PowerH SERIES

1.4 Features and Description

The power amp H2500/H5000 is part of Dynacord’s new PowerH SERIES, which marks a milestone in the design and the production of high-performance power amplifiers. The innovative 3-stage Grounded Bridge Class H Topology with “floating” switching power supply unit offers very high and stable

output with extreme high efficiency on an extremely high performance level at minimum weight. PowerH amps are ideal for driving professional touring, high-end Concert-Sound and Pro-Sound

applications.

Next to classical protections, this new design employs the multi-stage ATP system (Advanced Thermal Protection) for the first time, which in most cases prevents the power amplifier from switching off when the temperature exceeds a critical level. The newly designed MCS system (Mains Current Supervision) prevents power amplifier breakdown caused by the activation of the automatic circuit breaker.

For this, among other things, the MCS system uses the highly precise measurement of the RMS value of the actual mains current consumption. Information about the status of the power amplifier and its internal protections is provided on a LC-display. By utilizing the optionally available remote control module that is compatible with IRIS-Net™, this power amplifier additionally offers comprehensive remote monitoring and remote control functions plus a universal 2-channel digital audio controller (DSP) including highly precise FIR-filtering and digital speaker protection algorithms.

1.5 Responsibility of the User

Speaker System Damage

PowerH power amps provide extremely high power output that might be dangerous for human beings as well as for the connected speaker systems. High output voltages can damage or even destroy the connected speaker systems, especially, when the PowerH amplifier is operated in bridged mode. Prior to connecting any loudspeakers, make sure to check the speaker system’s specifications for continuous and peak power handling capacities. Even if amplification has been reduced through lowering the input level controls on the amplifier’s front panel, it is still possible to achieve full power output with a sufficiently high input signal.

Dangers at the Loudspeaker/Power Outputs

PowerH amplifiers are capable of producing dangerously high voltage output that is present at the output connectors. To protect yourself from electric shock, do not touch any blank speaker cables during operation of the power amp.

HF-Interference

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection agains harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or televsion reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

•Reorient or relocate the receiving antenna

•Increase the separation between the equipment and receiver

•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected

•Consult the dealer or an experienced radio/TV technician for help

	Table 2.4: Specifications for the Power Supply Unit

Mains Operation & Resulting Temperature

The following tables allow the determination of power supply and cabling requirements. The power drawn from the mains network is converted into output power to feed the connected loudspeaker systems and into heat. The difference between power consumption and dispensed power is called power dissipation (Pd). The amount of heat resulting from power dissipation might remain inside of a rack-shelf and needs to

be diverted using appropriate measures. The following table is meant as auxiliary means for calculating temperatures inside of a rack-shelf system/cabinet and the ventilation efforts necessary.

The column Pd lists the leakage power in relation to different operational states. The column BTU/hr lists the dispensed heat amount per hour.

2.3 Mains Switch

The Mains Switch on the front panel separates the power amp from the mains. Pressing the Mains Switch starts booting up the power amp. A soft start circuit compensates mains inrush current peaks and thus prevents the automatic cutout of the mains from reacting when switching on the power amplifier. Speaker system switch-on is delayed by approximately 2 seconds via output relays, effectively suppressing any possible power-on noise, which otherwise might be heard through the loudspeakers. MUTE-LED light and the fans are running during this delay.

2.4 Mounting

Front Mounting of the Power Amplifier

PowerH amplifiers have been designed for installation in a conventional 19-inch rack case. Attach the power amp with its frontal rack mount ears using 4 screws and washers as shown in illustration 2.4.

Illustration 2.4: Front mounting when installing the power amplifier in a rack case

Rear Mounting

Additionally securing the amplifier at the rear becomes necessary, if the rack case in which the power amplifier has been installed will be transported. Failure to do so may result in damage to the power amplifier as well as to the rack case. Brackets for securing the power amplifier are supplied. Attach the power amp as shown in illustration 2.5 using the supplied 4 case nuts and screws.

