Thank you for purchasing this KV2 Audio, SL series system, consisting of the SL3000 stereo controller/ampli-
fier unit, two SL412 speakers and optional variants of subwoofers.
The SL412 and SL2.15 speakers incorporate an eye catching, slim, stylish cabinet design. Designed to inte-
grate either externally through simple wall mounting, suspension, ground stacking, or internally into walls
and surfaces. These units can be designed and supplied with custom colors, grill templates and logos, of-
fering a flexible and true designer integration product. Using KV2 Super Live Audio technology, the SL412
loudspeaker utilizes 4 x 12”low mid-range components and the proven and highly respected horn assembly
from the VHD1.0 with a single 8” mid-range and 3” large format NPVD compression driver. This mid-high
horn has an extremely coherent-wide horizontal dispersion of over 110 degrees whilst the purpose desig-
ned 4 x 12” configuration dramatically reduces the most common problem of immediate reflections within
the 300÷800Hz range usually associated with wide dispersion loudspeakers. The end result is a full and wide
sound propagation exactly where it is required. Whilst the SL412 can be utilized with any of KV2’s wide range
of subwoofer systems depending on the actual application, the accompanying SL2.15 utilizes the same slim
line design to allow for an aesthetically pleasing and acoustically punchy system that can virtually disappear
against a wall. The SL2.15 incorporates 2 x 15” speakers in a specially designed shallow cabinet to output
maximum bass response.
This manual contains important information on operating the SL system correctly and safely. Please take
some time and read this manual to familiarize yourself with the advanced features of this system.
The SL3000 Amplifier is a three-way, active control and amplification systems, specifically designed for the
KV2 Audio SL series loudspeaker systems. It houses all signal processing and amplification as well as provi-
ding control for external subwoofer cabinets configurations, and to operate additional subwoofer cabinets
if needed. External subwoofers are powered by the external subwoofer amplifier (VHD3200).
In most cases it would be advisable to use a KV2 Audio Line driver (LD4) in addition at the mixer end to en-
sure that the line to the amplifier is driven correctly and the signal integrity maintained.
Although this system is simple to operate, improper use can be dangerous. This is a very high-powered de-
vice that can put out high voltages and sizeable currents. Always use safe operating techniques with the SL
series system.
FOR YOUR SAFETY, READ THE IMPORTANT PRECAUTIONS SECTION AS WELL AS THE INPUT, OUTPUT
AND POWER CONNECTION SECTIONS OF THIS MANUAL.
