iD4 amplifiers are fitted with Switched Mode Power Supplies (SMPS), which significantly reduces the weight and size (only 2U) of the amplifier. Using SMPS, the 2 symmetrical supply voltages of the power amplifier are more stable than the power supplies used in conventional amplifiers.

The iD4 has been designed as a powerful two channel amplifier with onboard 64 bit DSP processing. Both amplifier settings and DSP settings can be user adjusted to match a speaker systems specifications. With up to 100 onboard speaker pre-set storage capability, fine tuning of a system or differing systems is fast, easy and strait forward; the user interface is designed to be intuitive allow for quick familiarisation. The combination of both power amplifier and on-board DSP technologies used in the iD4, provide the level of control and audio quality expected in any professional applications. The iD4, a very powerful and complete speaker management system, with optimum flexibility and maximum control and security.

Since some of the externally mounted controls have multiple functions, it is important that users should familiarise themselves thoroughly with the entire range of controls.

3.2 On / Off Switch

The On / Off Switch is a rocker-type switch. It is located on the right side of the front panel. To turn the amplifier on, press on the upper part of the switch. During power up the Clip- and Signal-LEDs from both channels will light up in red for a few seconds. To turn the amplifier off, press on the lower part of the switch.

Amplifier is switched on Amplifier is switched off

l NOTE

This switch does NOT disconnect the amplifier from mains. Discon-

necting the amplifier from the main power supply can only be achieved by disconnecting the mains plug or by an external all-pole disconnection (e.g. a mains / circuit breaker). The mains plug or circuit breaker therefore has to be freely accessible at all times. Disconnect the mains plug from the mains during a lightning storm or when the amplifier remains unused or unsupervised for a prolonged period of time.

The switch initiates start-up by activating the inrush current limiter. As soon as the power amplifier is connected to the mains power supply, a vol tage is supplied to both the line-filter and the fused input of the controllable rectifier. If a power cut occurs while the amplifier is switched on, it will restart automati cally once the power supply has been restored. All amplifier settings prior to the loss of power will be maintained.

3.4 Cooling

The air is taken in from the front and out through the back. It is essential that while the amplifier is running the air is able to circulate around it freely. The efficiency of the cooling will depend on the immediate environment (e.g. an enclosed rack, direct sunlight). If the amp is installed in a case, the open area at the back of the case must be at least 140 cm². This area should be in line with the amplifier.

If this cannot be achieved a forced ventilation system has to be used.

Note that continous high power draw at low load impedance (equal or

lessthanapprox.2,7Ω)candrivethe amplifierintothermallimitation.So

please check the amplifier temperatures on the display or in the DSP control application and reduce the onput levels if necessary.

4.1.1 Signal- / Protect-LEDs (multifunctional)

The Signal-LEDs are illuminated in green when the voltage level at the

outputreachesapprox.4V;thiscorrespondstoapowerof4Wintoa4Ω

load. The channel Signal-LEDs are illuminated red when the amplifier is in Protect Mode (Mute), for example because of persistent DC-voltage at the outputs or overheating. When switching the amplifier on, the Signal-LEDs will also light red for a few seconds while the DSP is starting up (along with the Clip-LEDs). In case the FuseProtect limiter is activated, it is possible that the (green) Signal-LED’s will glow in orange or red colour for short periods of time while the amplifier is playing music.

4.1.2 Clip-LEDs (multifunctional)

The colour of the bi-coloured LED changes between orange and red, depending on the clip intensity. Orange indicates light clipping, red indi-

cates heavy clipping. These LED’s exclusively indicate hardware clipping of the power amplifier stage. Possible internal DSP limitation and compression is not indicated here.

4.1.3 CHANNEL Buttons

The CHANNEL buttons allow to select the channels to make adjustments on. Selectable items are In 1 to In 4 and Out 1 and Out 2 (depending on user and access rights). Note that if channels are linked the settings will always affect both linked channels. In this case the channel selection will display In 12, In 34 or Out 12.

