SPL Audio Crossover Mk2 Active Analog 2-Way Crossover for Pro Audio and Hi-Fi - Black

The second generation SPL Crossover Mk2 features even more crossover frequencies and an extended range of functions – making it the best and most versatile SPL crossover ever. The perfect integration of bass loudspeakers or subwoofers can be difficult. There are almost only digital crossovers for this purpose. But who wants to convert back to digital in an analog high-end playback chain? The analog Crossover Mk2 sets the crossovers anew and rewards with outstanding listening pleasure – thanks to the SPL VOLTAiR technology.

CROSSING OVER

The Crossover Mk2 is divided into two sections: The LOW PASS section for the bass loudspeaker or subwoofer (mono or stereo) and the HIGH PASS section for the top/main speakers. The crossover frequencies for the LOW PASS and HIGH PASS can be set individually from 20 Hz to 3,6 kHz.

With the respective three-position switch X-FREQ, the frequency range for the LOW PASS or HIGH PASS can be pre-set. The following three options are possible:

• Switch position, top – 1,5 kHz to 3,6 kHz
• Switch position, center – 300 Hz to 700 Hz
• Switch position, bottom – 50 Hz to 120 Hz

The X-OVER | Hz switch features six switching positions. This switch is used to pre-set the crossover frequency of the LOW PASS or HIGH PASS. Depending on the pre-selection made with the X-FREQ switch, 18 different crossover frequencies can be set. The slope of the LOW PASS respectively HIGH PASS can be switched from 12 dB to 24 dB with the ROLL-OFF switch. In addition, there is also a low-cut filter. This filter frees both paths, the LOW PASS and HIGH PASS, from unwanted frequencies below 20 Hz. This means that the power amplifier does not have to amplify inaudible low frequencies and the loudspeaker is discharged.

IN PHASE

Audio signals should come from the top speakers and bass loudspeakers or subwoofers in phase. The Crossover MK2 offers variable phase control for this purpose. The three-position toggle switch PHASE can be used to activate phase control. The dedicated control is used to establish synchronization. If the toggle switch PHASE is in the top position (VAR 0°), a value between 0° and 180° can be set using the control. If the toggle switch PHASE is in the top position (VAR -180°), a value between 0° and -180° can be set via the control, thus allowing a control range of 360° If the phase control is not required, it can be switched off (OFF) and thus disappears completely from the signal path.

BALANCED OR UNBALANCED

Gold-plated RCA and XLR sockets are available as connections for each stereo input and stereo output. This allows the Crossover Mk2 to be integrated into any set-up without the need for additional adapters. On the output side, the signal is always present at the RCA and XLR outputs. On the input side, the INPUT switch is used to switch between the XLR and RCA inputs.

EVERYTHING UNDER CONTROL – AMP CTL

The standby mode for up to four devices with 12V trigger input can be switched on and off via AMP CTL, together with the Crossover Mk2 (AMP CTL Out). This is especially useful for connecting power amplifiers. But also the standby mode of the Crossover Mk2 itself can be switched on and off by a preamplifier, such as the Director Mk2, Elector or the Phonitor x, via AMP CTL (AMP CTL In).

THE VOLTAIR TECHNOLOGY

The 120V technology is SPL's reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In SPL's Professional Fidelity series, this unsurpassed technology is referred to as VOLTAiR technology.
