VRM12 – 7• Using the Pin 2+,2- Speakon connections to connect the second power amplifierchannel to a subwoofer.• Using the Pin 2+,2- Speakon connections to connect the second power amplifierchannel to a second VRM12. You will need a cross-wired cable which has Pins 2 atone end connected to Pins 1 at the other.Loudspeaker Cables• Use loudspeaker cables with a minimum conductor size for the length you need,as listed in these tables. This will minimizepower losses to less than 0.5 dB. Thecable lengths listed are “up to” lengths.For in-between lengths, use the next largerconductor gauge. Using larger than therecommended conductor size is alwayspermissible. Using smaller than recommendedconductor size will result in higher powerlosses.• The recommended conductor gauges arelisted for AWG (American Wire Gauge) andMetric WG (Metric Wire Gauge). Note thatsmaller AWG numbers = larger conductorsand smaller Metric WG numbers = smallerconductors. The Metric WG is equal to tentimes the nominal conductor diameter inmillimeters.• For cable lengths over 200 feet / 60 m at 8 ohms, and over 100 feet / 30 m at 4 ohms,the conductor sizes needed for less than 0.5 dB power losses are rarely practicalfor physical and cost reasons. As a practical compromise for these situations therecommended conductor gauge is 10 AWG or 25 metric.Minimum AWG 4 ohm 8 ohm18 10 ft 25 ft16 25 5014 25 7512 50 12510 100 200Min Metric WG 4 ohm 8 ohm12 3 m 8 m14 8 1516 8 2520 15 4025 30 60xoverVRM12 enclosurePinSpeakon SpeakonPin1+1-2+2-1+++ +1-2+2-xoverVRM12 enclosurePinSpeakon SpeakonPin1+1-2+2-1+++ +1-2+2-Amp A+B+xoverVRM12 enclosurePinSpeakon SpeakonPin1+1-2+2-1+++ +1-2+2-SubAmp A+B+4-conductor cable4-conductor cablecross-wired cableLead Guitar(for example)Bass Guitar(for example)+