4.1.4 ITEM Buttons

The ITEM buttons allow you to navigate trough all parameters which can be set from the front panel. Note that currently only a small choice of parameters can be set from the amplifier user interface. For full access on all settings and parameters please use the DSP Control remote control application. The parameters are:

l NOTE

The left (3) MENU button always acts as an ESCAPE / EXIT button in all menus.

4.1.6 Rotary Encoder with Push Button

The rotary encoder allows to make swift adjustments of parameters (like for example the Gain settings) by simply turning it in the desired direction. In some menus the push-function of the encoder will act as an ENTER button, for example when selecting / loading presets.

4.2 Hot Key Functions – Standby

To set the iD4 to standby mode simply press both (34) MENU buttons simultaneously for more than three seconds. You will then be asked if you want to switch to Standy Mode. Pressing the encoder knob (without rotating it) will then power down the main power supply of the iD4. The standby function can of course also be controlled by the DSP Control remote application.

4.3 Standby Function

The iD4 offers the possibility to set the amplifier into standby mode either from the user interface or by the DSP Control remote application. In standby mode the iD4 will power down it’s main SMPS, thus saving energy while at the same time staying accessible via network connection.

From the amplifier’s user interface this function is accessible through a Hot Key function as described above. Inside the DSP Control remote application you can access this function through the Hardware menu.

An additional feature is the automatic standby function which will set the iD4 in standby mode if no input signal (analogue and / or AES) is applied for a certain period of time. This delay time can be set individually (or switched off) inside the DSP Control remote application through the Hardware à Configure à Standby Delay menu.

l NOTE

If the amplifier has been set into standby through the auto-standby function, automatic wakeup will only work if digital AES input signal is applied again.

Applying analogue signal again will not wakeup the amplifier. When unsing analogue input signal, exiting the automatic standby mode must be done manually through the user interface or the DSP Control remote application. So please consider this carefully before using this function with analogue input signal.

4.4 Power Amp Protection Systems

4.4.1 Clip Limiter / Underimpedance Limiter

The DSP section of the iD4 offers various limiter and compressor settings, both on the signal inputs and on the signal outputs. Those limiters and compressors can be adjusted and even switched off completely if desired. Disabling the limters is done by setting the thresholds to their highest values.

But in case the amplifier is driven into hardware clip (i. e. when the Clip-

4 OPERATION

LED is glowing orange or red) for longer periods of time, the threshold setting of the output limiter will automatically be reduced temporarily. Note that this is automatically done inside the amplifier and cannot be seen in the DSP control application. This automatic threshold reduction will especially take place at low output

impedances(smaller 4Ω)andhigh outputpowersand shallprevent the

amplifier from being operated in continuous hard amplifier cliping.

4.4.2 SOA Protection

Whenever the power transistors leave their Safe Operation Area (SOA), the SOA-protection switches back the rail of the respective channel.

4.4.3 DC Protection

Each output of the power amp is constantly monitored for persistent DC voltage levels. If the 3 V thresholds are exceeded at any of the outputs, the corresponding channel will be muted. If DC was only detected for a short moment, the amplifier will release mute and work as normal. If DC is detected for longer periods or repeatedly, the amplifier will switch to standby mode and disable the main power supply. If this happens the display will indicate “Error – amp switched off”. In this case, switch off the amplifier for at least 4 minutes and switch the amplifier on again.

4.4.4 Over Current Protection

Over current is permanently controlled in the output stage. There are two limit ing levels of over current depending on output voltage. These limits will be set automatically. This improves reliability without degrading sound quality when driving complex loads.

4.4.5 Thermal Protection

There are several sensors inside the amplifier in order to ascertain temperature data. If a temperature of more than 85 °C is detected at the heat sinks, the input signal on that channel is reduced.

