Installation manual

Zed Audio is proud to introduce our third line of innovative mobile amplifiers. The new
products were carefully selected to fill the need of the car audio enthusiasts.
The first is MINOTAUR an all new single channel (mono block) rated at 600w into 4 ohm and
1000w into 2 ohm. This is not your normal “run of the mill” mono block since this is actually a
full range amplifier with some unique features.
DRACONIA is the smaller of the new four channel offerings at 125w x 4 at 4 ohms and
DREADNOUGHT is the “Bad Boy”rated at 250w x 4 at 4 ohms. These amplifiers are suitable
for use in almost any system, small or large.
LEVIATHAN our six channel amplifier has been improved and some of the crossover
frequency selections have been updated.
RA the last of the new products is a remote control/pre amplifier whose features are
dedicated for sub-woofer duty.
Some facts about our amplifiers:
We use only high current large pack TO-247 MOSFETs in the power supplies. These are
superior to the smaller TO-220 packages in their ability to dissipate heat.
The power supplies are fully regulated and so the amplifiers are independent of battery
voltage (>12v).
Low ESR 105 deg C capacitors are used in the power supplies. Additional high frequency
bypass is done with ceramic capacitors (the best choice by far for this application).
High speed (35nsec) rectifier diodes are utilized for the secondary supplies and all low
voltage supplies use Schottky diodes which have zero reverse recovery time.
The main high current power supplies which feed the power amplifiers are choke type for
superior filtering and noise rejection and again low ESR 105 deg C capacitors are used.
All amplifiers feature a two stage power supply for increased efficiency.
New super high speed low noise IC chips are used.
The class D amplifiers utilize the latest generation of low gate charge, high current
MOSFETs.
MINOTAUR is an industry first with a
The pre-amplifiers in all our amplifiers run off independent regulated supplies and drive the
power amplifiers in a full balanced differential mode.
This method of internal connection eliminates ground loops which cause alternator whine.
It also eliminates the need for balanced inputs of which we see many manufacturers using
RCA connectors which were NEVER designed for balanced connection.
Clipping LEDs are featured on all amplifiers.
MINOTAUR has 4 LEDs each spaced at 3dB intervals. (0dB, -3dB, -6dB and -9dB)
All amplifiers which have equalizers use constant Q types for a more precise result.
RCA sockets are solid gold plated machined brass with teflon inserts.
The power connectors accept wire with a diameter of 7mm (0.275”).
Low noise 1% metal film resistors are used in all gain and frequency dependent circuits.
All our amplifiers feature the usual plethora of protection circuits, such as DC, thermal and
short circuit. The short circuit is auto resetting and requires no input from the user.
The ZED logo doubles as a power and a protection indicator, flashing in protect mode and
solid under normal operating conditions.
48dB/octave analog High Pass crossover.
