Nearfield HF coverage limit Note that the W8VDQ s differential dispersion does not allow vertical arraying or stacking The Martin Audio W8LM line array system provides optimal vertical coupling for vertical array applications Horizontal arraying up to 60 100deg between W8VDQs is possible 5 Amplification amp Control Choosing a power amplifier Martin Audio loudspeakers are capable of recreating musical dynamics accurately and with incredible impact if powered correctly Martin Audio loudspeaker power ratings are quoted for AES power a long term average power rating and Peak power a short term burst capability Moving coil loudspeakers can be run up to their AES power rating continuously and up to the higher Peak power rating for transient musical peaks Choose an amplifier with a power capability approaching 3200W into Gohms This means choosing a Martin Audio MA9 6 or MA12K power amplifier For spectral balance set your amplifiers to the same voltage gain throughout the system A common industry standard voltage gain is 32dB x40 All Martin Audio limiters are set for this level If you use Crown amplifiers without a 32dB setting set them to their 26dB x20 standard and increase the recommended limiter thresholds by 6dB making sure you double check the amplifier gain setting before running the system at high level Always check the amplifier gain settings these are usually on the rear panel Avoid using sens
