If you need setup or operational assistance for this product, please call the Peavey Electronics Customer Service Department or your local Peavey Electronics representative. We appreciate suggestions that may help us improve our products and/or service.

UNPACKING

Inspect the amplifier during unpacking. If you find any damage, notify your dealer immediately. Only the consignee may institute a claim with the carrier for damage incurred during shipping. Be sure to save the carton and all packing materials. Should you ever need to ship the unit back to Peavey Electronics, one of its service centers, or the dealer; use only the original factory packing.

INSTALLATION AND MOUNTING

ICA Series amplifiers are 2 or 3-rack-space units of 15 3/4" (400 mm) depth that mount in a standard 19" rack. On all amplifiers, front panel mounting holes are provided.

BASIC SETUP

1. Rack mount the amplifier in the location where it is to be used, remembering to allow for

adequate access and cooling space. For more information, see the sections on INSTALLATION AND MOUNTING and COOLING REQUIREMENTS.

2. Make input connections to the plugable terminal blocks on the rear panel. Use the proper

connections for stereo, parallel, bridged mono, and grounding configuration. See the sections on SIGNAL MODE CONFIGURATION and INPUT MODULE CONNECTIONS for more information.

3. Connect speakers to the output barrier strip. Be sure to make the correct output connections

for stereo, parallel or bridged mono configuration. See the section on SPEAKER OUTPUT CONNECTIONS for more information.

4. Make power connections, allowing for proper current draw. See the sections on IEC POWER

CONNECTOR and AC MAINS CIRCUIT SIZE REQUIREMENTS for more information.

5. Turn the front panel 3-position AC POWER switch to ON and bring up the back panel LEVEL

(gain) attenuators to the desired levels.

ENGLISH

FRONT PANEL FEATURES

1. RACK MOUNTING EARS

These mounting holes are provided on each front mounting ear.

2. 3-POSITION AC POWER SWITCH

A 3-position switch is on the front panel. Sequential remote turn-on capability is a standard feature. With the switch pushed towards the outside position, the amplifier is ON. The middle position is OFF, and the inside position is marked STANDBY. When switched to STANDBY, the amplifier may be activated by the sequential turn-on circuit. See the section on SEQUENTIAL TURN-ON / TURN-OFF for more information.

3. POWER LED

The POWER LED illuminates when the amplifier is turned on.

4. SIGNAL LED

Each channel has a SIGNAL LED that illuminates when the amplifier output exceeds 1 volt.

5. CLIP LED

Each channel has a CLIP LED that illuminates at the clipping point, and indicates that internal circuitry is reducing amplifier gain to allow full power. See the section on PROTECTION FEATURES for more information.

6. LFC

™

LED

Each channel has a LFC (Load Fault Correction) LED. This LED illuminates when the amplifier channel detects an abnormal load condition. Internal circuitry will instantaneously reduce the channel gain to allow the amplifier to operate at a safe level into the abnormal load. See the section on PROTECTION FEATURES for more information.

7. PROTECT LED

If the amplifier has just been turned on or has detected a fault condition, the speaker output relays will open, illuminating this LED.

8. INPUT SECTION

The ICA

™

Series comes standard with plugable input connectors and individual channel rotary attenuators. Connections at the input connector permit the audio signal ground to be connected or lifted from the chassis ground.

9. OUTPUT BARRIER STRIP

A barrier strip is provided for connection of loudspeakers with bare wire or spade lug connectors. This barrier strip can accommodate up to two 10-gauge wires per terminal.

10. IEC POWER CONNECTOR

A standard IEC power connector is located at the upper left corner of the amplifier rear panel. An AC mains cord having an appropriate AC plug for the intended operating voltage is included.

NOTE: FOR UK ONLY If the colors of the wires in the mains lead of this unit do not correspond with the colored markings identifying the terminals in your plug, proceed as follows: (1) The wire that is colored green and yellow must be connected to the terminal that is marked by the letter E, the earth symbol, colored green, or colored green and yellow. (2) The wire that is colored blue must be connected to the terminal that is marked with the letter N or the color black. (3). The wire that is colored brown must be connected to the terminal that is marked with the letter L or the color red.

