EF Powered Series

It was not easy creating a new élite series following the success of the ground breaking older élite line. Our designers stepped up to the task and delivered something not only
new, but even more ground breaking! The designers chose the iconic élite EF500P as the benchmark for sound quality, then they implanted 1200 watts of bi-amped power using advanced digital signal processing. The EF12P, EF15P and the EF215P models  use a 1200 watt amp and the EF10P uses a500 watt lower power version. A  Bluetooth™ control was added for increased versatil- ity. Finally, they designed cabinets that can handle and deliver the power and sound quality expected by our faithful  sers. With this type of power and versatility the EF-Series powered cabinets are already setting a new standard for active loudspeakers.

Note: The lower power EF10P uses the same technology as the EF12P, EF15P or EF215P but due to the drivers and physical package using higher power was not feasible.

Features

• Ultra-clear audio reproduction throughout the whole bandwidth
• High efficiency, high tech, 1200 and 500 watt bi-amped power modules
• Superior DSP processing with component protection
• True 3-inch Titanium diaphragm horn driver (1-inch on EF10P)
• Low distortion and high power-handling 10, 12 and 15-inch woofers
• Master Level control (cabinet level adjustment)
• Multi-input source mixer with Combi-Jacks (XLR + 1/4-inch TRS hybrid)
• Line input with Combi-Jack (XLR + 1/4-inch TRS hybrid) and 1/8-inch TRS inputs*
• Direct microphone input with level control and phantom power
• Combi Jack (XLR + 1/4-inch TRS hybrid) input and XLR output for easy Linking
• Four EQ modes including a Bluetooth™ adjustable user mode
• Recessed Mixer panel
• Integrated flying hardware (1/4-20 inch threaded holes)
• Ultra strong plywood cabinet and a tough, full-length metal grille
• EF12P REV1 and EF15P REV1 use RCA connectors instead of an 1/8-inch connector for Channel 1

Power and Versatility

The élite EF-Series powered cabinets are bi-amped full-range loudspeakers with built-in two channel mixers. Using Class D switching technology the overall efficiency of the amplifiers have been greatly improved over other designs. The low frequency amplifier used for the woofer in the EF12P, EF15P and the EF215P delivers over 900 watts (400 watts for the EF10P). The amplifier for the high frequency amp uses three-tier linear technology and is rated at 300 watts (100 watts for the EF10P).
This Class H amplifier drives the titanium diaphragm horn drivers helping to reproduce clean transients while keeping up with the high output of the woofers. The combination of Class D and Class H amplifier technologies used on the élite EF-Series powered cabinets help keep distortion to a minimum while reducing the need for  massive heat dissipation. In fact, to a level low enough to eliminate the need for heavy heatsinks. The advantage of this unique combination of three-tier and Class D  amplification has reduced extraneous heat to the point that an EF-Series powered cabinet can easily be used in almost any orientation (close to walls, floors and in close arrays with multiple cabinets). Competitive active loudspeakers (with large finned heatsinks) typically need to be operated vertically and with plenty of clearance to ensure proper ventilation and heat dissipation. Having greater flexibility with the orientation of the enclosure makes the EF-Series powered cabinets ideal for flying in clusters and point-source concert sound systems. This all works because  Yorkville’s designers took extra care making sure that in tight clusters overheating would not be an issue.
As a bonus, the élite EF-Series powered cabinets have a built-in audio mixer allowing microphones and/or  line sources to be used directly. Additionally, the Link system llows additional powered cabinets to be driven from a single source (up to a maximum of 16 EF-Series powered cabinets).

Note: a maximum of 3 mixers can be used when Linking EF-Series powered cabinets USER Tip: When a pair of EF-Series powered cabinets are Linked you can use both mixers integrated on each cabinet. This allows you to have up to two microphones and two line inputs.
As mentioned, our active cabinets can be linked together, one limitation is a maximum of three ‘mixers’ can be active at any one time. This means up to 3 Mic sources and 3 line sources are available in an array of three or more cabinets. The microphone inputs have equalization and high pass filtering designed for vocal applications.
The Master level control is used to adjust the levels of individual powered cabinets. This is invaluable in applications where large numbers of cabinets are used such as in clusters or in trade show applications (or when EF-Series powered cabinets are used as repeater cabinets or for side-fill).
To make it easier to add subwoofers to the EF-Series powered cabinets a 100 Hz high pass filter can be activated. This allows the cabinets to be used more efficiently with almost any active subwoofer.

1. Configuration
   EF-Series powered cabinets can be used stand-alone or in multiples by using the Link connectors. The built-in mixer has a microphone input and two (combined) ¼-inch inputs for line sources such as CD players sources (optimized for CD, laptop computer or a tablet/phone audio source). An external mixer can be used by disabling the internal mixer. Advanced signal processing is used to give maximum performance at all levels. There’s a switch to provide a low frequency roll off if you’re going to use the EF-Series powered cabinet with a subwoofer.

2. Power Switch & Mode LED
   The AC power switch on the rear panel turns the power On or Off. The Mode LED turns on to indicate power is supplied to the unit.
   Note: When Linking cabinets, if one in the chain is turned off, some hum or buzz in the other cabinets may be audible.

