DESCRIPTION
Congratulations! With buying an Electro-Voice PRECISION SERIES power amplier you have chosen
an appliance that employs the most advanced technology.
P-Series power amps combine outstanding audio performance, highest reliability and operational
stability. Each power amplier employs an RCM-24 Remote Control module allowing centralized
conguration, control and monitoring of all relevant power amp parameters (like output current, output
voltage, load impedance, etc.).
The gapless protection circuitry concept not only prevents the power amp itself but also the connected
loudspeaker systems from being damaged. These extensive protections include Dynamic Audio
Limiters, DC/HF-Protections, Back-EMF-Protection, Inrush Current Limiter, Short Circuit Protection
and of course Thermal Overload Protection for the output transistors and mains transformers.
Four-speed high performance fans guarantee outstanding thermal stability at absolute low running
noise. The ventilation is directed front-to-rear allowing trouble-free operation even in smaller amp-racks.
Comprehensively dimensioned power supply units with low-leakage toroidal transformers provide
extensive headroom far above the stated nominal power.
Mechanical construction and workmanship also comply with the highest precision manufacturing
standards. The rigid sheet steel chassis resists even the most wearing tour operation.
The RCM-24 provides full-size
overview of the system’s entire status
and control over all relevant system
parameters at any time.
The RCM-24 module allows integration into a Remote Control Network consisting of up to 250 power
amps. The Windows Software IRIS – Intelligent Remote & Integrated Supervision – allows controlling
and monitoring an entire PA-system from a single or several PCs. Any operational status like initial
power-on status, temperature, modulation, limiting, activation of protections, deviation in the load
impedance, etc., are centrally registered and displayed, which provides the opportunity to take specic
measures prior to the occurrence of critical operational states. Programming an automatic response for
exceeding or falling below specic limits is possible as well. All parameters, e.g. power-on/off, levels,
muting, lters, etc. can be controlled in real-time and saved in any power amp.
Monitoring the connected loudspeaker systems is performed through measuring output currents
and –voltages of the two power amplier channels. Each time the signal falls below or exceeds set
limit values is immediately indicated and logged, thus detecting and indicating short circuits and line
interruption during normal operation. The integrated impedance test function allows more precise
checking the connected loudspeaker systems. The integrated signal generator is employed together
with the current/voltage testing to measure the connected loudspeakers’ and cable’s impedance
plus over the entire frequency range. The resulting impedance graph is displayed on the PC-screen.
Comparing the measured impedance progression to a reference value is possible at all times, which
allows recognizing even the slightest loudspeaker defects or irregularities.

DESCRIPTION
Next to controlling and monitoring, the RCM-24 Remote Control module provides comprehensive
signal processing functions. It includes a total of 20 parametric lter–, X-over functions, delays, routing
and level control as well as compressors and limiters per channel. All parameters can be freely edited
and stored in the module’s 8 user presets. Independent from network control all DSP-settings (lter,
delay, level) are maintained in case of failure. Additionally, the control inputs of the power amps can be
used for network-independent switching to another preset (e.g. alarm settings with maximum energy
for voice and text announcements).
Therefore, P-Series amps with RCM-24 modules installed full even the highest safety requirements.
When designing the RCM-24, uncompromising audio quality was the highest maxim. AD/DAconversion is performed at a resolution of 24-bit and 128-times oversampling with linear phase; the
internal word length is 48 bits. With this the RCM-24‘s dynamic range reaches 115 dB, which is an
absolute peak value for digital audio appliances.
All conguration, control and monitoring details of P-Series power amps are explained in the
documentation accompanying the PC Windows software IRIS.
UNPACKING & WARRANTY
Carefully open the packaging and take out the power amplier. Next to the power amplier itself, the
package also includes this owner’s manual, the warranty certicate, four stand-feet, six screw-on
connectors (1x 2-pole, 4x 3-pole, 1x 6-pole) plus a set of rack shelf mounting adapters. Please inspect
carefully whether all information in the warranty certicate has been lled in completely, since only a
completely lled in warranty certicate entitles you to stake any warranty claims. The appliance comes
with a 36 months warranty, starting with the date when receiving the good from your dealer. Therefore,
keep the original invoice together with the warranty certicate at a safe place.
INSTALLATION NOTES
Generally, installing or mounting power amps should be carried out in a way that guarantees
continuously unopposed front-to-rear air circulation. When including an appliance in a closed cabinet
or rack shelf system make sure to provide sufcient ventilation. Leave a gap of at least 60mm x
330mm (up to the cabinet’s top ventilation louvers) for air circulation between the rear of the power
amplier and the cabinet’s/rack’s rear wall. Make sure to leave at least 100mm of space above the
cabinet or rack shelf system. Since the temperature inside of the cabinet or rack shelf system can
easily rise up to 40°C during operation, bearing in mind the maximally allowable environmental
temperature during operation for all other appliances installed in the same rack shelf system is
mandatory.
(also refer to “MAINS OPERATION & RESULTING TEMPERATURE”)
13/4“
44.45
The use of rails or optionally available rack
adapters is mandatory as well when installing
the appliance in a rack shelf system to
prevent the front panel from bending.
31.75
11/4“
Caution: For problem-free operation exceeding the maximally allowable environmental
temperature or +40°C is not permissible.
The power amplier has to be protected against: dripping or splashing water, direct sunlight, high
temperatures or direct inuence of heat sources, high humidity, extensive dust and vibrations.
Condensation on internal parts may occur after transporting the power amplier from a cold into a
warmer environment. In that case operation is only permissible after the appliance has gained the
new temperature (after approximately one hour). If foreign objects or liquids have entered the power
amplier’s enclosure make sure to instantly separate the appliance from the mains power and contact
an authorised DYNACORD service centre for inspection before continuing operation.
Do not use any sprays or solvents for cleaning the appliance, because they might severely damage
the surface of the enclosure or lead to dangerous re hazard.