11. CIRCUIT BREAKER

A resettable, protective AC circuit breaker is located at the upper left of the amplifier back panel. If the breaker has tripped, push it back in to return the amplifier to operating condition. If the breaker continues to trip, the amplifier needs servicing. Do not continue to reset the breaker because severe internal damage and safety hazards could occur!

12. SEQUENTIAL TURN-ON CONNECTOR

The ICA

™

Series comes standard with remote-controllable sequential turn on enabled by setting the front power switch to STANDBY. The amplifier is activated by applying a voltage between 12 to 24 volts DC to the rear-mounted, 4-pin plugable terminal, and connecting the ENABLE terminal to the 24 V DC+ terminal. When no voltage is present or the ENABLE connection is opened, the amplifier will switch off. Other ICA Series amplifiers can be “daisy chained” by connecting all 24 V DC+ terminals together, all COMMON terminals together, and

1110

13 8

connecting the ENABLE OUT to the ENABLE IN of the next amplifier. A mating connector is shipped with the amplifier.

13. FAN GRILL A continuously variable-speed DC fan supplies cool air into the amplifier. Do not block this intake! The fan operates only when the amplifier heat sinks require cooling.

OPERATION

AC MAINS CIRCUIT SIZE REQUIREMENTS

Power requirements for ICA™amplifiers are rated at “idle”, 1/8 power (“typical” music conditions), 1/3 power, and maximum rated power. The maximum power current draw rating

is limited by the amplifier’s circuit breaker. Consult the specification sheet for the current that each amplifier will demand. AC mains voltage must be the same as that indicated on the back of the amplifier. Damage caused by connecting the amplifier to improper AC voltage is not covered by any warranty. NOTE: Always turn off and disconnect the amplifier from the mains voltage before making

audio connections. As an extra precaution, have the input attenuators turned down during initial power up.

COOLING REQUIREMENTS

ICA Series amplifiers use a forced-air cooling system to maintain a low, even operating temperature. Cooling air is drawn by a continuously variable-speed fan mounted on the back

panel, and exhausts through slots on the front panel. The fan will remain inactive until internal operating temperature rises above 45º C (113º F). Make sure there is enough space around the back of the amplifier to allow air to enter. NOTE: If the amplifier is rack mounted, do not use doors

or covers on the front or back without pressurizing the back of the rack. Whatever type of rack you are using, make sure that heated air can escape freely, and that there is no resistance to the intake of cool air through the back grill. Intake and exhaust air must flow without resistance.

HIBERNATION

™

All ICA Series amps feature Hibernation circuitry. Current draw and thermal emissions are at a minimum when the absence of input signal is sensed for more than a minute. Once signal is present, Hibernation instantly restores the amplifier to normal. Current draw specifications while Hibernation is active are included in specifications under Idle Current Draw.

THERMAL EMISSIONS

The system installer or designer should specify system cooling needs. Refer to the specifications at the back of this manual for specific thermal emissions figures.

INPUT CONNECTIONS

The input connector accepts balanced and unbalanced audio signals. For use with an unbalanced source, tie the inverting (-) input to ground by installing a jumper to the signal ground connection. If the inverting input is left floating, a 6 dB loss in gain will result.

SIGNAL MODE CONFIGURATION

ICA

™

Series amplifiers are configured for Stereo (2-channel), Bridged Mode, or Parallel Mode

operation at the input connector.

To send the same signal to both channels (Parallel Mode), connect the input signal to CHANNEL A via the input connector. Run jumpers from the positive and negative terminals of the CHANNEL A input connector to the respective terminals of CHANNEL B. Both channels then share the CHANNEL A input signal but will operate independently. Speakers are connected as in Stereo Mode.

