Rane RPM 26i - Manual (Page 3)

Manual-3
REAR PANEL DESCRIPTION
ቢ Chassis Ground Point: This #6-32 screw and star washer provide chassis ground when needed. The RPM 26i chassis
connects through the RS 3 power supply cables to earth ground (pin 3) of the 100V and 120V AC line cord. This screw can
also provide a technical ground connection if needed, (highly recommended for 230V use).
ባ Remote POWER jack enables connection to a Rane RS 3 power supply. With the AC power disconnected, insert the RS 3
DIN plug into this jack, then connect AC power. To power the RPM 26i up and down, it is wiser to cycle the AC power
cord, rather than to unplug and plug the DIN jack.
ቤ DEFAULT switch recalls Memory 1. This may be useful in case of computer failure and duplicates the function of the
number ‘1’ Remote Memory Switch—without the need for an external switch (See Signal/Overload on page Manual-2).
ብ MEMORY RECALL PORT (MRP) provides the ability to recall one of 8 Memories using contact closures. All 16
Memories can be recalled using Binary mode (see page Manual-23). The front panel COM LED flashes briefly whenever
the MRP switch configuration changes. Since each Memory can contain a different DSP Program (i.e., a 2-way crossover in
one Memory, 3-way in another), in a fixed installation, be sure that all Memories contain the appropriate DSP Programs for
your system. This avoids the problem of accidentally recalling a Memory which could be detrimental to the system. On the
other hand, this feature is useful in rental systems, for example, where fixed DSP Programs can be stored in various Memo-
ries requiring only an MRP wiring alteration to change the signal processing from a 2-way to a 3-way system.
ቦ RW 232 OUTPUT connects to the RW 232 INPUT on other Rane RW 232 units.
ቧ RW 232 INPUT connects to the computer’s COM port, or to the RW 232 OUTPUT of the previous Rane RW 232 unit.
ቨ RW 232 DEVICE ADDRESS identifies each unit uniquely by assigning it a number from 1 to 250. Refer to the Device
Address Table on page Manual-24 or the RaneWare Address Calculator software for binary switch positions.
ቩ Balanced Outputs. Connect balanced audio connections per the RPM 26i CONNECTION section on the previous page.
ቪ AES3 DIGITAL INPUT. See the RPM 26i CONNECTION section on the previous page. This is the serial transmission
format standardized for professional digital audio signals (AES3-1992 AES Recommended Practice for Digital Audio
Engineering - Serial Transmission Format for Two-Channel Linearly Represented Digital Audio Data). A specification
using time division multiplex for data, and balanced line drivers to transmit two channels of digital audio data on a single
twisted-pair cable using 3-pin (XLR) connectors. Issued as ANSI S4.40-1985 by the American National Standards Institute.
