SAFETY PRECAUTIONS
WARNING:
CAUTION
RISK OF ELECTRIC SHOCK DO NOT OPEN
To avoid fire or electrocution risk do not expose the unit to rain or moisture.
To avoid electric shock, do not open the unit. No user serviciable parts inside. In the case of disfunction, have the unit checked by qualified agents.
Class I device.
MPORTANT:
Clean the front panel filters regularly. Extract the filters removing the
front panel grid unscrewing the screews placed at the sides of the grid. Clean
the filters using water and detergent. Place the grid filter introducing first
the internal side and screwing the screws
General Information
Introduction
The XTR Series devices feature two channel models, ready for rough handling in the touring world. For this purpose, Subamp Series amps implement oversized high efciency regulated power supply with PFC front end to deliver their full performances independently of mains status. This together with oversized high efciency audio power stage, forced front to back cooling through a component- free path with removable front panel dust flters, improved rugged mechanical design with even weight distribution… resulting in: just power, reliability and robustness for your touring gigs!
Main Characteristics
- Dual PFC QuantaPulse™ Regulated SMPS.
- Max. Output: 270V / 70A peak.
- Dedicated design for powerful subwoofers.
- 32/38/44 dB selectable Gain.
- RAM Audio Power Management System.
- Hi Efficiency, Heavy Duty Audio Power section for extreme use.
- Removable front panel dust filters.
- Efficient front to back cooling.
- Industry standard Neutrik® XLR and Speakon® connectors.
Controls: Where and What?
Front Panel

-
Signal attenuation level control
knobs : Permit independent control of each channel’s attenuation. -
PMS: LED indicating PMS in operation
SIGNAL: This LED indicates presence of signal at the inputs. ICL: LED indicating Intelligent Clip Limiter in operation (see page 13). -
Main Power Switch :
Position I: Connects the amplifier’s current feed. Position O disconnects the Power.
Rear Panel

-
Signal Input: Female Neutrik® 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 connectors). -
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 -
Gain Selection Minidips: Gain
Selection minidips 1 and 2: Three positions for 32, 38 or 44dB Gain, (Default setting 32dB). -
Minidips de selección de modo:
with minidips 3 and 4 you chose operation mode: Link or Dua
Installation and Operation
Connections
The Power switch must always be on the “Off” position before plugging the amp
to a properly earthed mains socket. 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.
**Balanced Wiring
**
- Ground
- Signal +
- Signal –
Unbalanced Wiring
- Ground
- Signal
- 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
quarter of the amplifier power is produced.
The amplifiers provides, for each channel, a female XLR Connector (Signal
Input) paralleled to a male XLR to daisy chain several amplifiers with the
same signal line (LINK).
The amplifier can operate on two different configurations: DUAL or LINK. The connections for the three modes are different.
DUAL Channel Mode
**See Figure 3
**
- Set the rear minidips in No-Link position (3 and 4 down).
- Select the chosen Gain (Default setting 32dB).
- Connect the signal lines to the female XLR connectors on all channels.
- Connect the speakers’ lines to the corresponding Speakon on the amp respecting the polarity.
- Use the level control knob on the front panel to adjust each channel independently.
- Each signalling LED group will show its corresponding channel status.
LINK Channel Mode
See Figure 4
- Set the rear minidips in Link position (3 and 4 up).
- Operate as Dual Channel Mode with the signal input linked to another adjacent channel
Troubleshooting
In 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 indicate signal presence.
ICL : The Intelligent Clip Limiter is operating
No Signal: No Input Signal is reaching the amp.
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 unfavourable operating conditions.
- Excessive mains current consumption.
Protection Systems
PMS™ – Power Management System
This is a complete set of protections that monitors the main amp parameters (load status, signal input, temperature, current, etc.) in order to draw from the power supply only the precise amount of current required to maintain safe operation during hazardous or extreme working conditions.
This system controls the amount of power that the amp delivers under three basic circumstances:
- 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.
- When internal temperatures rise to near thermal shutdown point due to unfavourable operating conditions. Here the system takes control, restricting current so as to maintain operational continuity at the precise power level which the amp is capable of withstanding at that particular moment.
- Excessive mains current consumption. This event only occurs either under laboratory conditions (long term sinusoidal signal testing with dummy loads) or, for example, in field applications in conditions of prolonged acoustic howl-round. Here PMS takes control to avoid any damage to the speakers and to prevent the mains breaker from tripping or the fuses blowing
ICL2™ – Intelligent Clip Limiter
The RAM Audio ICL2 is an anticlip system to avoid speaker failure and provide more acceptable sound quality even when clipping occurs. With the ICL2 system you don’t lose the music “punch” but the speakers are kept under control.
SSP™ – SOA Sentry Protection
SOA Sentry protection effectively limiting the power that the amp could deliver into an incorrect load or to a direct short-circuit. This avoids power transistor failure.
FCM™ – Faulty Channel Management
Faulty Channel Management system to avoid entire device shutdown
