GOLD PLATED TERMINALS:
All the terminals on the amplifier are solid brass and platinum 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 lug and spade connectors for optimum signal transfer.
POWER AND PROTECTION CIRCUITRY:
RX Phenom 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:
RX Phenom 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 18dB 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 18dB
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
RX Phenom 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 RX Phenom 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.) Rockville uses only true audio transistors in the audio
section of these amplifiers. These transistors were designed and engineered to produce
music. That’s why Rockville amplifiers clearly sound better. They are cleaner with lower
distortion, higher current capable and more reliable. We challenge you to test listen a
Rockville amplifier and hear the difference yourself.