Illustration 2.5: Rear mounting when installing the power amplifier in a rack case

12 Owner’s Manual

Illustration 2.6: H2500/H5000 Ventilation

PowerH SERIES

2.5 Ventilation

As with all Dynacord power amps with fan

cooling, the airflow direction is front-to-rear, obviously because there is more cold air

outside of the rack case than inside. The power

amplifier remains cooler and dissipating the developing waste heat in a specific direction gets easier. In general, setting up or mounting

the power amplifier has to be done in a way that fresh air can enter unhindered at the front and

exhausted air can exit at the rear. When installing the power amp in a case or rack

system, attention should be paid to these details

to provide sufficient ventilation. Allow for an air duct of at least 60 mm x 330 mm between the rear panel of the power amplifier and the inner wall of the cabinet/rack case. Make sure that the duct reaches up to the cabinet’s or the rack case’s top ventilation louvers. Leave room of at least 100 mm above the cabinet/rack case for ventilation. Since temperatures inside of the cabinet/rack case can easily rise up to 40 °C during operation of the power amp, it is mandatory to bear in mind the maximum allowable ambient temperature for all other appliances installed in the same cabinet/rack case.

CAUTION:

Blocking/closing the power amp’s ventilation louvers is not permissible. Without sufficient cooling/ventilation, the power amplifier may automatically enter protect mode. Keep ventilation louvers free from dust to ensure unhindered airflow.

CAUTION:

Do not use the power amplifier near heat sources, like heater blowers, stoves or any other heat radiating devices.

CAUTION:

To ensure trouble-free operation, make certain that the maximum allowable ambient temperature of +40 °C is not exceeded.

For fixed amplifier installations in a device control room that incorporate a central air-cooling system or air conditioners, calculating the maximum heat emission may be necessary. Please also take notice of the information on page 10.

2.6 Groundlift

The ground lift switch allows eliminating noise loops. When operating the power amplifier together with other equipment in a rack case, setting the switch to the GROUNDED position is recommended. Set the switch to UNGROUNDED, when the power amplifier is operated together with appliances with differing ground potentials.

Owner’s Manual 13

PowerH SERIES

2.7 Indication of the Operation Mode

Two LEDs on the power amp’s front panel indicate the currently selected mode of operation. The PARALLEL-LED lights yellow, when the ROUTING switch is set to PARALLEL. The PARALLEL LED does not light, when the switch is set to DUAL. The BRIDGED LED lights yellow, when the MODE switch is set to BRIDGED. The BRIDGED LED does not light, when the switch is set to NORMAL.

2.8 Selecting the Mode Of Operation

ROUTING

The ROUTING switch on the power amp’s rear panel defines how the audio inputs handle the input signals.

DUAL

In DUAL mode, the two channels of the power amplifier work independent from each other. This mode of operation is being used for all 2-channel applications, like stereo or Bi-Amp (active) operation. Using the input level controls on the power amp’s front panel or an optionally available remote control module and IRIS-Net™ allows independently adjusting the channels’ amplification.

Illustration 2.7: Audio signal applied to both input connectors in DUAL mode

PARALLEL

In PARALLEL mode, the inputs of channel A and channel B are directly electrically linked. The audio signal has to be applied to the input connectors (XLR or Phoenix) of channel A. Using the input level controls or IRIS-Net™ to independently control the amplification of the two channels is still possible because only the channels’ inputs are linked. PARALLEL operation is the mode of choice, whenever the same input signal drives multiple power amp channels of a large system installation, e.g. when driving massive bass arrays.

Illustration 2.8: Audio signal applied to input connector A in PARALLEL mode

CAUTION:

In PARALLEL mode, the input signal has to be fed to input channel A only.

14 Owner’s Manual

PowerH SERIES

MODE

The MODE switch on the power amp’s rear panel defines the operation mode of the power amplifier blocks and thus, how a single or more speaker systems have to be connected.

NORMAL

In two-channel operation (NORMAL), both power amplifier blocks work as independent power amp channels and controlling the amplification of each channel separately is possible. How the power amp’s audio inputs handle input signals depends only on the setting of the ROUTING switch.

