F) RCA Digital Interface
Use these connectors to hook up the Eclipse to CD players, DAT recorders, and other au-
dio gear using RCA connectors. The connectors are two-conductor RCA jacks. Your plug
should have the shield connected to the sleeve with the single shielded conductor con-
nected at the tip. To select the RCA input as the digital source, go to SETUP DIG-IN (DIG-
IN). Set SETUP DIG-IN (CLOCK) to DigIn as well. The RCA output is always active, but
the format of the data being sent out it can either be Pro (professional) or Cns (consumer) as
determined by SETUP DIG-OUT FORMAT (CS-TYPE). You will probably want this set to
Cns if you’re using the RCA output as your main (or only) digital output.
S/P DIF is a consumer digital audio standard, with two audio channels encoded into a single connector. We
recommend the use of professional quality cables made of RG-59/U coaxial cable. Ordinary "hi-fi" type
leads may prove inadequate, especially at the higher sample rates.
 see page 24
G) Optical Digital Interface
Use these connectors to hook up the Eclipse to CD players, ADATs, and other audio gear
using optical connectors. Use a “Toslink” compatible optical cable (while it might make you feel
good to make it yourself, we recommend buying
professionally made optical cables!). Actually, any func-
tional optical cable that fits will probably work… To select two-channel AES-S/PDIF pro-
tocol optical input, select Optical under SETUP DIG-IN (DIG-IN). To select eight-channel
ADAT protocol input, select ADAT under SETUP DIG-IN (DIG-IN), and select the input
channels under SETUP DIG-IN {ADAT-IN} (repeatedly press the soft key to “ungang” the input
channels). If necessary, set SETUP DIG-IN (CLOCK) to DigIn as well. The optical output is
always active, but the format of the data being sent out it can be S/PDIF (two-channel), or
ADAT (eight-channel) as determined by SETUP DIG-OUT (OPTICAL). What’s more, two-
channel optical output can either be Pro (professional) or Cns (consumer) as determined by
SETUP DIG-OUT FORMAT (CS-TYPE).  see page 24
H) Word Clock I/O
Use these BNC connectors with any audio gear that supports word clock. Word clock is a
more reliable time reference than that supplied by the digital audio itself. If synchronizing
to another device’s clock via word clock, use SETUP DIG-IN (CLOCK) set to WClk. The
word clock output is always sending the sampling rate selected at SETUP DIG-IN
(CLOCK).  see page 26. A word clock connection may need termination  see page 55.
I) Serial Port Connect a “9 pin” serial cable (IBM PC type RS232) to this port to transfer information to
and from a personal computer. Do not use the "null modem" type of cable designed for file
transfer between two computers - it will not work.
With the Memory card removed, the BUSY LED on the front panel illuminates whenever a message is re-
ceived at the serial port. Note: If the serial port is “enabled” and MIDI is “enabled,” a command received
over either the serial port or the MIDI In port causes the port not receiving the command to be ignored until
the command is complete.
 see page 51
J) MIDI MIDI is used for instrument-to-instrument digital communications. The Eclipse sends and
receives Eventide system exclusive messages and, in addition, can respond to and generate
certain standard MIDI commands. The Eclipse has three MIDI ports:
In The Eclipse accepts (and processes) MIDI messages received at the MIDI In
port. The connector is “7 pin” and can provide power to a suitable pedal board,
provided you supply power at the “Remote Power In” socket described below.
It can also send MIDI messages from this connector to a suitably equipped
system. This means, for example, that a pedal board can be connected to the
