POWER
The RB-5000 delivers a continuous power output of 500 watts per channel, minimum RMS, both channels driven into 8 ohms or 4 ohms from 20 to 20,000Hz with no more than 0.009% total harmonic distortion.
ne DC Configuration
Rotel's advanced amplifier configuration assures constantly stable levels of clean-cut, high-fidelity sound from very small to very large outputs. With the DC configuration, capacitors which tend to affect sound quality adversely are removed from the input signal path and the NF loop, and low frequencies are extended down to the DC range leading to a highly responsive bass. In other words, the DC circuitry gives greatly improved damping factor and phase shift at low frequencies resulting in superior rendering of undistorted bass. To develop the effective and reliable DC circuitry, a problem of DC drifts caused by variations in input signals and supply voltage is completely eliminated by advanced electronic design. The high stabilization of differential amplifiers and the linear balance are also achieved
The Perfect Symmetry Design
Essentially, the total circuit configuration of the RB-5000 can be considered as having two identical monorual power amplifiers in one chassis. This is the ultimate design in top class stereo amplifier by
ninating any static and dynamic interferences between the left and right channels. For a further perfection, a completely separate power supply is provided for the relay switching, the peak indicators and the speaker indicators (using a separate—and third—power transformer).
The Class AB Operation
The Class A operation eliminates switching distortion and crosstalk, resulting in more linear and cleaner performance. However, the Class A is highly inefficient considering the fact that very large electrical current must be always fed and much larger heat sinks required for high heat dissipation. In order to effectively utilize the excellent sound quality of the Class A amplification at low power levels and the efficient low-distortion design of the Class B amplification at high power levels, Rotel have combined both operations and developed the Class AB amplification. Hence, at normal listening levels, usually 1 to 3 watts, you can enjoy the superb sound of the Class A amplification, while at any peak and power levels over 3 watts you are assured of same clean passage of music by the Class B amplification. The transition from the Class A to the B is automatic, so you just sit back and listen to a very faithful sound reproduction at incredibly low distortion.
The Amplifier Stages
First Stage (Pre-Driver)—The cascode pure complementary push-pull differential amplifier is used. The dual-transistors installed are especially selected for low noise and excellent electrical and thermal characteristics, providing a proper operation of the DC amplification. By this circuitry, the distortion caused by the variation of input signal impedance is substantially reduced, and the very high S/N of over 110dB is readily achieved.
Second Stage (Pre-Driver) — The cascode symmetrical push-pull differential amplifier is also used in this stage. The complete stability is easily obtained as the result, reducing the thermal variation of the center-point voltage and the DC drifts. In addition, a negligible overall distortion is realized by a strict selection of special low-noise type transistors and other semiconductors.
Output Stage—The Darlington direct-coupled 4-stage linear complete-mirrored parallel push-pull circuitry is used to maintain stable high power level at very low distortion. 4 huge power transistors, each having a perfect matching characteristics and a capability to handle 150 watts, are provided for each channel. This configuration assures the highlinearity operation and eliminates non-linear distortions, as well as warrants ample margin for thermal effect. Since the circuit configuration is completely symmetrical (mirrored), top and bottom and left and right, a very high order of balance is achieved. In effect, this makes the abundant use of NF to obtain low distortion obsolete, as much lower distortion can be achieved—so low, it approaches the measurable limit of instrument—due to extremely outstanding circuit design and well-selected highquality electrical parts.

The Protection
With the various protection circuits to completely protect itself from all possible electrical and thermal damages. To protect the power transistors, an ASO (Area of Safety Operation) detect current limiter circuit will automatically control the current flow and stop any abnormally large surge of current. The output circuit incorporates a overload limiter, which prevents any abnormal overloading. For the speaker protection, a DC detector circuit is used. In order to keep the quadrant heat sink block from overheating (in case the fan system fails), a detector circuit is connected to the thermostat. The latter two detector circuits will activate the protection relay system which shuts down the current flow and lights up either the overload or the protection indicator on the front panel. In addition, to overcome the problems of loud pop-noise and abnormal in-rush current when turning the power switch on, a separate relay and an in-rush current absorber circuit are equipped. Combined with the high quality materials and parts severely selected for realiability and durability, the above protection system offers an incomparable safety operation of the RB-5000.