BRIDGED

In BRIDGED mode, the power amplifier functions as single-channel, monaural power amp. If the switch is set to DUAL (input channels work independent from each other), the audio signal has to be applied to either one of the input connectors (XLR or Phoenix) of channel A while channel B inputs are inactive. With the switch being set to PARALLEL, the audio signal may be fed to either one of the inputs of channel A or of channel B. In BRIDGED mode, the power amp channel A is modulated as usual.In addition, the input signal is internally inverted and applied to channel B. The A and B power amps act in push-pull operation delivering doubled output voltage.

Illustration 2.9: BRIDGED mode

CAUTION:

In BRIDGED mode operation, it is not allowable for the load connected to fall below a value of 4 ohms. Extremely high voltages can be present at the output. The connected speaker systems must be able to handle such voltages. Make sure to completely read and fully observe power rating specifications of the speaker systems to be used and to check them against the output power capacity of the power amp.

SENSITIVITY/GAIN

PowerH SERIES amplifiers can be operated at an input sensitivity of 0dBu as well as at a constant gain of 35dB or 32dB. A correspondingly labeled LED on the power amp’s front panel indicates the respective setting of the sensitivity/gain switch, which is located on the power amp’s rear panel.

NOTE:

If a remote control module is used the sensitivity/gain switch is deactivated and the sensitivity/gain of the amplfier is automatically set to 35 dB.

An Input sensitivity of 0dBu means that with an input signal of 0 dBu (0.775 Vrms), the signal at the power amplifier outputs is at Rated Output Power. This setting is recommended for audio signal sources that deliver a nominal output voltage of 0 dBu. As an alternative, operating the power amp at a constant gain of 35 dB or 32 dB is also possible. Operating all power amps in a setup – even those of different performance classes – at constant gain setting greatly simplifies the adjustment of signal processors. This allows the

Owner’s Manual 15

PowerH SERIES

installer to consider each power amplifier with a gain of 35 dB (or 32 dB) when setting gain structure, independent of the actual maximum output capacity of each individual power amp. Any limiters have to be adjusted to maximum power handling capacity of the loudspeaker components.

Audio Cabling

Input (XLR / Phoenix)

Inputs IN A and IN B are electronically balanced and the SENSITIVITY switch controls input sensitivity. Connection can be established either by using XLRor Phoenix-type connectors, which are connected in parallel. The needed Phoenix-type connectors are supplied with the power amplifier. The pin-assignment of XLRF-type connectors is in accordance with the IEC standard 268.

Illustration 2.10: Balanced connection of input

Whenever possible, using balanced audio signal feeds at the input of the power amplifier is always preferred. Unbalanced connections should only be used if the cables are very short and no interfering signals are to be expected in the vicinity of the power amplifier. In this case, bridging the screen (shielding) and the pin of the inverting input inside of the connector is mandatory. Otherwise, a 6 dB drop in level could result. Please also see illustration 2.11. Due to their immunity against external interference sources, such as dimmers, mains connections, HF-control lines, etc., using balanced cabling and connections is always preferable.

Output (Speakon-type Connectors / Terminals) in Normal Mode

With PowerH SERIES amplifiers speaker connection differs depending on the actually selected mode of operation of the power amplifier blocks, i.e. the setting of the MODE switch on the power amp’s rear panel. In NORMAL mode, the loudspeaker systems can be connected in two different ways: using typical Speaker Systems Cabling or Bi-Amp Cabling.

Typical Speaker System Cabling

The first possibility is to use the two Speakon-type connectors, whereas speakers have to be connected to pins 1+ and 1– of the sockets, see illustration 2.13.

Next to the Speakon-type sockets, conventional speaker terminals are provided as well. The following illustration shows how to connect the speaker systems for NORMAL mode operation.

