2 300 W dual channel @ 4 Ω
iD4 / iD7 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 / iD7 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 50 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 / iD7 provide the level of control and audio quality expected in any professional applications. The iD4 / iD7 is 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.

INSTALLATION
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 amplier from mains.
Disconnecting 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 auto mati cally once the power supply has been restored. All amplifier settings prior to the loss of power will be maintained.

INSTALLATION
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 DSPControl application and reduce the onput levels if necessary.
3.5 Signal Inputs
3.5.1 Analog Input
XLR Pin 1 ground
Pin 2 hot (in phase, +)
Pin 3 cold (out phase, –)
Always use symmetrical (balanced) shielded cable to connect the amplifier.
3.5.2 AES Input
The digital AES XLR input accepts any AES / EBU signals (pro or consumer format) in 16 to 24 bit resolution and 44,1, 48, 88,2, or 96 kHz samplig fre­quency. This wide input frequency range of is guaranteed by an integrated sample rate converter (SRC) chip.
3.6 Remote Control / Network Input
The Ethernet Link network connector allows you to access the iD4 / iD7 from a host computer for remote control, firmware update and downloading DSP presets. The iD4 / iD7 is configured by default to use DHCP for automatic IP address assignment in the network. If not desired, this feature can be set through the DSPControl application.
3.7 Power Outputs
3.7.1 SPEAKON® Connection
Both SPEAKON® connectors are connected to channel 1 and channel 2 out­puts. The pin configuration of the SPEAKON connectors is as follows:
SPEAKON® output 2 (View from the back)
SPEAKON® output 1 (View from the back)
Pin 1 + Channel B Output + Pin 1 + Channel A Output +
Pin 1 – Channel B Output – Pin 1 – Channel A Output –
Pin 2 + Channel A Output + Pin 2 + Channel B Output +
Pin 2 – Channel A Output – Pin 2 – Channel B Output –
! WARNING!
SPEAKON® connectors marked with the lightning ash indicate high vol­tages that are potentially life threatening.
Wiring to these terminals requires installation by an instructed person or the use of ready-made leads or cords. Custom wiring should only be made by qualified personnel. To prevent electric shock, do not operate the amplifier with any of the con ductor portion of the speaker wire exposed.
l
NOTE
For reasons of safety and performance, use only high-quality fully in su­lated speaker cables of stranded copper wire.
Use the largest wire size that is economically and physically practical, and make sure the cables are no longer than necessary.
l
NOTE
When connecting speaker cabinets in parallel, always use all the contacts in both SPEAKON® connectors.
If not, this may cause permanent damage to the connectors and may consider­ably reduce performance.

3.7.2 Dual Channel Operation
Two fully independent amplifier channels (“Stereo” – normal operating mode).
Z
min
= 2 Ω for Dual Channel operation
3.7.3 Mono Bridge Operation
One-channel mono bridged operation.
Z
min
= 4 Ω for Mono Bridge operation
In this mode the channel 2 amplifier stage processes the identical input signal than channel 1, but with reversed phase. The channel 2 input signal is not used / ignored. The loudspeaker load must then be connected between the two positive chan­nel outputs (pin 1+ and pin 2+) using a specially configured SPEAKON® con­nector / cable. This effectively doubles the maximum output voltage. But please note that this also doubles the minimum allowed loudspeaker impedance Z
min
.
! WARNING!
In Mono Bridge Operation RMS output voltages can be as high as 230 VAC.
Wiring to the speaker loads must conform to NEC class 3 safety standards or its equivalent that meets all national and local electric codes. All customer specific cables may only be manufactured by qualified suppliers / personnel. All cabling or rewiring work must be carried out by qualified personnel.

