Frequently Asked Questions - HD 35A RCF

How to connect the RCF HD 35A speaker?

Use balanced Jack or XLR inputs. Plug the power cord into the IEC connector, then switch ON. Ensure the mixing desk is powered on before the speaker.

What does the flashing Limiter LED mean?

The red Limiter LED flashes when the soft clipping circuit is active. Occasional flashing is normal, but if frequent, reduce the input signal level.

How to use the Flat/Boost switch?

The Flat/Boost switch selects the equalization. 'Flat' is recommended for most applications, while 'Boost' is a loudness contour suitable for background music at low volume.

Which cables to use to avoid interference?

Use only shielded cables for line signals. Avoid running them near mains cables, speaker cables, or equipment generating strong electromagnetic fields.

Can the speaker be suspended?

Yes, use at least two M10 threaded holes on opposite sides. Never suspend the speaker by its handles; they are for transport only.

How to clean the HD 35A speaker?

Use a dry cloth. Do not use solvents, alcohol, benzene, or any volatile products that may damage the surfaces.

What if the Power Status LED does not light up?

Check that the power cord is plugged in and the switch is ON. Ensure the mains voltage matches the rating on the unit. If the problem persists, contact an authorized service center.

What type of fuse should be used?

For 230V supply, use a T 3.15 AL 250 V fuse. For 115V, use T 6.3 AL 250 V. Fuse replacement must be done by an authorized service center.

How to avoid damaging the speaker on power-up?

Always power on the mixing desk before the speaker and set the volume to minimum before turning on. On shutdown, turn off the speaker first.

What does the flashing code of the Limiter LED after initialization mean?

The microprocessor indicates errors: 1-2 flashes = warning, 3-4 = limiting (volume reduced by 3 dB), 5-8 = fault (mute). In case of fault, contact service center.

1. There are numerous mechanical and electrical factors to be considered when installing a professional audio system (in addition to those which are strictly acoustic, such as sound pressure, angles of coverage, frequency response, etc.).

2. Hearing loss

Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is different from person to person and depends on the duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices. When a transducer capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or protective earphones. See the manual technical specifications to know the maximum sound pressure level.

REAR PANEL

1 JACK/FEMALE XLR INPUTS (BAL/UNBAL). The system accept jack or XLR input connectors. These balanced inputs can be used to connect balanced or unbalanced microphones or audio sources at line level. The balanced connector is connected in parallel and can be used to send the audio signal to other amplified speakers, recorders or supplementary amplifiers.
2 LIMITER LED. The amplifier has a built in limiter circuit to prevent clipping of the amplifiers or overdriving the transducers. When the soft clipping circuit is active the LED blinks RED. It is okay if the limit LED blinks occasionally. If the LED blinks frequently or lights continuously, turn down the signal level.
3 SIGNAL LED. The signal indicator lights green if there is signal present on the main input.
4 POWER STATUS LED. This green led is ON when the speaker is connected to the main power supply and the ON/OFF is in ON position.
5 MALE XLR SIGNAL OUTPUT. The output XLR connector provides a loop trough for speakers daisy chaining.
6 VOLUME CONTROL. Adjust the amplifier volume. This control does not affect the "Link" - "Input - Link" output level.
7 FLAT/BOOST SWITCH. Set the flat or boost equalization. "Boost" equalization is a loudness recommended for background music applications, when the system plays at a low level. For all other applications "Flat" equalisation is recommended.
8 INPUT SENSITIVITY SWITCH. Position the switch in LINE to use a line level source (0 dB) or MIC to use a microphone source.
9 IEC AC SOCKET. The IEC AC socket connect the power cord to the socket. (HD 35-A features Powercon input/output main connectors)
10 FUSE CARRIER. Mains fuse housing.
11 POWER MAIN SWITCH. The power switch turns the AC power ON and OFF.

CONNECTIONS

On the back panel you will find all the controls, the signal and current inputs. In case is necessary to change the voltage please call your vendor or authorized RCF SERVICE CENTRE. This operation requires the substitution of the fuse value and is reserved to an RCF SERVICE CENTRE.

At this point you can connect the power supply cable and the signal cable, but before turning on the speaker make sure that the volume control is at the minimum level (even on the mixer output). It is important that the mixer is already ON before turning on the speaker. This will avoid damage to the speakers and noisy "bumps" due to turning on parts on the audio chain. It is a good practice to always turn on speakers at last and turn them off immediately after the show. Now you can turn ON the speaker and adjust the volume control to a proper level.

The amplifiers are equipped with a microprocessor to control the DSP and the amplifier. The correct switch on of the amplifier is ensured by an initialisation procedure; during this test stage the LEDs (Limiter, Signal and Power Status), located on the amplifier module, remain off for approx. 2 sec. At the end of the switch on procedure on the amplifier module the Ready green LED only remains steadily on. In case of severe failure of the speaker, the LED on the front panel flashes several times and on the amplifier module, the Limiter red LED flashes. The speaker switches to "mute".

A 35 mm socket for mounting the loudspeaker on a speaker stand is provided in the bottom of the cabinet. D-LINE speakers MUST be used only with approved rigging hardware.

WARNING: Never suspend D-LINE speakers by there handles. Handles are intended for transportation, not for rigging.

WARNING

FAILURE INDICATION AND SAFETY

The microprocessor is able to signal three different kinds of failure by flashing the "Limiter" red LED on the amplifier panel before the lighting up of the "Power status" green LED. The three types of failure are: WARNING: a non-severe error or auto-ripristinate malfunction is detected and the performance of the speaker is not limited. LIMITATIONS: an error is detected and the performance of the speaker is limited (the sound level is reduced by 3 dB). This does not affect the operation of the speaker since it continues to operate. However, it is necessary to call the service centre to solve the issue. FAILURE: a severe malfunction is detected. The speaker switches to "mute".

FLASHING INDICATION: 1 or 2 >Warning 3 or 4 >Limitation from 5 to 8 >Failure. In case of failure, the "Ready" green LED remains off.

Perform the checks listed below:

• check if the speaker is properly connected to the power supply
• make sure that the power supply is of correct voltage
• check that the amplifier is not overheated
• disconnect the speaker from the mains power supply, wait for a few minutes and connect it again. If after these tests the red "LIMITER" LED is still on, please contact an authorised service centre.