FRONT VIEW
Use the POWER switch located in the centre of the front panel to switch the appliance’s power
on. The soft-start function prevents current inrush peaks on the mains, which in addition prevents
the mains line protection switch from activating during power-on operation of the power amplier.
The loudspeaker outputs are activated via relay switching with a delay of approximately 2 seconds
effectively attenuating eventual power-on noise. The PROTECT LED lights during the delay time and
the fans run at maximum speed. This is normal to conrm the immaculate operation of the protection
circuitry. Upon power-on, all power amps with RCM-24 Module installed regain the state of operation
prior to the last power-off.
For example: if a power amplier had been switched off using the POWER-switch while being in Standby mode, upon power-on it restarts in this exact mode.
This indicator lights when the power amplier has been switched on. Causes for the
POWER-indicator not lighting are: the appliance is not connected to the mains
network, a defective primary fuse, or the power amplier is set to stand-by operation
(STAND-BY LED lights).
This indicator light when the power amplier is in stand-by mode, which can be
activated from the RCM-24 or via Easy Remote. In stand-by operation only the
internal auxiliary power supply unit is activated. The main power supply unit is
separated from the mains.
The PROTECT LED lights indicating that one of the internal protection circuits
against thermal overload, short-circuit, Back-EMF, HF-occurrence at the output, etc.,
has been activated. In that case, the output relays separate the power amps from
the load connected to prevent the connected loudspeaker systems and the power
ampliers as well from being damaged. Whatever caused the fault – e.g. a short circuited speaker cable – needs to be remedied. In case of thermal overload you have
to wait until the power amplier automatically regains normal operation.
The OUT LED lights as soon as an audio signal of approximately 30dB below full
modulation is present. The LED is dimmed when speaker cables are short-circuited
or a protection circuit has been activated.
The 0dB LED lights when the power amplier is driven at its maximum. Higher input
voltage does not result in higher peak output voltage.
This indicator lights as soon as the integrated dynamic limiter is activated and the
power amplier is driven at the clipping limit or generally at its maximum capacity.
Short-term blinking is not a problem, since the internal limiter trims input levels of up
to +21dBu down to a S/N-ratio of approximately 1%. If, on the other hand, this LED
lights constantly, reducing the volume is recommended to prevent the loudspeaker
systems connected from being damaged by probable overload.

