    For those of you who have used our previous products, much of the information in this manual will be familiar. We have added some new interesting titbits. Over the past four years since the first zed amplifiers were introduced, several events have occurred which have moved us into a new dimension of...

    So with these facts established our class a or class b amplifiers channel power supply energy to the speaker but waste a lot of energy performing this feat. Class b amplifiers can be made more efficient by using some smart power supply technology. The “enemy” of the class b amplifier is the value of...

    Output level all the time, in fact very rarely. So referring back to the fact that the average level is about 10-15% of the maximum or peak power of the amplifier, the efficiency is substantially lower than the 90+%. Typically with a class d amplifier this figure is around 75-85% which is an order o...

    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...

    Semiconductors have more tolerance in their specifications than any capacitor or resistor. A well known fact is that different types of capacitors work better at certain jobs than others. Example, disc ceramic capacitors are better in high frequency compensation circuits than film types. Film types ...

    Z ed 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 lo...

    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...

    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. Mounting the amplifier(s...

    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...

    This, the first of our new full range high quality class d amplifiers has been in development for the past 15 months. The switch to class d was not taken lightly and the target of these new amplifiers was quite simple. Perform as well as our “traditional” class a/ b amplifiers. This target was achie...

    The pwm amplifier utilizes a high frequency carrier which is modulated by the incoming audio signal. The resultant series of variable width pulse trains are switched by the main high current switching amplifier. This section uses ultra high speed precision integrated circuits to precisely control th...

    Converting to run as a subwoofer amplifier is simple. Push in the switch from “2ch lp” to “mono lp. Has some added features. The rca sockets “3” and “4” are now another pair of inputs and so all four inputs can accept signals from the head unit’s front and rear outputs. This allows for constant subw...

    We are absolutely 100% against these low impedance loads . There is no reason to run a “daily driver” or sq system into these loads. The aim is quality after all and not sound pressure. The ego trip of boasting that you have “x mega watts” in the car is just that, an ego trip and serves no other pur...

    Feed the test signal into both inputs. Using an ac voltmeter connect it to one channel of the amplifier and note the reading. Set the balance control to centre. Then connect the voltmeter to the other channel. Hint keep one lead of the meter to either ch1 - or ch 2 + speaker terminals as these are c...
