JL AUDIO JL AUDIO JD400/4 400W RMS JD SERIES CLASS-D 4-CHANNEL AMPLIFIER Premium Engineering Utilizing our exclusive NexD™ high-speed switching technologies, the JD400/4 amplifier is engineered to deliver loads of clean power, with excellent efficiency and low distortion. This little guy churns out 100 watts of audio from each of its four channels into 2 ohms (14.4V, 1% THD) and is fully bridgeable, so it can be used as a 3-channel amplifier, or as a 2-channel amplifier producing a whopping 200W x 2 into 4 ohms. The JD400/4’s controls can be found on the input panel of the amplifier, with all speaker and power connections located along the opposite end of the extruded aluminum chassis. Signal processing features include high or low-pass 12 dB / octave filters (defeatable) for each channel pair, with continuously variable frequency selection from 50-500 Hz, and dual-range, differential-balanced inputs capable of accepting line-level or speaker-level signals. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard equipment. Onboard LED-clipping indicators are also included surrounding each input sensitivity control. This convenient feature lets you set your amplifier’s input sensitivity, quickly and accurately, without special equipment. You will also find a set of buffered, pass-through preamp outputs on-board, so you can pass signals to another amplifier. NexD Switching Technology Let's get a little nerdy... A traditional PWM switching amp design uses a fixed switching frequency and varies the pulse width based solely on the audio input signal to the pulse modulator. This basic approach assumes some ideal conditions, like a rock-steady power supply, that do not necessarily occur in a real, in-car installation. Power supply sag with signal causes distortion at all power levels with these designs, even well below clipping. The cure for this is feedback (a corrective signal sent back to the input side), but this becomes impractical as the audio frequency increases, making it a good solution for band-limited (subwoofer) amps, but not for full-range amplifiers. Taking the above into account when designing the NexD™ subwoofer amplifiers, we have taken the simple fixed PWM approach and enhanced it with a very high switching frequency: 240 kHz, which is about 4x higher than most Class D subwoofer amplifiers. This pushes the amplifier's bandwidth to at least 500 Hz with minimal distortion and improves efficiency, while keeping typically bulky circuity more compact. Your subwoofers will reward you with tight, rock-solid bass performance. For the full-range NexD™ amplifiers and channels we applied a variable, ultra-high speed version of the NexD™ technology (switching at well over 400 kHz). In these designs, a self-oscillating modulator with "feed-forward" sends information about the instantaneous power supply voltage to the modulator, combining this with the input signal to cancel out any distortion due to supply voltage fluctuation. This reduces distortion prior to applying feedback, simplifying the overall feedback loop design. Differential-Balanced Inputs Today’s vehicles are equipped with sophisticated electronics capable of generating noise and interference that can intrude into the audio path, ruining the listening experience. Most audio equipment uses single-ended, ground-referenced RCA jacks to receive audio signals. This means that the RCA shield is connected directly to the signal ground. This is a simple, cost-effective input design that works well for short runs in noise-free environments. In noisier environments, this method cannot reject the common mode noise that could be on both RCA conductors (shield and center conductor). By having more than one chassis-grounded RCA shield on a device, single-ended input designs are also more susceptible to ground loops. If noise is present on both conductors while the shield is connected to ground, the input amplifier will amplify the noise relative to the grounded RCA shield. When there are multiple RCA connections or any other conductors subjected to a magnetic field, this will cause a difference in potential across the RCA loop to be amplified at the grounded RCA as noise (a classic ground loop). JL Audio’s Differential-Balanced Input circuits measure the center pin of the RCA connection relative to the RCA shield, even when the shield is not connected to ground, and even when the voltages at both conductors are moving relative to ground. Because both the center conductor and the shield see high impedance to ground at the input, a ground loop cannot be formed, as there is no current flow to induce a voltage as noise. This works equally well with differential-balanced, or unbalanced signal sources, making this input architecture compatible with all standard car and marine audio equipment, using standard, unshielded, twisted-pair RCA cables. No special cables are required, unlike the fully balanced connections used in professional audio. Another benefit of the Differential-Balanced Input design is that it easily accepts low-level and high-level signals from a variety of factory head unit outputs and amplifiers, including single-ended “ground referenced” sources, as well as Balanced or Unbalanced “Bridged or BTL” sources. This eliminates the need for Line Output Converters (LOCs) in most installation scenarios. The obvious question is: “Why don’t all car audio amplifiers use Differential-Balanced Inputs?” The answer is simple: it costs more. Executing a proper differential-balanced input section requires more components and better quality components than a basic single-ended design, so you generally won’t find them on less expensive amplifiers.

The VXi amplifier ecosystem is designed to be very flexible, offering users almost limitless combinations of amplifiers and channel architectures, along with the amazing power of its integrated DSP technology. VXi-HUB is an accessory designed to simplify the control of a networked amplifier system, while greatly easing the setup process, by allowing all amplifiers to appear in a single TüN™ software session. VXi-HUB performs two distinct functions as part of a system employing two or more VXi amplifiers: data networking and digital audio distribution. Data networking is the primary function of the VXi-HUB, permitting a network of VXi amplifiers to respond to synchronized commands from a single DRC controller (DRC-100, DRC-200 or DRC-205, all sold separately). These commands can include Master Volume, Subwoofer Level, Fader, Zone Level and Preset Selection. The VXi-HUB also enables the networked VXi amplifiers to be tuned from within a single TüN™ software session, allowing the user to quickly switch between amplifiers during the tuning process, without disconnecting and connecting multiple cables. For data networking purposes, the VXi-HUB is equipped with one Master and five Slave JLid-COMM connections, permitting the networking of up to six VXi amplifiers using standard CAT5e cables (one master amplifier and five slave amplifiers). For more complex systems, two VXI-HUBs can be daisy-chained to create a network of up to ten VXi amplifiers (one master amplifier and nine slave amplifiers). VXi-HUB also includes a dedicated JLid-COMM accessory port to allow the connection of the optional VXi-BTC Bluetooth® Communicator (sold separately). This accessory enables convenient wireless setup and tuning of the entire amplifier network using a compatible iOS® or Android® device with TüN™ Mobile or TüN™ Express apps. The secondary function of the VXi-HUB is to distribute synchronous optical digital audio signals to the networked amplifiers, avoiding the delays associated with handing digital signals off through a chain of amplifiers. The optical digital audio output of a source unit connects directly to the VXi-HUB’s Optical Audio Input, which then distributes synchronous digital audio to the amplifiers from its five Optical Outputs. VXi-HUB handles S/PDIF signals up to 24 bits/192 kHz. For ease of connection, the VXi-HUB is powered via the JLid™ connection to VXI amplifiers and requires no separate power or turn-on wiring. FEATURES: JLid-COMM Connections: 1 Master Input / 5 Slave Outputs / 1 Accessory Port Optical Audio (S/PDIF) Connections: 1 Input / 5 Synchronous Outputs 3-way Configuration Switch: Standalone / Primary / Secondary Amp Identifier Status LEDs Powered via JLid™ connection to VXi amplifiers
