Frequently Asked Questions - W 6000 Ram Audio

How to connect the amplifier in bridged mode?

Select BRIDGE mode (see manual page 9). Connect the modulation signal to the female XLR connector of channel A (or C for 4-channel models). Connect the loudspeakers to the Speakon connectors of channels A or C using terminals +1 and -2. Use the input attenuator of channel A (or C) to adjust the level. Note: the '-' is not ground.

What does the orange PMS LED mean?

The orange PMS LED indicates several possible anomalies: the amplifier is in power-on phase and outputs are temporarily disabled, internal temperature is approaching standby point, or excessive current consumption is detected.

How to adjust input sensitivity?

Sensitivity is adjusted via the detented input signal attenuators on the front panel. Each channel has independent adjustment. The factory gain is 32 dB. Turn the potentiometers to adjust the input level as needed.

What type of XLR cable to use for an unbalanced signal?

For an unbalanced signal, solder pin 1 and pin 3 to ground, and pin 2 to signal. If pin 3 is not connected to ground, a 6 dB loss will occur, reducing output power by 75%.

The amplifier does not turn on, what to do?

Check that the power cable is properly connected and the mains outlet is live (170-265 V AC). Make sure the power switch is in I position. If the blue LED does not light up, consult a qualified technician.

How to update firmware via USB?

Connect a USB cable to the USB connector on the front panel. Use the software provided by Ram Audio to update the firmware. The process is described in the full manual (page 10). Make sure the device is powered on.

What is the maximum output power?

Output power depends on load impedance and operating mode. For precise information, refer to the technical specifications in the manual (page 14). In Dual mode, it can reach several kilowatts per channel.

How to use LINK mode?

LINK mode allows coupling the inputs of two consecutive channels. Use the amplifier as in Dual mode but with the signal input linked to the next channel. Select LINK mode via the front panel (see manual page 9).

What to do in case of overheating?

The TEMP LED lights up if internal temperature is excessive. Check that ventilation paths are not blocked. Reduce input level or load. The PMS may automatically reduce power. Let the amplifier cool down before reusing.

How to reset the device?

For a hardware reset, turn the amplifier off (position O) then on after a few seconds. For a reset of DSP parameters, use the control software via USB. No physical reset button is provided.

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

Installation and Operation

In the event of incorrect connection or misfunctioning, the amp will activate one or more of its LED to warn about the problem.

3.3 Problemlösung

Correct function: SGNL lights to indicate signal presence.

ICL: The Intelligent Clip Limiter is operating (see page 10).

No Signal: No Input Signal is reaching the amp.

Overheating: The amplifier has reached the maximum operational temperature. Most common cause is: the normal 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 unfavourable operating conditions.

- Excessive mains current consumption.

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:

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 current so as to maintain operational continuity at the precise power level which the amp is capable of withstanding at that particular moment.
3.- 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.
