Rane RPM 26v - Manual (Page 2)

Manual-2
FRONT PANEL DESCRIPTION
ቢ Signal/Overload multi-color LEDs indicate the presence of a significant audio Signal (green) or Overload conditions (red).
Both Input and Output indicators are provided for signal flow verification without a computer. The Inputs’ Signal indicators
are driven from an analog comparator circuit prior to the input level control. All other indicators are controlled from the
microprocessor.
The Output indicators cycle yellow from left to right during power up and when the unit is loading a new DSP Program.
All outputs are muted during DSP Program changes.
If Output 1 or 2 is flashing, something has gone wrong. See TROUBLESHOOTING on page Manual-22.
ባ COM (yellow, communications) flashes when a message for the unit is successfully received. This indicator flashes often
when communicating with the computer, since metering messages are continually requested by the computer. The COM
indicator may flash so often it may appear to be constantly on. There is also a brief flash whenever the Memory Recall Port
is used.
ቤ POWER indicates that the unit is connected to a powered RS 3 remote supply.
RPM 26v CONNECTION
When connecting the RPM 26v in your system, leave its
power supply and the amplifiers for last. This gives you a
chance to correct mistakes before damage is done to your
amps, speakers, ears, etc. Also, be sure to read the Important
Note in the QUICK START section on page Manual-1.
The RPM 26v has balanced Inputs and Outputs, with
shields connected to the chassis through three #4 serrated
screws on the rear. Keep these screws tight for the best
possible shield-to-chassis connections. The RS-232 cable
shields connect to the chassis through the four nuts and star
washers that the cable screws into. Be sure to screw down
RS-232 cables to guarantee good shield connections. The
chassis and the audio signal ground are connected together
internally at only one point. The RPM 26v chassis connects
through the RS 3 power supply cables to the earth ground (3
rd
pin) of the 100 and 120 VAC line cords. A 6-32 screw and
star washer are also provided on the unit’s rear if a technical
ground connection is needed. This chassis connection is also
recommended for 230V operation. Connect the non-inverting
(positive) audio lines to the ‘+’ terminals, and the inverting
(negative) lines to the ‘–’ terminals. Connect the cable shields
to the center terminal on the Euroblock. For those installa-
tions where the RPM 26v internal shield-to-chassis connec-
tion causes interference, connect the shields directly to the
chassis PEM nuts directly above each shield terminal. Be sure
to bite through the paint with the star washer and keep the
shields wrapped around the audio conductors as much as
possible. For the “theoretical” best ElectroMagnetic Interfer-
ence (EMI) immunity, connect the shields at both ends of the
cables. (For more information on System Connections, see
RaneNote 110, “Sound System Interconnection” later in this
manual or on Rane’s web site at www.rane.com.)
For those systems where Murphy and his EMI pests have
arisen or for those who wish not to tempt fate, the RPM 26v
accepts optional line level input isolation transformers (Rane
part #00961). Call your Rane dealer for more information on
the optional transformers.
To control the unit from a computer, use 9-pin RS-232
cables which are 50 feet or shorter. The cable and adapter
must not be a null-modem type. A short cable is supplied for
connecting adjacent units. Daisy-chain up to 16 units at a
time by connecting the computer COM port to the RW 232
INPUT connector on the first unit. Then connect the unit’s
RW 232 OUTPUT connector to the next unit’s RW 232
INPUT.
The DEVICE ADDRESS switch identifies each unit with
an ‘address’, and must be set uniquely for each unit. The
switches form a binary code from 0 through 255. Only the
numbers 1 through 250 may be used. The place values of
each switch are marked on the rear panel. The switch itself
may have numbers printed on it; these should be ignored. To
set a specific address, refer to the SETTING THE DEVICE
ADDRESS section on page Manual-24 or run the Address
Calculator software included with RaneWare.
Refer to page Manual-23 for information regarding switch
connections to the Memory Recall Port (MRP).
