1.2 Main Characteristics

SIGNAL: This LED indicates pres- ence of signal at the inputs. TEMP: This LED shows tempera- ture protection is active. PMS: LED indicating PMS in opera- tion (see page 13) ICL: LED indicating Intelligent Clip Limiter in operation (see page 13). Main Power Switch: Position I: Connects the amplifier's current feed. (Blue LED on). Position O disconnects the Power. Position II (optional): Stand-by Mode. The Amp's Power is activated remotely via Ethernet. (Amber LED). Display: See page 10. USB Connector for firmware upgrade and optional DSP control.

XLR Connectors for the amplifier’s signal input. Signal Link: Male Neutrik

XLR Connectors for daisy chaining input signal to other amplifiers (parallel connected to female input connec- tors). Speaker connectors: Neutrik

Speakon to connect the speakers. Mains Power Cord: to connect the amplifier to the mains network. The colour code is: Blue: Neutral Brown: Live, single phase Yellow-green: Protective Earth

3The Power switch must always be on the “Off” position before plugging the amp to a properly earthed mains sock- et (170-265V AC). The colour code is: Blue: Neutral Brown: Live, single phase Yellow-green: Protective Earth The input signal fed to the amplifier can be either balanced or un-balanced. The drawing below describes both ways to wire an XLR connector for the purpose. Balanced Signal: Connect pin 1 to Ground, pin 2 to Signal + (hot) and pin 3 to Signal - (cold). Unbalanced Signal: Connect Pin 1 to Ground, pin 2 to Signal and pin 3 to Ground. Important!: If a connection is done with a un-balanced line and pin 3 on the XLR is not connected to ground, a 6 dB loss occurs in the line and only a quar- ter of the amplifier power is produced. The amplifiers provides, for each chan- nel, a female XLR Connector (Signal Input) paralleled to a male XLR to daisy chain several amplifiers with the same signal line (LINK).

6Installation and Operation Installation et mise en service The amplifier can operate on three dif- ferent configurations: DUAL, LINK or BRIDGE. The connections for the three modes are different. See Figure - Set the Amplifier Mode to “DUAL”. - Select the chosen Gain (Default set- ting 32dB). - Connect the signal lines to the female XLR connectors on all channels. - Connect the speakers’ lines to the cor- responding Speakon on the amp respecting the polarity. - Use the level control knob on the front panel to adjust each channel indepen- dently. - Each signalling LED group will show its corresponding channel status. See Figure - Operate as Dual Channel Mode with the signal input linked to another adja- cent channel. See Figure - Set the configuration mode to “BRIDGE” (see page 9). - Select the chosen Gain (Default set- ting 32dB). - Connect a signal line to input female XLR Channel “A” (or Ch-C in 4 chan- nel models). - Connect the speaker line to the Channel A Speakon (or Ch-C in 4 channel models) wired to +1 and -2. In this way pin +1 is positive. - Use Channel-A (or Ch-C in 4 channel modes) control knob to adjust the amp’s output. - The signalling LED groups will show the single channel status. WARNING! The “

Main Screen: shows the current preset name (“G32dB- Dual-UnLink” as default), and the channel attenuation. As an option you can show the output VUmeter. The “M” appears at the top right corner if the preset has been changed from the last load. You can change each channel amplifier level turning the encoder knob for each channel. Amplifier Setup: You access to the Setup Menu, where you can change parameters as Inputs Link, Gain, Bridge Mode... Also you can change the preset and limit the access using a Password. See Amplifier Setup section on next page for more details. Channel Temperature: Show the percent of maximum temperature for each channel. When you are near the 100% the PMS system limits the power output to avoid reach the overheating protection. Display Mode: Change between Channel Attenuation.or Vu meter mode in the Main Screen. Operating Time: shows the amplifier total time operation. Firmware Version: shows the Amp Control firmware ver- sion. You can upgrade it using the USB port. Menu navigation: to access to the Menu screen you have to press the CH-A encoder knob from the Main Screen. Turning the CH-A encoder knob you access to the different options. When you press the CH-A encoder knob you start the Edit mode (only for some options), and a “E” blinking letter appears at the top right corner. Using the four encoder knobs you can change the different options. Pressing another time the CH-A encoder knob you finish the Edit mode, and return to the Menu screen. The last menu option is Exit to return to the main screen or Exit + Dial Lock to protect the encoder knob from any unwanted action. If you use this option you can unlock the system pressing the CH-A knob for 5 seconds. If you need to limit the access to the configuration you can define a password from the Password Manager in the Amplifier Setup section. The Menu development are the next: 3.2 ConfigurationAmplifier Setup: when you are in the Main Menu and access to the Amplifier Setup section, you can change different amplifier parameters, change the current preset and protect the access using a password. The Menu development for this section is the next: Amplifier Gain [dB] 32dB 32dB 32dB 32dB Amplifier Mode

