1) Supply input. Apply 9V

from the wall adaptor provided in the package of from an

UPPLY. Another power supply may be used if necessary, but user must be aware that

in this case the warranty is void. Tip is positive, ring is negative. A minimum current of

500mA is necessary. This input is protected against polarity inversion.

2) MCLK output. Master clock output dedicated to the HI

ACE

vo. This output delivers

22.5792MHz or 24.576MHz, with 3.3Vpp on 75 Ohms load. This output may also be used

with other equipment, but users must be aware that connecting to a high impedance load

may lead to voltages outside the allowed range for logic circuits. A 75 Ohms cable should

be used for best performance.

3) WCLK output. Word clock output. This is a very versatile output which delivers all the

most common word clocks, including some “super clocks” at 5.6448MHz (44.1kHz * 128),

6.144MHz (48kHz * 128), 11.2896MHz (44.1kHz * 256) and 12.288MHz (48kHz * 256).

Output impedance can be low-Z (3.3Vpp on high impedance load) or 75 Ohms (3.3Vpp on

75 Ohm load for matched connection). When the latter option is selected, a 75 Ohms

cable should be used for best performance.

4) Power indicator. Turns on when the stock wall adaptor or the

UPPLY are

connected to the

LOCK.
