CAUTION

POWER LINES

Any outdoor antenna must be located away from all power lines.

OUTDOOR ANTENNA GROUNDING

If an outside antenna is connected to your tuner or tunerpreamplifier, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA No. 70-1984, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes and requirements for the grounding electrode.

a.Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2) aluminium, No. 17 AWG (1.0mm2) copper-clad steel or bronze wire, or larger, as a ground wire.

b.Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4-6 feet (1.22 - 1.83 m) apart.

c.Mount antenna discharge unit as close as possible to where leadin enters house.

d.Use jumper wire not smaller than No.6 AWG (13.3mm2) copper, or the equivalent, when a separate antenna-grounding electrode is used. see NEC Section 810-21 (j).

EXAMPLE OF ANTENNA GROUNDING AS PER NATIONAL ELECTRICAL CODE INSTRUCTIONS CONTAINED IN ARTICLE 810 - RADIO AND TELEVISION EQUIPMENT.

NOTE TO CATV SYSTEM INSTALLER: This reminder is provided to call the CATV system installers attention to Article 820-40 of the National Electrical Code that provides guidelines for proper grounding and, in particular, specifies that the ground cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.

KRK Systems’ Design Philosophies

Thank you for purchasing the KRK10s active studio subwoofer. We are the most dedicated monitor company in the world and we are thrilled you have joined our ever growing family of loyal customers.

Our Focus is Your Mix

At KRK, our focus has always been to make the most accurate studio monitors available at any price.

We don’t offer PA gear, mixers or motorcycles – just the tools you need to deliver a great mix. From the legendary Exposé Series, to VXT to the new RoKit Generation 2 (“G2”) series

– we know recording monitors.

We do not add sonic characteristics like some other manufacturers that make their monitors appear to provide more SPL or add low frequencies that demo well in the store.

When you use a KRK monitor,you can be confident that your mixes will translate well to the wide variety of playback conditions that can occur in the real world. We want your audio mixes to sound good everywhere – not just in your studio!

Port Design

Our ports are designed to greatly reduce air flow turbulence for high performance audio reproduction. The result? Clear, accurate and well designed low frequency extension.

Even More Accurate than Before

We tweaked our speaker voicing to provide even more accurate frequency response for amazing audio reproduction using our custom made KRK drivers. What you hear is what you get, where ever your music is being played. Our drivers are all custom-designed by our world-class studio monitor engineering team.

Imitation but not Perfection – A Statement to our Competition

If the sincerest form of flattery is imitation, we must own that aspect of the recording monitor world. From using Kevlar in driver designs to copying our radiused edge approach, the competition knows a good thing when they hear it. However, chasing our past won’t deliver a product that comes close to the sound of a KRK monitor. See ya later competition!

Enough About Us – Let’s Get Going!

So enough about why we do the things we do. Let’s read on about the features of your new KRK subwoofer so you can start enjoying your new subwoofer now!