Bridged Mode converts the amplifier into a single-channel unit with a power rating equal to the sum of both channel power ratings, and at a load rating twice that of the single-channel rating. In Bridged Mode, the channels operate at opposite polarity of each other so that one channel “pushes” and the other “pulls” equally. Signal is connected to the input connector with one jumper connecting the positive (+) terminal of Input A to the negative (-) terminal of Input B, and another jumper connecting the negative (-) terminal of Input A to the positive (+) terminal of Input B. Both channel attenuators (A & B) are used to control signal level, and both must be at the same level, preferably at 0 dB attenuation. The speakers are connected only to the designated “+” output terminals. NEVER

ground either side of the speaker cable when the amplifier is in Bridged Mode as both sides are “hot”. If an output patch panel is used, all connections must be isolated from each other and

from the panel. For ICA Series amplifiers, the minimum nominal load impedance in Bridged Mode is 8 ohms; this is the equivalent of driving both channels at 4 ohms. Driving loads of less than 8 ohms may activate the LFC circuit and may also cause a thermal protect condition. NOTE: Regardless of operating mode, NEVER connect amplifier outputs together!

SPEAKER OUTPUT CONNECTIONS

Speakers are connected using the output barrier strip connectors. Spade lugs, ring tongues or bare wire may be connected to the output barrier strip elements. The barrier strip can accommodate up to two 10-guage wires per terminal. Make sure the amplifier is turned off before you change any output connections or jumpers. Consult the Wire Gauge Chart at the back of this manual to find a suitable wire gauge to minimize losses of power in the speaker cables. Also, make sure that the load impedance is not lower than that rated for the amplifier.

SIGNAL GROUND CONNECTION

Connections at the input connector permit the audio signal ground to be connected or lifted from the chassis ground. When possible, the shield of the signal source connecting cable should connect to the chassis ground. In some cases, however, particularly if an amplifier is being installed in an existing system, this may result in a ground loop. If this happens, connect the shield to the signal ground only. The chassis ground also connects to the AC ground internally. If the cable shield is connected to the signal ground only, it will be clamped to +/- 0.6 V above or below chassis/AC ground.

PROTECTION FEATURES

The ICA™Series incorporates protection features derived from Peavey’s extensive experience with reliability. The amplifiers are ruggedly built from high-quality components and feature comprehensive protection circuits to protect your amplifier from those “real world” occurrences.

CLIP LIMITING

At the amplifier’s full power, or clipping point, the channel gain will automatically be reduced, guarding the loudspeakers against damaging high power and continuous square waves that would otherwise be produced. This is indicated by illumination of the CLIP LED. Normal program transients will not trigger Clip Limiting, only steady or excessive clipping will. Operation is virtually transparent in use and full signal bandwidth is maintained.

LOAD FAULT CORRECTION

™

LFC is an innovative circuit that will instantaneously reduce channel gain to allow the amplifier to operate at a safe level into an abnormal load. LFC activation is indicated by illumination of the LFC LED. Moderate activation of LFC is inaudible in normal use. In addition, if extreme low impedance or a short circuit is encountered during high signal level conditions, the amplifier’s output relay will open.

FADE-IN PROTECTION

This feature operates every time the amplifier is turned on, or after a protect condition. During turn on, the amplifier goes into protect mode and leaves the speaker load disconnected until the amplifier determines that the operating status is normal. The Fade-In circuit attenuates the signal during the initial turn on or protect operation. After relay release, channel gain gradually increases to the attenuator setting to avoid unnecessary stress on the loudspeakers.

THERMAL PROTECTION

If the heatsink or power transformer reaches an abnormally high temperature, the amplifier will protect itself by disconnecting the speaker load until the amplifier returns to a normal temperature. During this time, the PROTECT LED will illuminate, and the cooling fan will operate at maximum speed.

SHORT CIRCUIT

If an output is shorted, the LFC

™

, speaker relay and thermal circuits will automatically protect the amplifier. The LFC circuit senses the short circuit as an abnormal load condition and reduces the channel gain to a safe level for the load. In extreme or severe conditions, the speaker relays will disconnect the load and initiate a power-on start-up sequence.

DC VOLTAGE PROTECTION

If an amplifier channel detects DC voltage or subsonic signals at its output terminals, the speaker relay will immediately open to prevent loudspeaker damage. The PROTECT LED will illuminate as notification of this condition.

