You want to test your DAC or other digital audio equipment?
You don't want to use computer, due to a noise, ground loops, space?
You need the mains or the battery operated device?
JKGEN - is for you!
Digital function generator with SPDIF, TOSLINK, DSD and I2S outputs.
Now - with DSD!
Now - with DSD!

7 things, making this device better then PC with a sound card:
Not everyone PC's sound card have SPDIF/TOSLINK outputs.
Not everyone PC's sound card have I2S output
Not everyone PC's sound card have external MCLK input
JKG 384-12 is much smaller then desktop PC
JKG 384-12 have less surrounding cables, then desktop or laptop with external sound card
JKG 384-12 can be powered from the battery, allowing "on field operation"
JKG 384-12 can be powered from the battery, avoiding the ground loops
