Elcome to the world of zed audio amplifiers. Designed for mobile use, these amplifiers are the cumulation of more than 25 years of cutting edge design. This w is not to say that these new products took 25 years to design, but rather that they have the “experience” of 25 years of manufacturing and de...

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 bot...

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 amplifi...

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 amplifi...

Zed does not recommend the use of power distribution blocks for the purpose of distributing the +12volt voltage to several amplifiers. The reason is that the vehicle’s battery is the lowest ac impedance point in the power grid of the vehicle. We want each amplifier to draw it’s current from this low...

Setting the controls on amplifiers evel control - this control is the most misunderstood control on any amplifier. It’s sole l 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 ...

Amping factor - this amplifier specification has been blown out of all proportion. D 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 o...

Ridging two channels of an amplifier is not a magical thing. Most are mystified by the b 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. So when one channel swings posi...

O a 100w/ch amplifier running into 4 ohms must develop 20 volts across the speaker s 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. This requires a rail voltag...

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. We wanted our new mono bloc...

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 t...

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. The sensiti...

Gladius and the deuce hat a combination these two are. Gladius,(which is latin for sword) was the famous w roman short sword used by the romans. 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...

Re-amplification is such an important part of any mobile amplifier. We incorporate a p pair of high and low pass crossovers both with 24db/octave slopes. The frequency range covered is sufficient to allow these crossovers to be used in tri-amplified systems. The amplifiers may of course be run full ...

Draconia reece, the ancient land where the modern day olympics was born and from where g alexander the great ruled a vast empire for 33 years. 300 years before alexander was born, a guy named draco, instituted a code of laws so harsh that they became known as draconian laws. Zed audio also has a law...

The bandpass crossover frequencies are variable over a wide range and will accommodate all midrange drivers. The last position is mix and in this mode all of the four inputs are mixed into a single mono signal and then run through the low pass crossover. Thus it is possible to have the front and rea...
