1) Supply input. Apply 9V
DC
from the wall adaptor provided in the package of from an
E vo S 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
F ACE E 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
E vo S UPPLY are
connected to the
E vo C LOCK.
