GOLD PLATED TERMINALS:

All the terminals on the amplifier are solid brass and gold plated for high conductivity and 
minimum impedance loss. The power and ground terminals are extra large and capable of 
accepting 4-8 gauge wire. The speaker terminals can accept 14-16 gauge wire. When wiring 
the amplifier, be sure to strip just enough wire that fits into the terminal so that bare wires 
do not touch each other, or the amplifier chassis and cause a short circuit. We recommend 
using Cadence brand lug and spade connectors for optimum signal transfer.  

POWER AND PROTECTION CIRCUITRY:

Flash  Series  amplifiers  feature  our  unique  IC  controlled  protection  circuitry.  This 
sophisticated circuit constantly monitors the heat sink internal temperature and various 
voltages, adjusting the amp automatically and protecting it from dangerous conditions. 
The 2 LED’s located on the side of the amplifier provide indication of the amplifier status, 
the Power LED will light when the amplifier is receiving proper power, ground and remote 
voltages  and  the  IC  monitoring  sequence  indicates  the  amp  is  functional.  In  case  the 
amplifier  encounters  a  diagnostic  condition  as  listed  below,  the  second  LED  will  light 
indicating a Diagnostic condition. When a diagnostic condition is sensed the amplifier will 
then turn into a self preservation mode and if the cause of the diagnostic condition is not 
corrected will eventually shut down. There are certain critical diagnostic conditions which 
will turn the amplifier off immediately. 

1. Speaker short circuit. 
2. Input Overload. 
3. Thermal overload. 
4. Reverse Polarity. 

To reset the amplifier, you must first diagnose what caused the problem, correct the fault and restart 
the system. See the Trouble Shooting page for further details.

MUTE CIRCUIT:

The Flash Series amplifiers feature an anti-thump, mute and delay circuit. This eliminates 
irritating speaker damaging turn-on and turn-off transients normally experienced with less 
expensive amplifiers.

BASS DRIVE EQUALIZATION CIRCUITRY:

A narrow “Q” shelving equalization circuit is included in the amplifiers. The equalization 
system  is  preset  at  45Hz. The  boost  control  allows  you  to  add  up  to  12dB  of  Bass  Drive 
effect. Utilize the Bass Drive to tailor your bass response to your systems needs. Please keep 
in mind that by adding Bass Drive you are adding stress on your speakers. Make sure your 
speakers can handle the extra power output! It would be foolish to add 12dB of gain to low 
excursion 8” and 10” Sub woofers or mid ranges and tweeters. It’s a sure way to blow your 
speakers. The Bass Drive was designed for High Power sub woofers.

“ADR”: - ACTIVE DYNAMIC REGULATION

Cadence  Flash  Series  amplifiers  feature  our  proprietary  ADR,  Active  Dynamic  Regulated 
power  supplies.  100%  HexFET  devices  are  utilized  in  the  power  supply  for  high  speed 
(100KHz)  switching  frequencies. The  power  supplies  are  capable  of  supplying  the  main 
amplifier with a considerable amount of reserve voltage for peak “high demand” situations. 
The ADR circuit provides full bandwidth power for authoritative bass response, high current 
output into low impedance loads and increased headroom. The ADR is supplied with power 
via a high speed, high temperature capacitance bank and 100% pure copper rails on the 
PCB enabling fast transient response to musical demands.

SUPER CLASS AB AUDIO STAGE PERFORMANCE

The  audio  output  section  of  the  Flash  Series  amplifiers  feature  Japanese  studio  grade, 
high  current  Bi-Polar  audio  transistors.  Unlike  other  manufacturers  who  use  a  host  of 
different type of transistors, not originally designed for audio output, i.e.: power supply 
transistors, motor control transistors to produce the audio signal, (You can only imagine 
what  they  sound  like.)  Cadence  uses  only  true  audio  transistors  in  the  audio  section  of 
these amplifiers. These transistors were designed and engineered to produce music. That’s 
why Cadence amplifiers clearly sound better. They are cleaner with lower distortion, higher 
current capable and more reliable. We challenge you to test listen a Cadence amplifier and 
hear the difference yourself.
