OWNER’S MANUAL

Introduction

We thank you for purchasing our amplifiers. Your decision to be part of something different
is what we strive for. Our products reflects who we are, going to the extent to deliver you
our finest comes natural.
Our amplifiers are engineered to accomondate a variety of applications.
Whether it is SPL or SQ, the sound provided will be clean & dynamic.
We refer to it as SQL audiophile products, based on optimizing every aspect of the amplifier
to have the highest possible efficiency, while minimizing distortion, causing less stress on the
audio reproduction and increasing the Sound Quality & output performance.

To obtain the full potential of the amplifier & to minimize failure, it is strongly recommended & necessary to upgrade the stock electrical system.
Ensure the system is in accordance with the full performance of the amplifier. It is therefore essential to read through the whole manual.

Better Bass

Better Bass is our philosophy of adding something extra.
Keep in mind that continious exposure to SPL above 100 dB can seriously
damage your hearing. Today’s high power auto sound systems can easily
produce SPL over 140 dB. Enjoy your music with sense.

Description of Specifications

Stable impedance load of the Zero.7s is 1 Ohm.

Operation below minimum impedance will stress the amplifier & void the warranty.
Excessive heat will also appear at a faster rate and the and the amplifier will go into thermal protection.

Protection can also be caused by the following

* Speaker overload
* Short circuit
* Input Voltage - RCA & Power Supply

The PCB is a HI-EF Class D design. THE HI-EF circuit optimizes efficiency & improves performance even at low voltages.

Operational voltage: 10 V ~ 15 V.
Operational voltage will also be affected by the load of the amplifier.

*In order to get the full power output of the amplifier, it is crucial that your electical system is correctly (over)dimensioned. Failure to upgrading, will constrain the power

output & lower the effeciency which can cause damage to the amplifier & void the warranty, this also includes loads below min. of what is written in the manual. Read
the manual thoroughly before installing!

** The 0.5 Ohm rating of the Zero.7s requires voltage is kept at or above 14.4 V & the signal is ran up to the point of soft-clipping. An additional 0.5 Ohm warranty is

obtainalbe through your authorized dealer given the conditions are met.