The Power Supply
Toroidal power transformers not only eliminate such problems as magnetic leakage flux and overheating, but also greatly improve power regulation and transient response. The RB-5000 uses two enormous and high-efficient toroidal power transformers, one for each channel to maintain big power outputs with constant ease. Coupled to each of this transformer are two large cylindrical 22,000µF electrolytic capacitors, (exclusively designed for
the RB-5000 in order to assure a high standard of operation). The third and conventional yet wellconstructed power transformer is used to run the relay switchings (protection relays and speaker relays) and LED's (peak indicators and speaker indicators).
The Cooling System
In order to eliminate the problem of overheating by high power output, the RB-5000 incorporates a quadrant-structured heat sink block and an automatically forced air cooling system. The cooling fan module is entirely made of moulded plastic, except for the specially-designed ball-bearing system. This allows the quietest running operation possible, so you will not be annoyed by a fan noise. The fan system is always activated and its rotational speed is controlled by the thermostat attached to the quadrant heat sink block, which houses the power transistors and is constructed to give efficient heat dissipation.
The Front Panel Controls
There are three pushbutton switches for three pairs of speaker systems with individual LED indicator. The input ON/OFF switch on the center to cut off input instantaneously. The 22-stepped attenuator-type level controls (from –21dB to 0dB calibrated). The 3-position low frequency filter selector. The 3-position meter sensitivity selector and the 3-position power limiter selector. In other words, all conceivable controls needed to run the RB-5000 effectively and smoothly.
Cooling unit
The Rear Panel Connections
There is the facility for hooking up three pairs of speaker systems. The heavy duty speaker terminals are used for safety sake and to take big-diameter shielded speaker wires. Beside the pair of normal RCA-type input jacks (gold-plated for prevention against corrosion to maintain sound quality), there is also a pair of Cannon sockets for professional studio use. For a convenience, four large plastic legs are installed for servicing.
The Cosmetic Appearance
The magnificent appearance of the RB-5000 matches the electronic quality it houses. The extruded aluminum front panel is 5mm thick with another layer of aluminum subpanel surrounding the power meters and peak indicators. The knobs used are all solid extruded aluminum for heavy duty use. The RB-5000 is EIA 19-inch rack mountable, and comes with two big aluminum grab handles. For added convenience, two durable casters are installed on rear of the bottom plate so that the unit can be moved readily by rolling on the surface.
POWER BA
The Indicators
Power Meters – Two big, precision meters give clear visual indication of average power levels in watts and decibels (calibration based on 8-ohm load). The meter sensitivity can be varied by using the 3-position sensitivity selector switch, allowing a very wide visual coverage from 5mW to 1,000W (-50 dB to +3 dB).
Peak Indicators (LED) – 8 LED's per channel will visually indicate the instantaneous peak levels of power output. When used in conjunction with the power meters, they act as a superb tool for checking setting of level controls.
Standby Indicator — This LED lights up when the power switch is turned on, showing that the RB-5000 is on the warm-up stage. It automatically distinguishes when the warm-up time is over. The Overload and Protection Indicators — These LED's light up when the protection system is activated to warn that malfunction has occured. The overload indicator shows malfunction by overheating in the heat sink block, and the protection indicator implies malfunction by speaker wire shorting or abnormal DC flow.

The Volume Control
The RC-5000 purposely uses the continuous variable type volume control instead of a usual stepped type to achieve more linearity and higher S/N ratio. The input side of the flat amplifier is affected by the volume level of the flat amplifier is affected by the volume level of -40 dB to infinity. This unique volume control configuration results in superior characteristic and reduced noise (at the infinity position-minimum level-the residual noise is only 5.6 v/)
contract
The Switchable Phono Characteristic Switches
Failure to give correct load capacitance, resistance and sensitivity to a magnetic cartridge results in poor high frequency response. Three switches are incorporated on the front panel of the RC-5000 for obtain the optimum matching to any particular MM (moving magnet) type cartridge chosen. These permit choice of 6 additional capacitance settings (0, 50, 100, 200, 300, 400 pF), 6 load impedances (15k, 25k, 35k, 50k, 70k, 100k), and continuously variable sensitivity level (from 8 to 2 mV). Note the switches are effective for a turntable connected to the PHONO 1 position.