REAR VIEW
INPUT A / INPUT B
The inputs INPUT A & INPUT B are electronically
balanced offering an input sensitivity of +6dBu (1.55V)
for direct connection of mixing consoles, etc.
Connection can be established via the XLR-type input
connectors or the supplied screw-on connectors,
which are connected in parallel. The pin-assignment
of the XLR-type input connectors is according to the
IEC 268 standard. In case oating inputs are needed, retrotting optionally available input transformers
is possible. One extension-kit NRS 90208 (Order-No. 121 641) per channel is needed.
PARALLEL CONNECTION
Connection can be established via the XLR-type input connectors INPUT A / INPUT B or the supplied
screw-on connectors which are connected in parallel. In addition, using the PARALLEL-connectors
provides the possibility for connecting the input signal through to feed additional power ampliers,
without the need for extra splitter-cables.
DSP OUT
The DSP output signal – i.e. the post-digital-signal-processing-unit audio signal – is present at the
DSP OUT. The DSP output signal is simultaneously fed to the power amplier output stage and is
correspondingly amplied present at the power amp’s main outputs.
The DSP OUT can be utilized for feeding the digitally processed audio signal from the RCM-24 Remote Control Module to additional power ampliers (without DSP-module); e.g. for increasing the
overall output power. With a nominal level of +6dBu and a maximum level of +21dBu (8.7V) the output
signal is electronically balanced. Output impedance is 100Ω.
CONTROL PORT
The CONTROL PORT offers two freely programmable control inputs and
control outputs as well as the reference connections for ground potential and
+5V. Using the PC Windows software IRIS, the control inputs can be
congured and serve for instance for Power-On / Stand-by switching, preset
switching or parameter control.
The two control contacts IN1 / IN2 are internally set to +5V (open) via pull-up
resistors. Activating the control inputs is possible by closing the contacts to ground potential (pin 3)
via external switches, pushbuttons or relays. The two control outputs OUT1 / OUT2 are carried out as
Open Collector Outputs. In non-active state (Off) they provide high ohmic resistance. In the active state
(On) these outputs are connected to ground.
The outputs serve for signalling internal operational states. They can be used for the direct triggering
of LEDs, indication lights or relays. The +5V reference connector provides power supply for externally
connected appliances with amperage of maximally 100mA. The control outputs allow signal indication
of operational states (critical temperature, exceeding or decline of dened limit values, faults, etc.) at
central operator desks or to other systems (re alarm system, general alert system) even without PC.
For further detail about conguring the control ports, please refer to the documentation accompanying
the IRIS software.

RS-232 INTERFACE
The RS-232 interface is for connecting media control systems as well as
building management systems providing control and monitoring of all
parameters. Communication is established via an easily to implement ASCII protocol allowing trouble-free integration of Remote Ampliers in media and
touch panel control systems. For a programmer’s guide and complete protocol description, please refer to the documentation accompanying the IRIS software.
ADDRESS
The address selection switch allows setting the amplier’s network address,
which, within a CAN-network, can range from 01 to 250 (FA hex). Caution:
Each address may exist only once within a network. Otherwise network
conicts might occur. Address setting has to be performed in hexadecimal
code. The selection switch LOW represents the low-value digit while the
HIGH-switch represents the high-value digit.
Adress-Table:
HIGH LOW Adress HIGH LOW Adress
0 0 Stand-alone 8 0 ... F 128 ... 143
0 1 ... F 1 ... 15 9 0 ... F 144 ... 159
1 0 ... F 16 ... 31 A 0 ... F 160 ... 175
2 0 ... F 32 ... 47 B 0 ... F 176 ... 191
3 0 ... F 48 ... 63 C 0 ... F 192 ... 207

5 0 ... F 80 ... 95 E 0 ... F 224 ... 239
6 0 ... F 96 ... 111 F 0 ... A 240 ... 250
7 0 ... F 112 ... 127 F B ... F reserved
Address 0 (00 hex, factory-pre-set) ensures that the amplier is separated from the remote
communication, so that it does not appear in the system set-up even though it might be connected
to the CAN-bus. When the amplier is powered-on with its address set to “0”, all internal parameters
are set to “0” respectively to bypass and the routing is set to 2-in-2. In that case the amplier behaves
absolutely linear, i.e. signal processing is deactivated.
REMOTE CAN BUS
Each amplier employs two RJ-45 sockets for Remote CAN-bus connection.
The sockets are parallel connected and serve as input as well as for
connecting through of the Remote network. Common RJ-45 patch
cables can be used for rack-shelf cabling. The CAN-bus needs to be
terminated at both ends using a 120ohms termination plug. Detailed
guidelines concerning cabling and bus length are provided in the chapter
“REMOTE CONTROL NETWORK”.
Both RJ-45 sockets additionally carry the balanced audio monitor signal.
The nominal output level is +6dBu (1.55V) while the maximum output level is +21dBu (8.7V).