SEQUENTIAL TURN-ON / TURN-OFF

The ICA™Series comes standard with remote sequential turn-on. The amplifier front power switch is set to STANDBY. An external direct plug-in power supply unit providing a nominal voltage between 12 to 24 volts DC must be applied to the 4-pin plugable terminal on the rear panel. The ENABLE OUT is connected to the ENABLE IN of the next amplifier. ICA Series amplifiers are bussed or “daisy chained” together in parallel and connected to the DC supply by connecting all 24 V DC+ terminals together and all COMMON terminals together. The first amplifier in the chain requires an SPST closure between its 24 V DC+ terminal and ENABLE OUT terminal to initiate the power turnon sequence and keep the amplifiers in the chain powered on.

INTRODUCCIÓN

Felicidades en su compra de un amplificador de Acústica Arquitectónica ICA

™

(Amplificador de Contratistas Acústicos por sus siglas en Inglés) de Peavey Electronics. Por favor lea este manual con atención, especialmente la seccione de SEGURIDAD en la página 18. Esta contiene información vital para la operación segura del amplificador. Por favor tómese el tiempo de llenar y mandar su tarjeta de registro del producto.

La serie de amplificadores ICA presenta nuevos niveles de valor y flexibilidad nunca antes ofrecidos en el mercado de contratistas. La serie ICA incluye modelos específicamente diseñados para alimentar salidas de 4 ohmios, salidas de 70.7 voltios y salidas de 100 voltios. Las salidas de 70.7 voltios y 100 voltios pueden ser alimentadas directamente, eliminando la necesidad de transformadores. Estos amplificadores cubren casi todas las necesidades de distribución o instalación de poder de sonido imaginables.

Los amplificadores de la serie ICA han sido construidos para que sean durables con materiales de alta calidad para proporcionar la protección requerida a los circuitos y proteger al amplificador de situaciones “de la vida real”.

Si requiere información adicional o asistencia en la operación de este producto, por favor llame al Departamento de Servicio al Cliente de Peavey Electronics o su representante de Peavey local. Las sugerencias que nos ayuden a mejorar nuestros productos siempre son bienvenidas.

DESEMPACAR

Por favor inspeccione el amplificador cuando lo desempaque. Si encuentra algún daño, informé a su distribuidor inmediatamente. Sólo el consignatario puede llevar a cabo un reclamo con el transportista en caso que se hayan experimentado daños durante el flete. Asegúrese de guardar la caja y todos los materiales de empaque. Si alguna vez fuera necesario enviar el producto Peavey Electronics o alguno de sus centros de servicio, o distribuidores, use sólo los materiales de empaque originales.

INSTALACIÓN Y MONTURA

Los amplificadores de la serie ICA son unidades de 2 ó 3 espacios de rack con 15 3/4" (400 mm) de profundidad que se pueden montar en un rack estándar de 19". En todos los amplificadores se proporcionan agujeros al frente para montar la unidad.

INSTALACIÓN BÁSICA

1. Acomode el amplificador en el espacio de rack donde lo quiera instalar, asegurándose de

mantener suficiente espacio de acceso, así como de ventilación de enfriamiento. Para más información, ver las secciones de Instalación y Montura y Requisitos de Enfriamiento.

2. Lleve a cabo las conexiones de entrada necesarias en los bloques de terminales del panel

trasero. Use las conexiones apropiadas para funcionamiento estéreo, paralelo, mono (en puente), y configuración de tierra. Vea la sección de Configuración de Modos de Señal y Módulo de Conexiones de Entrada para más información.

3. Conecte las bocinas o altavoces al módulo de salida. Asegúrese de llevar a cabo las

conexiones correctas para estéreo, paralelo o mono/puente. Vea la sección Conectores de Salida de Bocinas para más información.

ESPAÑOL

4. Lleve a cabo las conexiones de poder, cubriendo las necesidades del amplificador. Vea las

secciones CONECTOR IEC y Requisitos de los circuitos de CA para más información.

