Please note: the LavryBlack DA10 is a discontinued product.
The LavryBlack DA10 is a stereo digital to analog converter that accepts stereo digital audio via XLR, RCA, and optical inputs and outputs line level analog audio. There is also a built-in headphone amplifier and front panel 1/4" headphone jack. A stepped analog Volume control adjusts both the main line output and the headphone output level.
For general information see digital to analog converter.
- "Crystal" Ultra low jitter PLL mode to minimize source degradation
- Accepts input sample rates between 30kHz and 200kHz
- Potentiometer-free digitally controlled analog volume circuitry
- High power discrete headphone output
- XLR, RCA (Coaxial) and Optical (Toslink) digital inputs
- Balanced or unbalanced outputs with Polarity Inversion
- Mono mode; useful in mixing and recording applications
- Live/Location Sound
- Post Production
The XLR outputs can be configured for balanced or unbalanced connection using the internal jumper settings for "pin 2" and "pin 3;" which refer to the pin numbers of the XLR output connectors. The standard wiring for XLR to RCA adapters or adapter cables is to connect Pin 3 to Pin 1 ("ground") and pin 2 carries the signal. Thus, the correct internal jumper setting for both the XLR to RCA adapters and standard adapter cables is "Pin 2 Hot unbalanced." Please see DA10 manual for setting instructions, and the Operation section of the manual for more details.
Here is an illustration of the jumper settings for one channel:
The XLR output is Pin 3 "+" and Pin 2 "-" for normal signal polarity. Thus, for balanced or unbalanced Pin 2 "+" connections, the "hot" signal polarity is "normal" or "non-inverted" when the front panel POLARITY switch is set to "invert" Changing the Polarity setting to "normal" will result in inverted signal polarity for balanced and unbalanced Pin 2 "+" connections.
The front panel headphone output is driven by a discrete high-powered headphone amplifier that is capable of driving even low impedance HiFi headphones with ease. High efficiency headphones or "earbuds" designed for use with portable audio gear are not recommended for use with the DA11 as the headphone drivers could easily be damaged by the high power of the headphone amplifier. Please exercise care when to reduce the Volume of the DA11 prior to connection of headphones.
The digital inputs consist of (1) female XLR,(1) RCA socket, and (1) Toslink optical input.
The status of the digital input is displayed by the DA1o front panel "Lock" indicator. If the input is "locked" to a valid signal; the front panel Lock indicator will illuminate. If it is not locked due to no connection or an invalid signal; the Lock indicator will not illuminate. If you have any problem when setting up the DA10 or using a different input, please check the Lock indicator to see if the DA10 is locked to a valid input signal.
- Please note that the outputs of many multi-disc players can carry multi-channel formats as well as stereo. In most cases; the player will switch to "stereo" mode automatically when a CD is inserted; but tin cases where it does not or a different format disc is inserted, it may be necessary to set the players output to stereo format manually.
- The optical connection is similar to ADAT Lightpipe format. Many digital audio interfaces used in recording allow the optical I/O to be set to either format, and may default to "ADAT." If the DA10 does not indicate "lock;" please check to be certain the digital audio interface is set properly.
It is advisable to unplug headphones when not using them, or prior to power turn-off or turn-on; particularly high-efficiency headphones