REAR VIEW
The STATUS LED provides optical indication of CAN-bus trafc. When the
power amplier’s address is set to “00” so that it is separated from the CAN bus, the STATUS LED blinks every 3 seconds. When the power amplier’s
address is set between “01” and “250” and no CAN-bus activity has taken place yet, the LED blinks
every second. As soon as CAN-bus communication is recognized, the LED is activated for at least
100ms whenever the power amplier actively sends data on the CAN-bus.The STATUS LED may also
be activated from the PC. In this case, the LED of the according power amplier blinks fast and steady
while all other status-LEDs within the system stay dimmed. This function is useful for optically monitoring communication and for quickly identifying particular power ampliers in extensive system installations (please also refer to the IRIS software documentation).
EASY REMOTE
Easy Remote provides a simple way to remotely power-on/off the power
amplier. The Easy Remote function is only useful for appliances not
employing a RCM-24 Module. Controlling appliances with RCM-24 Module
installed per Easy Remote is practically pointless.
EASY REMOTE IN
Leaving the pins of the EASY REMOTE IN socket open, i.e. when connecting +5V, the appliance
power is switched on. When connecting the EASY REMOTE IN, i.e. when feeding 0V from the control
output, the appliance enters standby mode.
EASY REMOTE SLAVE
The EASY REMOTE SLAVE connector provides connection for additional appliances with EasyRemote function (e.g. for switching several devices within a rack-shelf ON/OFF).
The switching of the slave-units is delayed to prevent the mains fuses from blowing.
POWER AMPLIFIER OUTPUTS
SPEAKON-type connectors are provided for the power amplier channels
„A“ and „B“. The BRIDGED OUT connector for bridged operation has a
plastic coverlid preventing inadvertent misconnection.
When connecting loudspeaker systems, please mind the polarity
according to the following diagram:
GROUND-LIFT SWITCH
The ground-lift switch allows eliminating noise loops. If the power amplier is
operated together with other equipment in a 19“ rack-shelf, setting the switch
to its GROUNDED position is recommended. If the power amplier is
operated together with appliances with differing ground potentials, setting
the switch to its UNGROUNDED position is recommended.

REAR VIEW
LIMITER
The integrated limiter provides reliable protection against signal clipping and
has a switchable time constant. Leaving the switch set to SLOW is
recommended for general use (factory pre-set status).
When using the power amplier as Mid/Hi power amp employed in active
multi-way systems, setting the limiter switch to FAST is recommended.
When using the power amplier as low-frequency woofer power amp
employed in active multi-way systems, setting the limiter switch to SLOW is
recommended.
BRIDGED MODE
Switch for changing from normal (stereo) operation to bridged mode. In
bridged mode the integrated power ampliers operate in „push-pull“
operation. The output voltages of cannel „A“ and channel „B“ are doubled
and present at the BRIDGED OUT connector. Channels „A“ and „B“ work
phase-shifted in push-pull operation and may not be used as loudspeaker
outputs.
10
CABLING
LF-CONNECTION CORDS
Choosing balanced cables (two conductors for the audio signal plus separate shielding mesh) with
XLR-type connectors is recommended for LF-signal connection. Although connecting unbalanced
cables to the power amplier inputs is possible as well, using balanced cabling is always preferable.
A great number of today’s audio appliances employ balanced outputs. With balanced cabling, the
shield connects all metal enclosure parts and thus efciently eliminates the introduction of noise and
hum.

REMOTE CONTROL NETWORK
The network of the remote power amps is based on the CAN-bus standard, which for years is
especially popular in automotive, industrial and security applications. The CAN-bus is a balanced
serial interface for command and data transmission. Controlling the power ampliers is performed
from a PC with IRIS – Intelligent Remote & Integrated Supervision – software installed. The UCC1
USB-CAN Converter serves as interface between the PC and the CAN-bus. Connecting up to 100
power ampliers per CAN-Bus with a maximum total cable length of 1,000 meters is possible. An
additional CAN-bus is needed for controlling more than 100 power amps while the IRIS software allows
administering a total of 250 power amps.
The network topology used by the CAN-bus is the so-called “bus or line topology”, i.e. all participants
are connected via a single two-wire cable (Twisted-Pair cable, shielded or unshielded) with the cabling
running from one participant on the bus to the next, allowing unlimited communication among all
appliances included. In general, it does not
matter whether a participant on the bus is a
power amplier or a UCC1 USB-CAN
converter, so that both – UCC1 and the PC
as well – can be inserted at any position.
Incorporating several UCC1 and PCs
on a single CAN-bus is also possible. A
total of up to 100 appliances can be operated
on a single CAN-bus. Since the CANinterfaces of all appliances are galvanically separated from the rest of the circuitry, network cabling
also carries a common ground conductor (CAN_GND) ensuring that all CAN-interfaces in the network
are connected to a common ground potential. The UCC1 provides the possibility for switching the
CAN-ground to circuit-ground.
Each participant on the bus system has two RJ-45 connectors for the Remote CAN-bus. These sockets
are connected in parallel to serve as input and output (for connecting through) for the data transfer of
the remote-network. The CAN-bus has to be terminated at both ends using 120 terminator plugs, two
of which – CAN-TERM 120 – are supplied with the UCC1. Connect one of these to the RJ-45 socket
of the rst and the other to the socket of the last appliance on the CAN-bus.