4.5 Mains Protections

4.5.1 Inrush Current Limitation

Within 2 seconds of the amplifier being switched on, the inrush current limiter will increase mains current from nearly zero to nominal value. This value depends on program material, output level and speaker loads.

4.5.2 Mains Over Voltage Detection

Mains over voltage detection is always operative. When the mains voltage exceeds approx. 263 V (220 / 230 V operation) or 134 V (110 / 120 V operation), the amplifier will be switched off. The system will try to restart in intervals and will return with a soft start when the regular mains voltage returns.

4.5.3 Mains Surge Overvoltage Protection

The iD4 is fitted with a varistor unit, protecting the SMPS from sporadic surge overvoltages coming from the mains distribution.

4.5.4 Mains Failure Detection

Mains failure detection is always operative. When the mains supply is interrupted for about 2 mains cycles, the amplifier will be switched off. When the mains voltage returns to a normal value, a soft start occurs.

4.5.5 Fuse Protection

When driving the iD4 at very high output levels over a longer period of time (i.e. several seconds and minutes) the average mains current draw can become very high. In such situations, the FuseProtect limiter will reduce the output signal in order to prevent the external mains breaker from tripping. But this limiter in turn will not affect the output signal on dynamic music signal and short current peaks, thus guaranteeing the full available peak output power. Please note that the FuseProtect limiter only controls the average mains input current, not the short term peak input current. This means that with

4 OPERATION

very dynamic music signals the (short term) input current can still reach very high levels, which can be very demanding for a mains distribution. If active, the operation of the FuseProtect limiter can be seen by short orange or red glowing of the Signal-LED’s.

4.6 Main SMPS Protections

4.6.1 Over Current Protection

Main SMPS (Switched Mode Power Supply) transformer current is continuously monitored. If over current occurs, the main SMPS immediately stops working. Should there be an internal failure, this feature prevents other parts being damaged.

4.7 Fans

The fans mounted in the iD4 operate permanently, but as long as the temperature remains below 40 °C they run at their slowest speed and can hardly be heard. The highest detected temperature from either channel controls the speed of the fans: above 40 °C the speed is increased until it reaches its maximum value.

4.8 Filter Cleaning

The air intake on the front of your iD4 amplifier is fitted with a removable filter system. If the filter becomes clogged, the unit will not cool as efficiently as it should and may result in reduced output levels.

iD4 Filter Assembly

 Foam filter  Front frame  Screw

4 OPERATION

! WARNING!

Turn off and disconnect the amplifier from the mains before removing the front frame.

To clean or replace the filter just slightly unscrew the fixing screw with the help of a 3 mm allen key. The screw will be held back by a small plastic spacer on the back of the frame to avoid losing it. Then shift the front frame slightly to the right. Then you should be able to remove the frame from the amplifier completely (pull gently to avoid any bending of the front frame).

5. Troubleshooting

5.1 Problem: No reaction when switching the amplifier on

If nothing happens when switching the amplifier on (i.e. the display stays totally dark, no message inside the display), please check following points:

Check mains cable and plug Confirm that the AC outlet works by plugging in any other device

5.2 Problem: No sound

If no sound can be heard on the outputs please check following DSP settings (through the DSP control application):

Input source selection Input and output gain settings Input and output limiter settings If digital (AES) input signal is used, please check AES signal source

(samplig frequency, bit resolution and signal quality (long cables))

5 TROUBLESHOOTING

5.3 Problem: Error message: “Error – amp switched off”

This error message indicates an internal error which forced the main power supply (SMPS) to be switched off. This can be caused by:

Detection of permanent DC on the outputs Detection of amplifier stage malfunction (protect) Detection of main SMPS error

You can try to power-cycle the amplifier to reset all amplifier stage detection circuits. This might help in case the DC or amplifier fault was caused by an invalid input signal (e.g. an extremely high frequent or extremely distorted input signal). For this please switch off the amplifier for at least 4 minutes and switch the amplifier on again. If the message still appears after this procedure the fault is permanent and the amplifier requires servicing.
