- Page 4 Our design philosophies have been influenced by both the professional and home audio markets. Traditionally the professional market has been driven by reliability with sound quality as second. The home market was the reverse. Today however both reliability and sound quality carry equal weight in both sectors. Cosmetics for obvious reasons are important in any sector.

Page 5: Installation Instructions
Installation Instructions Location: Choose a suitable location in the vehicle which will allow sufficient airflow over the amplifier. The preferred mounting direction is with the heatsink fins in a vertical direction. However we do recognize that this is not always possible. DO NOT mount the amplifier upside down as this reduces the ability of the heatsink to dissipate heat effectively. -
Page 6: Connecting The Amplifier
Connecting the Amplifier Once the amplifier has been correctly mounted the electrical connections can now be made. The first step is to connect the loudspeakers. Using the appropriate size of wire (we recommend a min of #14) connect the speakers as shown in later diagrams, depending on which amplifier(s) are being installed. - Page 7 Farad capacitor = 0.5CV.V = 0.5x1x12x12= 72 Joules. Let us assume a medium size amplifier such as Draconia. Let us assume that we are playing it such that all four channels(into 4 ohms each) are just clipping on the loudest musical peaks. This means that we are delivering 300 watts on peaks.
- Page 8 Setting the controls on amplifiers evel control - This control is the most misunderstood control on any amplifier. It’s sole purpose in life is to level match the head unit’s output voltage to the gain structure of the amplifier so that the user can use the head unit’s volume control in the “best physiological position”.
- Page 9 amping Factor - This amplifier specification has been blown out of all proportion. What it means is the ability of the amplifier to resist a change in it’s output voltage. The formula is DF= Speaker Z / Amplifier output Z (where Z is impedance). So many manufacturers have claimed ridiculous, and often false damping factors.
- Page 10 ridging two channels of an amplifier is not a magical thing. Most are mystified by the power figures quoted under the “bridge” column. It is actually very simple. When two channels are driving a common load, one channel is out of phase with the other by 180 degrees.
- Page 11 o a 100w/ch amplifier running into 4 ohms must develop 20 volts across the speaker terminal. This requires a net (under load) rail voltage of about +/- 33 volts. Now for it to have 3dB of headroom it must be capable of delivering 28.28 volts across the speaker terminal.

- Page 14 Megalith For those of you acquainted with ancient history we know that the Egyptians amongst others built massive temples and monoliths. These monoliths were single massive stone structures, wider at the base and tapering at the top and exuded a feeling of power and mass.
- Page 15 Our power supplies use massive amounts of capacitance on the 12 volt side and this capacitance is spread over 19 capacitors in parallel. A total of 41,800mfd is used. Fourteen (14) high current low Rds on Mosfets are used as the main switching elements. Each is rated at 110 amps but we derate them to 50 amps for safety and each has an “on”...
- Page 16 The pre-amplifier has 5 inputs, four of them allow the front and rear outputs from a head unit to mixed to mono. The fifth input does double duty. When the MODE switch is in the “normal” position the fifth input (mono) accepts a mono input, such as the mono sub outs from some head units.

Between 18 and 27 inches (455 to 685mm) in length and made from hardened steel attached to a wooden handle it was a deadly weapon in the hands of a soldier.

- Page 24 SELECTOR switch on channels 1 and 2 (see above note). So Draconia can then be run with all channels in low pass and all running off inputs 3 and 4. The channels may be bridged or run as stereo pairs.
- Page 25 Thus it is possible to have the front and rear outputs from a head run into Draconia and then all 4 channels are run as low pass. Thus Draconia can be run as a sub amplifier and again the channels can be run individually or in bridge mode. Sounds like quite a mouthful but it is actually simple.
- Page 26 4) If the LP crossover on the sub amp is preferred over that of Draconia then simply turn the LP crossover to 3.5KHz and this removes the LP crossover of Draconia from the pass band.
