SPL Active Analog 2-Way Crossover - Silver
Additional Photos:
The SPL Crossover is a high-end active analog 2-way crossover that will perfectly team up your subwoofer(s) with your top speakers. You can tune crossover frequencies, align the phase response and set levels all in the analog domain.
VOLTAiR technology is proprietary 120V rail technology used in the Professional Fidelity series. The Crossover uses this technology throughtout and makes it an outstandig device in terms of dynamic range, signalto-noise ratio and headroom. It delivers an exceptional sound experience with invincible serenity, transparency and realness.
Crossing Over
The crossover is divided into two section: The Low section for the bass loudspeaker or subwoofer (mono or stereo) and the Mid-Hi section for the top/main speakers. The crossover frequencies for Low and Mid-Hi can be set individually from 50 Hz to 120 Hz in 6 positions.
In the LOW section you control the crossover frequency, the level, the phase of the LOW section. You also select whether your playback system has a single subwoofer or two subwoofers. The Low filter has a slope of 24 dB per octave. The slope of the MID-HI filter can be switched from 12 dB (Butterworth) to 24 dB (Linkwitz/Riley).
One or two?
If you want to connect two bass loudspeakers or subwoofers (one for L and one for R), this switch should be set to stereo.
If you only use one bass loudspeaker or subwoofer, switch to mono. The crossover creates a mono signal of the Low frequencies and outputs it to both Low outputs (L + R).
On or off?
If you prefer to run the top/main speakers full-range, you can switch off the MID-Hi filter.
Low Cut Filter
With the Low Cut filter all frequencies below 20 Hz can be filtered out with a 6dB roll-off. This way, no inaudible low frequencies get into the power amplifier, which relieves it a lot.
As long as you're having fun
The playback volume of the bass loudspeaker or subwoofer can be varied from -10 dB to +10 dB.
In addition to the purely corrective adjustment of the speaker system, you can add more bass into recordings that lack low end.
Good ol' times
Two mechanical VU meters visualize the input levels for the left and right audio channel.
With the VU switch you can optimize the display for different signal levels.
Sources
The Crossover offers both balanced inputs with XLR sockets and standard inputs with gold-plated RCA sockets.
Low & Mid-Hi
On the output side, the power amplifiers or active loudspeakers as well as bass loudspeakers or subwoofers are connected to the Low & Mid-Hi output sockets by means of balanced XLRs. This means that even long cable runs to e.g. mono power amps placed next to the speaker are possible without the risk of interference.
AMP CTL
The AMP CTL sockets can connect up to four power amplifiers with 12 V trigger inputs to switch them on and off together with the crossover. The crossover itself can also be switched on by a preamplifier like the Director Mk2 or Phonitor x.

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
- USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