Illustration 2.14: Speaker connection in NORMAL operation mode, using Terminals

Bi-Amp Cabling

The second possibility for connecting the speakers when the power amplifier is operated in NORMAL mode is to only use the Speakon-type connector CH A and to connect one speaker cabinet to pins 1+ and 1–, as described above and the second cabinet to pins 2+ and 2– as shown in illustration 2.15. Only pins 2+ and 2– of the Speakon CH A connector are assigned. Proceeding like this facilitates the cabling of speaker systems that are used in active 2-way operation (Bi-Amp).

3.1 Volume Control

In DUAL and PARALLEL mode, the level controls CH A and CH B on the power amp’s front panel are used to control the amplification of the corresponding channel. Turning the control to the right increases and turning it to the left decreases the volume. In BRIDGED mode operation, the output volume of the power amp is only controlled by the CH A level control. Any changes in the setting of the CH B level control are ignored.

With an installed remote control module, the level controls CH A and CH B may be deactivated, i.e. controlling the power amp’s amplification is only possible via IRIS-Net™. The Level Controls Off ! indicator on the LC display signals that the controls are deactivated.

CAUTION:

All devices on a specific CAN-BUS must be set to the same baud rate.

MODULE CONFIG/Audio-Input: The currently used audio input is indicated. Pressing the ENTER button opens the Select Audio-Input dialog box, which, by pressing the Up/ Down buttons, allows selecting Analog or AES/EBU inputs. Pressing the ENTER button stores the desired input in memory and the display returns to the MODULE CONFIG menu.

MODULE CONFIG/Power: The power amp’s actual operating status after using the mains switch is displayed.

If standby mode has been activated via IRIS-Net™ and the power amplifier has been switched off using the mains switch, the power amp automatically restarts into standby mode the next time it is switched on by pressing the mains switch. This menu item allows booting the power amplifier out of standby mode, even without IRIS-Net™.

Pressing the ENTER button opens the Set Power dialog box, which allows the selection of On or Standby operating states by pressing the Up/Down buttons. Pressing the ENTER button stores the desired status in memory and the MODULE CONFIG menu reappears on the display.

PowerH SERIES

3.3 Indications

PROTECT

Whenever the PROTECT-LED lights yellow, one of the internal protections has been activated. However, a lit PROTECT-LED does not necessarily mean that the signal path gets switched off. The differentiated protections concept of PowerH SERIES power amps results in several protection circuits being activated one after another, which ensures that under normal circumstances the power amplifier will stay in the safe and stabile operating range. In case the amplifier needs to be switched off to prevent power amplifier and connected speaker systems from being damaged, this is indicated by the PROTECT and MUTE-LEDs being lit simultaneously.

MUTE

The MUTE-LED lights red whenever the power amp’s output signal is being muted, which happens for example during power-on delay of the speaker systems, when switching the input sensitivity, and when manually muting the output signal via IRIS-Net™.

-30dB…LIMIT

Level indication is realized via two vertical LED chains on the power amp’s front panel that individually indicate the actual levels of each channel at -30dB, -20dB, -10dB below full modulation and 0dB as soon as full modulation is reached. 0 dB indication results from comparing the power amp’s internal ratio of input to output voltage, which ensures precise indication of the full modulation limit, even before limiting becomes audible. If the input audio signal is driven above the 0 dB mark, a clipping limiter reliably controls distortion down to a stable rate of 1 %. The red LIMIT-LED has a dynamic brightness control that makes it easy to perceive the degree of limiting applied to the signal.

POWER

The POWER-LED lights green when the power amplifier is on. If the POWER-LED does not light, despite the fact that the amplifier has been switched on, this indicates that the power amp is not connected to the mains, the primary fuse has blown, or the amplifier is in standby mode (the STANDBY-LED lights yellow). The POWER-LED blinks whenever the voltage at the MAINS IN is too high (overvoltage) or too low (undervoltage), which prevents that the power amplifier can be switched on.

STANDBY

The STANDBY-LED lights yellow when the power amp is in standby mode. Standby mode reduces the amp’s power consumption to an absolute minimum. Activating the standby mode is only possible via IRISNet™. Deactivating the standby mode is possible via IRIS-Net™ as well as directly on the power amplifier. For deactivating the standby mode, select Power from the Module Setup menu (see page 29).
