syncs (requires a whole-number proportion of sample rate and frame rate). Two reference inputs provide automatic switchover in case of one reference signal fails.
REFERENCE - AUDIO
Audio crystal oscillators are tuned to external word clock or AES-11 DARS signals. Automatically follows 44.1, 48, 88.2, 96 kHz and -0.1% pull down sample rates. Lock range is +/- 50ppm.
The audio reference signals are used to synchronise the internal audio crystal clock generators accordingly, so clock quality is not affected by incoming jittery reference signals.
Select signal from input A or B manually or use the automatic switchover functionality.
REFERENCE - DISTRIBUTION AMPLIFIER
Word clock or AES11/ DARS signals on inputs A and B are directly routed to all 12 outputs. Detected sample rates are displayed and outputs are switched to word clock or AES11 levels according to the present input signal. This mode also distributes all word clock/AES11 signals at non-standard sample rates, i.e. 50kHz.
TERMINATION AND OUTPUT MODE
The connection status of the each clock outputs can be monitored by 12 LEDs: off: output is open, green: 75ohms terminated, red: double, low terminated. The output mode of each individual output can be set to word clock, AES11 DARS or a user programmable signal.
GENLOCK
When synchronising audio clocks to video syncs or other reference signals, it is important not to track disruptions or glitches, to hold and maintain phase lock, to hold the actual tuning when the reference signal fails and to relock very smoothly. For many years, Rosendahl Studiotechnik has been developing and improving software algorithms to synchronise clocks together.
POWER SUPPLY
The unit can be supplied by mains (115/230 VAC switchable) and/or 12V DC using a 4-pin XLR connector, which provides a redundant power system if both power sources are being used. The AC power supply uses a vintage (again!) mains transformer combined with a power saving secondary switching regulator. It is designed for maximum reliability and life span. We know that a reliable master clock generator is an essential part of any studio. Nanoclocks GL consumes 7 watts only.

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
- USED products: 4% of the current new selling price to increase the warranty from 3 months to 1 year. 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