3. Limit LED
   There are separate limiters for the woofer and horn amplifiers, this LED indicates operation of either limiter. The amber LED indicates that the cabinet is operating at full power and the limiter(s) are actively reducing the signal level. Operation into slight limiting is acceptable as long as the clip light is flashing and not constantly illuminated.
   Note: The Limit LED does not indicate low frequency processing action.

4. Clip LED
   The red Clip LED indicates that the signal level is excessive and is causing distortion. To reduce clipping, turn down the mixer levels and/or the Master Level controls.

5. Main In / THRU (LINK)
   The Main In / Thru (Link) connectors allow additional powered cabinets to be driven from a single source. You can Link up to 16 EF-Series powered cabinets!
   The Link jacks are also the correct input to use when driving the EF-Series powered cabinets with an external mixer.
   Tech Note: The Link jacks operate at line level (+4 dBu) to achieve full power. When operating from signals that are not as strong, use the Line inputs of the first cabinet in the chain. The Link jacks are high quality balanced inputs with very good common mode (hum) rejection. To ensure maximum hum rejection, the proper balanced cables must be used.
   User Tip: Jacks marked Link Output are connected in parallel with the Link Inputs and are provided for convenience to connect downstream cabinets. Link inputs may also be used as outputs and Link Outputs may be used as Inputs.
   Note: A maximum of 3 EF-Series Control Panel mixers can be used when Linking EF-Series powered cabinets.

6. Mixer On/Off
   This switch turns the internal mixer ‘on’ or ‘off.’ When the Mic or Line inputs are used, this switch must be set to the ‘on’ position. If these inputs are not being used, the mixer should be turned ‘off,’ this will help prevent the mixer from contributing noise to the system. The internal mixer should not be used when a source other than another EF-Series powered cabinet (or similar) is connected to the LINK jacks. Remember, a maximum of 3 mixers, in a chain of cabinets, should be used! A much larger number of cabinets may be used with the mixers disabled on the additional cabinets.

7. Line Input
   Input
   The Line inputs allow line level sources such as digital media players (laptops, tablets or smart phones) and CD players to be connected. A Combi Jack (XLR + 1/4-inch TRS hybrid) and a 1/8-inch TRS jack help provide great versatility. The 1/8-inch TRS input (RCA on REV1) is set up to blend stereo sources into mono. The Line input is also balanced to help reject unwanted hum (when balanced cables are used).
   Note: A microphone may be connected to Channel 1’s Combi-Jack but will have lower gain compared to Channel 2’s Mic input (Phantom power is also NOT available for this input).
   Tech Note: Unbalanced operation – When connecting an unbalanced source to the balanced inputs as on an EF-Series powered cabinet, the best chance for hum rejection is made by running a balanced cable from the source to the input. The return connection should be connected to ground at the unbalanced plug. The EF-Series powered cabinet does not connect AC power ground directly to the input signal ground.
   Control
   The Line control adjusts the input volume level of devices plugged into the Line input.
   Note: You can use the Combi-Jack and 1/8-inch (RCA on REV1) Line level inputs simultaneously but the relative volumes need to be adjusted at the source.

8. Mic Input
   Input
   Any standard microphone may be connected to the Mic input. If your microphone requires Phantom power, it is built-in (some condenser microphones, that don’t have batteries, require an input with Phantom power).
   Control
   The Mic control adjusts the volume level for the Mic input.

9. Master Control
   This control adjusts the level of the individual EF-Series powered cabinet. When Linking multiple cabinets use this control to individually adjust the relative volumes of each cabinet.
   Note: The Master control is designed to be used in the 12 o’clock (middle) position, only minor adjustments are recommended.

10. Mode Selector
    The Mode Selector applies specific EQ and tone settings for the EF-Series powered cabinet effectively custom tailoring your EF-Series powered cabinet for any environment.
    Club: Boosted bass and enhanced highs make this mode ideal for music playback.
    Concert: Allows instruments and vocals to be equally and naturally reproduced which is best for live performance.
    Vocal: Shaped response specifically for the human voice range ensures vocal intelligibility.
    User: Flat by default, can be customized by a user through the Yorkville app with a maximum of five different parametric equalization points with adjustable boost, cut and Q.

11. Sub Switch
    For operation with a subwoofer, the Sub switch shuts off the low frequency boost and filters out signals below 100 Hz. This switch only affects the signals to the internal amplifier and does not affect signals going out from the internal mixer, or to signals passing through the Link connections.

12. Bluetooth™ Control
    This control enables or disables the Bluetooth™ connection between a tablet or a smart phone using the Yorkville App. Pressing the Bluetooth™ button for more than 4 seconds resets the EF-Series powered cabinet to factory settings.

13. Faults and Internal Fuse
    Even in extreme operating conditions the mains fuse should never blow. A blown fuse generally means that excessive mains voltage has been applied or there’s a serious fault with the unit. Self re-setting thermal switches are built into the power transformer. These will not trip even under the most extreme operating conditions and are provided only for safety reasons.