Inputs Link IN-A IN-B IN-C IN-D ICL Clip Limiter Enabled Attenuators Link Disabled Preset Manager Load Save Del Rest Password Control Enabled Installation and Operation Preset Manager: you can change quickly the amplifier preset configuration. To access to any option you have to enter in Edit mode (pressing CH-A knob) and turn the corresponding encoder: CH-A for Load, CH-B for Save, CH-C for Delete and CH-D for Restore default. Select a preset number from 0 to 9. Inputs Link: you can Link the input signal to the next chan- nel. Enter in Edit mode and turn the CH-B, CH-C or CH-D knob to link the input to the previous channel. WARNING! You have to remove the input connector of the linked channel! Amplifier Gain: you can change independently the amplifier gain for each channel from 26dB to 38dB (0.5dB steps). Enter in Edit mode and use the corresponding channel knob to modify it. Amplifier Mode: it configures the amplifier in Dual or Bridge mode. In Edit mode use the CH-A or CH-C channel knob to change the option. Attenuators Link: you can link all attenuators to modify the output level for all channels simultaneously. When you change this option to Enabled, you modify the attenuation for all channels using any channel knob. ICL Clip Limiter: you can turn on or turn off the ICL Clip Limiter for all channels. We recommend to you to work with this option enabled to avoid any damage to the speakers. Password Control: you can define a password to prevent any modification of the amplifier configuration. When you turn on this option, you have to introduce a password using the four knob encoders, and confirm it. After that, you need to introduce this password each time you want to modify the amplifier configuration. There is a generic password which you can use to disable the Password Control, it is: 5 5 5 5 11In the event of incorrect connection or misfunctioning, the amp will activate one or more of its LED to warn about the problem. Correct function: SGNL lights to indi- cate signal presence. ICL: The Intelligent Clip Limiter is ope- rating (see page 10). No Signal: No Input Signal is reaching the amp. Overheating: The amplifier has rea- ched the maximum operational tempe- rature. Most common cause is: the nor- mal air flow is blocked, accumulated dirt, dust or object leaning against the grill. Check and clean periodically. PMS: Several causes can trigger this LED, most common are: - The amplifier is in power-on sequence, where output is inhibited until the amp circuits are ready to operate. - The internal temperatures rise to near thermal shutdown point due to unfa- vourable operating conditions. - Excessive mains current consumption.

This system controls the amount of power that the amp delivers under three basic circumstances: 1.- The power-on sequence, where output is inhibited until the amp circuits are ready to operate. This routine is repeated at every restart, not just when the power switch is activated. 2.- When internal temperatures rise to near thermal shutdown point due to unfavourable operating conditions. Here the system takes control, restricting cur- rent so as to maintain operational continu- ity at the precise power level which the amp is capable of withstanding at that par- ticular moment. 3.- Excessive mains current consumption. This event only occurs either under labora- tory conditions (long term sinusoidal signal testing with dummy loads) or, for example, in field applications in conditions of pro- longed acoustic howl-round. Here PMS takes control to avoid any damage to the speakers and to prevent the mains break- er from tripping or the fuses blowing. The RAM Audio ICL2 is an anticlip system to avoid speaker failure and provide more acceptable sound quality even when clip- ping occurs. With the ICL2 system you don't lose the music “punch” but the speakers are kept under control. SOA Sentry protection effectively limiting the power that the amp could deliver into an incorrect load or to a direct short-cir- cuit. This avoids power transistor failure.
