Overview:

The  RCF SUB 8004-AS is one of the most powerful 18” subwoofers in pro-sound category.

• Featuring a high power, hypervented 18” woofer, with 4” inside/outside voice coils, this cabinet is designed to deliver a serious amount of low frequency
• Powered by a 1250W digital amplifier module, the SUB 8004-AS can perform in the most demanding situations
• The input board includes volume control, deep/punch switch, high pass switch, phase switch, cardioid, time delay

Features:

• 2500 Watt Peak, 1250 Wat RMS
• 136 dB max SPL
• 30 Hz - 120 Hz frequency response
• 18" Woofer, 4.0" voice coil vented woofer
• DSP controlled Input section with selectable presets
• Delay control
• Baltic birch tour grade cabinet
• Compatible with NXL23-A (stacking)
• Compatible with NXL24-A (stacking)
• Multiple configurations with HDL 10-A and HDL 20-A

Applications:

• Live sound
• Rental
• Portable PA, clubs, ballrooms, live theatre
• House of worship
• Theme parks
• Music playback and sound reinforcement in small and mid-size venues
• Corporate A/V professionals and sound system hire companies

1.) MAIN SIGNAL XLR INPUT (BAL/UNBAL). The system accept female XLR input connectors and line-level signals from a mixing console or other signal source.

2.) SIGNAL LINK XLR OUTPUT. The output XLR male connector provides a loop trough for speakers daisy chaining.

3.) XOVER SIGNAL OUTPUT. The output XLR male connector provides a crossover high passed signal (24 dB/octave) for satellites speakers

4.) INPUT SENSITIVITY. Controls the overall signal level at the input to the power amplifier. The control ranges from + ∞dBu (maximum attenuation) to the –2 dBu – MAX sensitivity (maximum input gain). The centre detent is +4 dBu (nominal level required to drive the amplifier at maximum power

5.) DEEP - PUNCH. This switch provides a DEEP equalisation (flat response down to 30 Hz) or a PUNCH equalisation with a boosted equalisation at 70 Hz

6.) XOVER 90/120 HZ. Provides 24 dB/octave low-pass filtering at 90 Hz if released, at 120

Hz if pressed. The same crossover frequency in high-pass is available from XOVER OUTPUT XLR

7.) TIME DELAY ENCODER. This encoder provides a time delay setting expressed in meters.

8.) POWER INDICATOR. Power on indicator. When the power cord is connected and the power switch is turned on this indicator lights green.

9.) SIGNAL INDICATOR. The signal indicator lights green if there is signal present on the main XLR input.

10.) LIMITER INDICATOR. The amplifier has a built in compressor/limiter circuit to prevent clipping of the amplifiers or overdriving the transducers. When the compressor is active the led is blinking yellow. When the soft clipping circuit is active the LED blinks orange. It is okay if the limit LED blinks occasionally. If the LED blinks frequently or lights continuously, turn down the signal level. The amplifier has a built in RMS limiter. If the RMS limiter is active the LED lights red. The RMS limiter has the purpose to prevent damages thetransducers. The speaker shall never be used with the limit indicator red, continuously. Continuous operation with the RMS protection active can cause damages to the speaker

11.) PHASE SWITCH. This switch reverse the phase of the output signal.

12.) CARDIOID SET-UP SWITCH. This switch provides a special equalisation and delay setting to create a cardioid pattern when the system is used in conjunction with two other sub 8006-AS modules.

13.)AC POWERCON INPUT. RCF SUB series uses a POWERCON locking 3-pole AC mains. Always use the specific power cord provided in the package.

14.) AC POWERCON OUTPUT .  Always use the specific power cord provided in the package.

15.)  POWER MAIN SWITCH. The power switch turns the AC power ON and OFF. Make sure that the sensitivity is set to + ∞dBu when you turn on the speaker