Please refer to the separate DSPControl manual for an explanation of the exten­sive Digital Signal Processing (DSP) options and advanced features offered by the remote application.
5.1.1 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.
à
See also chapter 4.5.5 Fuse Protection
5.1.2 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 indicates heavy clip­ping. These LED’s exclusively indicate hardware clipping of the power amplifier stage. Possible internal DSP limitation and compression is not indicated here.
5.1.3 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”
.
5.1.4 ITEM Buttons
The ITEM buttons allow you to navigate trough all parameters which can be set from the front panel. Note that not all parameters can be set from the amplifier user interface. For full and easier access to all settings and parameters please use the DSPControl remote control application. The available parameters are:
Gain

Inside the
“Auxilliary information”
menu you can navigate through the sub menus with the encoder wheel. Note that in this menu the encoder will only work in a round-robin fashion, regardless of the direction you turn it.
l
NOTE
The left (3) MENU button always acts as an ESCAPE / EXIT button in all menus.
5.1.6 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 loading or saving presets) or will allow you to access the parameter’s sub-settings for the Low Pass, High Pass, PEQ, Limiter and Com­pressor.
5.2 Hot Key Functions – Standby
To set the iD4 / iD7 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 / iD7. The standby function can of course also be controlled by the DSPControl remote application.
5.3 Standby Function
The iD4 / iD7 offers the possibility to set the amplifier into standby mode either from the user interface or by the DSPControl remote application. In standby mode the iD4 / iD7 will power down it’s main SMPS, thus saving energy while at the same time staying accessible through the network.
From the amplifier’s user interface this function is accessible through a Hot Key function as described above. Inside the DSPControl remote application you can access this function through the
“Unit”
menu.
An additional feature is the automatic standby function which will set the iD4 / iD7 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 DSPControl remote application through the
“UnitàConfigureàAuto Standby”
menu.
l
NOTE
If the amplier has been set into standby through the Auto Standby func­tion, automatic wakeup will only work if digital AES input signal is applied again.

OPERATION
Applying analogue signal again will not wakeup the amplifier again. When unsing analogue input signal, exiting the automatic standby mode must be done manu­ally through the user interface or the DSPControl remote application. So please consider this carefully before using the Auto Standby function with analogue input signal.
5.4 Power Amp Protection Systems
5.4.1 Clip Limiter / Underimpedance Limiter
The DSP section of the iD4 / iD7 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-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 DSPControl 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.
5.4.2 SOA Protection
Whenever the power transistors leave their Safe Operation Area (SOA), the SOA-protection switches back the rail of the respective channel.
5.4.3 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.
5.4.4 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.
5.4.5 Thermal Protection
There are several sensors inside the amplifier in order to ascertain tem perature data. If a temperature of more than 85 °C is detected at the heat sinks, the input signal on that channel is reduced.

OPERATION
5.5 Mains Protections
5.5.1 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.
5.5.2 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.
5.5.3 Mains Surge Overvoltage Protection
The iD4 / iD7 is fitted with a varistor unit, protecting the SMPS from sporadic surge overvoltages coming from the mains distribution.
5.5.4 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.
5.5.5 Fuse Protection
When driving the iD4 / iD7 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 very dynamic music signals the (short term) input current can still reach very high levels, which can be very demanding for a mains distribution. The operation of the FuseProtect limiter can be seen by short orange or red glowing of the Signal-LED’s in the iD4. In the iD7 the FuseProtect limiter cannot be seen from the signal LED’s.
5.6 Main SMPS Protections
5.6.1 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.
5.7 Fans
The fans mounted in the iD4 / iD7 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.

OPERATION
5.8 Filter Cleaning
The air intake on the front of your iD4 / iD7 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 / iD7 Filter Assembly
Foam filter Front frame Screw
! WARNING!
Turn off and disconnect the amplier 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).

TROUBLESHOOTING
6. Troubleshooting
6.1 Problem: No reaction when switching the amplier 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
6.2 Problem: No sound
If no sound can be heard on the outputs please check following DSP settings (through the DSPControl 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))
6.3 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).
l
NOTE
For this please unplug the amplier from the mains for at least 4 minutes and switch the amplier on again.
If the message still appears after this procedure the fault is permanent and the amplifier requires servicing.
