The DX1 may be user-programmed to many more touring and fixed installation
configurations based on its 2 input + sum, 6 output matrix. This operation is best
completed by an audio technician who is familiar with DSP-based pro-audio.

A1.6Power amplifier recommendations
Wavefront Series loudspeaker systems have been designed and manufactured for very
high performance and arrayability. The systems are very easy to use - particularly if
power amplifier racks and controller settings are standardised within a system.
Power capability
The Wavefront W8 will provide full performance when driven by professional power
amplifiers capable of delivering undistorted output power into a range of loads as
follows:
W8
250-300W(AES) into 8 ohms,
500-600W(AES) into 4 ohms
and
1,000-1,200W(AES) into 2 ohms.
Please note:
Amplifiers with inadequate headroom before clipping may age high frequency
components due to excessive signal density.
Amplifiers with excessive output may damage voice-coils or age driver suspensions
due to excessive heat dissipation and excursion.
A note about power amplifier output specifications
Most power amplifier manufacturers keep their costs down by using unregulated
supply rails which sag under load. To allow for this sag, manufacturers set their rails
high so that they still meet their quoted output into specified loads. These high rail
voltages allow such power amplifiers to provide outputs 1.5 - 2 times their quoted
power for short-term bursts. Martin Audio products will withstand this potential
doubling of instantaneous power - with suitably set controller limiters - but further,
long-term increases caused by oversized amplifiers should be avoided.
Martin Audio MA Series Power Amplifiers
Martin Audio MA Series amplifiers have regulated rails so it is quite permissible to
use slightly overpowered models - with suitably set controller limiters - without
risking uncontrolled power bursts. The MA series power amplifiers’ regulated power