5. Gire el interruptor de poder (AC POWER) de tres posiciones a la posición ON y suba los

atenuadores de ganancia (LEVEL) en el panel trasero a los niveles deseados.

CARACTERÍSTICAS DEL PANEL FRONTAL

1. INSTALADOR PARA RACK

Estos agujeros se proporcionan en todas las unidades para su instalación.

2. INTERRUPTOR DE PODER (AC POWER) DE TRES POSICIONES

Un interruptor de poder de tres posiciones se encuentra en el panel frontal. La capacidad de encender secuencialmente de forma remota es estándar. Con el interruptor presionado hacia la posición de afuera, el amplificador está encendido. La posición del medio es apagado y la posición adentro es STANDBY. Cuando se selecciona STANDBY el amplificador puede ser activado por circuitos de encendido secuenciales. Vea la sección Encendido/Apagado secuencial para más información.

3. LED DE PODER

El LED de poder se enciende cuando el amplificador está encendido.

4. LED DE SEÑAL

Cada canal cuenta con un LED de señal que se ilumina cuando el amplificador excede 1 voltio.

5. LED DE CLIP

Cada canal cuenta con un LED de clip que se ilumina en el punto de saturación, e indica que los circuitos internos están reduciendo la ganancia del amplificador para permitir el uso de todo el poder. Vea la sección sobre Protección para más información.

6. LFC

™

LED

Cada canal cuenta con un LED de LFC (Corrección de Carga Fallida, por sus siglas en Inglés). Este LED se enciende cuando el canal del amplificador detecta una carga de condiciones anormales. Los circuitos internos instantáneamente reducen la ganancia del canal para permitir que el amplificador opere a un nivel seguro a pesar de la carga anormal. Vea la sección sobre Protección para más información.

7. LED DE PROTECCIÓN

Si el amplificador acaba de ser encendido o ha detectado una condición fallida, los relays de salida se abrirán, iluminando este LED.

8. SECCIÓN DE ENTRADA

La serie ICA cuenta con conectores de entrada y atenuadores rotativos individuales para cada canal como equipamiento estándar. Las conexiones en los conectores de entrada permiten que la tierra de la señal de audio sea conectada o levantada de la tierra del chasis.

9. CONECTORES DE SALIDA DE PARA CABLES

Se ha proporcionado una sección a la que se pueden conectar cables pelados para bocinas. Estas secciones pueden alimentar hasta 2 cables de medida 10 por conector.

10. Conector de Poder IEC

Un conector de poder IEC estándar está localizado en la parte superior izquierda del panel trasero del amplificador. Se incluye un cable de CA que cuenta con la capacidad de voltaje requerida para operar la unidad.

11. Fusible

Hay un fusible protector de CA que está localizado en la parte superior izquierda del panel trasero del amplificador. Si el fusible salta, presiónelo a su posición inicial para regresar el amplificador a modo de operación normal. Si el fusible sigue saltando, el amplificador necesita servicio. No continúe presionando el fusible, ya que esto puede resultar en serios daños internos además de crear situaciones peligrosas.

12. Interruptor de Encendido Secuencial

La serie ICA

™

viene equipada con encendido secuencial de control remoto activado al seleccionar la posición STANDBY en el interruptor frontal. El amplificador será activado al aplicarle un voltaje entre 12 y 24 voltios CD a la terminal trasera de 4 pins, y al haber conectado la terminal ENABLE al la terminal de +24 voltios CD. Cuando no hay voltaje presente o la conexión ENABLE es abierta, el amplificador se apagará. Otros amplificadores ICA pueden ser conectados en serie (daisy-chain) conectando todas las terminales de +24 voltios CD juntas, todas las terminales COMMON juntas, y conectando las salidas ENABLE OUT a las entradas ENABLE IN del siguiente amplificador. Un conector para este tipo de conexiones es incluido con el amplificador.

13. Rejilla del Ventilador

Un ventilador continuo de CD provee aire fresco al amplificador. Nunca bloquee esta entrada. El ventilador opera únicamente cuando el amplificador requiere enfriamiento.
