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.