The Octave Equalizer
Instead of the standard tone control circuit utilizing only bass and treble controls (as well as turnover roll-off switches), the RC-5000 is installed with the octave equalizer. This will give the user more flexibility in improving and expanding original sound components and range, especially useful for room acoustic compensation and high quality tape recording.
The octave equalizer employs a discrete resonant configuration (composed of only transistors, capacitors and resistors instead of commonly used but inferior inductor—coils—system) for its frequency control and vital systems which results in very low distortion and high S/N ratio. The center frequencies are divided into 10, with each band of the particular center frequency adjustable by a slide level control for the ±12 dB range. In essence, the whole audible frequency range is effectively covered for maximum adjustable flexibility. A 5-stage direct-coupled circuit with a FET first stage DC-connection assures wide dynamic range and incredibly negligible noise.
The Low and High Filters
These are -12 dB/octave active filters composed of a 2-stage Darlington direct-coupled onfiguration with a FET input stage and bi-polar transistors. The two-position switch allows the low filter to be selectable for 15 Hz or 4 Hz setting (both settings are at subsonic frequencies, useful for cutting out unwanted noise effects at very low frequency range). The two selectable positions are also available for the high filter, with the 24 kHz setting useful to avoid unwanted components from the very high frequency range affecting the audible range negatively.
The Separate Recording Selector Control
The REC OUT control located on the front panel of the RC-5000 makes it possible to choose a signal desired for recording by tape recorder regardless of the input source one may be listening to. For instance, this makes possible the recording from turntable while listening to FM broadcast. The full tape dubbing between two tape recorders (or between one recorder and two other recorders) is also controlled by the REC OUT control, regardless of what is being played through the control amplifier.
he Microphone Amplifier
2 high quality IC's and super-low-noise FET are used on each channel of this amplifier to ensure large overload characteristic and improve S/N ratio. The high quality concentric level controls are incorporated for the smooth mic mixing, along with the 2-position mic impedance selector and the 3-position mode selector. Hence, a highfidelity recording is possible with this professionalcaliber mic amplifier.
Microphone amp circuit diagram
The Power Supply
The highly stable dual power supply circuit using two specially designed power transformers (for independent supply to the left and the right, channels) assures excellent regulation and clean
response. Moreover, a third separate power transformer is built-in to supply power independently to the headphone amplifier and the relay system.
The Cannon Type Input/Output Terminals
On the rear panel of the RC-5000, one pair each of the Cannon input and output sockets are equipped for the professional usage such as by broadcasting studio. The input has 600-ohm balanced impedance with one buffer amplifier/ one-stage differential amplifier/3-stage directcoupled circuit to maintain interference-free high quality characteristic. The output is also the 600-ohm balanced impedance type with 3-stage
direct-coupled, 1-stage differential amplifier, Class A single-end push-pull circuit to prevent crossover and switching distortions affect high performance characteristic.
The Facilities
The RC-5000 is endowed with the complete facilities, such as the connection for up to three tape recorders and the full dubbing feasibility among these tape decks; the connection for up to three turntables (one exclusively for the MC cartridge use) with the front panel switchable loading selector switches to perfectly match characteristics of particular MM type cartridge used for PHONO 1; the connection for two auxilliary equipments, with one switchable to become the Cannon input/output terminals to accept professional-use component; the connection for the stereo mics with own mixing level control, impedance selector and mode selector; the connection for two stereo headphone sets with 2-position impedance selector switch for PHONES B; the octave equalizer section with 10 slide level controls, as well as the tone cut switch to deactivate the equalizer together with or without the low and high filters; and the convenient switches such as 2-position muting switch. 2-position loudness switch, 5-position dual mode switches. In addition, all RCA type jacks on the rear panel are gold-plated for prevention against corrosion to adversely affect sound quality.
The Cosmetic Appearance
The grand appearance of the RC-5000 not only matches the quality electronics it houses, but also the RB-5000 its perfect partner. The extruded aluminum panel is 5 mm thick with two subpanels overlaid (one displaying octave equalizer section and the other the main controls. The knobs used are all solid extruded aluminum, except the octave equalizer slide control knobs which are heavy-duty plastic molds.
