The Yamaha R1000 is a high-performance digital reverberation unit designed for a wide range of instruments, stage equipment, and mixers. It incorporates advanced digital signal processing to provide versatile and affordable reverb effects.

Function Description

The R1000's primary function is to add reverberation to audio signals, simulating the natural echo and decay of sound in various acoustic spaces. It achieves this through digital processing, offering a clean and stable alternative to traditional spring-type reverb units, which can be susceptible to physical vibrations.

Reverb Modes: The unit features a MODE SELECTOR that allows users to choose from four distinct reverb time settings: 1.5, 1.6, 2.3, and 2.4 seconds. These progressively longer delay times enable the creation of more realistic effects, suitable for different environments such as large auditoriums or concert halls. The selected mode is indicated by a corresponding illuminated lamp on the front panel.

Parametric Equalizer: A key feature of the R1000 is its three-band parametric equalizer, which provides extensive control over the reverb sound. This equalizer allows for continuous adjustment of low, mid, and high frequencies, enabling users to tailor the reverb's tonal characteristics precisely.

LOW: Adjustable from 50Hz to 700Hz.
MID: Adjustable from 350Hz to 5kHz.
HIGH: Adjustable from 2kHz to 20kHz. Each band offers a maximum of 15dB peak or dip adjustment. The equalizer can be activated or deactivated using the EQUALIZER SWITCH; when off, a "flat" signal is reproduced, which can improve the signal-to-noise ratio compared to setting all equalizer controls to "0."

Mixing Control: The MIXING CONTROL knob allows for continuous adjustment of the balance between the direct (unprocessed) signal and the reverberated signal. Turning the knob towards "DIRECT" emphasizes the original sound source, while turning it towards "REVERB" increases the prominence of the reverb effect. At the extreme "DIRECT" position, only direct signals are output, and at the extreme "REVERB" position, only reverb sounds are produced.

Input and Output Level Controls:

INPUT LEVEL CONTROL: This knob adjusts the level of the incoming audio signals. For optimal signal-to-noise ratio and dynamic range, it is recommended to set the input level as high as possible without causing the "+10dB" lamp on the INPUT LEVEL METER to light, indicating clipping. When using the equalizer to boost frequencies, the input level should be set lower to provide sufficient headroom for the equalizer circuit.
OUTPUT LEVEL CONTROL: This knob adjusts the overall output level of the unit. It affects the volume of the reverb signals but does not influence the output level of bypass signals.

Bypass Functionality: The R1000 includes a BYPASS SWITCH on the front panel and a FOOT SWITCH TERMINAL for remote operation. When bypass is activated, the input signals completely bypass the reverb and equalizer stages, being routed directly to the output terminals. This allows for quick switching between processed and unprocessed sound, particularly useful during live performances. The foot switch terminal overrides the front panel bypass switch.

Insert In/Out: The INSERT IN/OUT terminals provide flexibility for integrating external effects processors. By plugging into the INSERT IN jack, the internal circuitry is shorted, allowing external signals to be applied to the input. This is useful for incorporating compressors, faders, or other effect units into the signal chain.

Usage Features

Ease of Use: The R1000 is designed with simple controls, making it easy to operate while still offering flexible sound shaping capabilities.

Input Level Monitoring: A 4-segment LED INPUT LEVEL METER provides a clear visual indication of input signal levels. This helps users set appropriate input levels to prevent clipping and maintain a high signal-to-noise ratio. The meter displays the level of signals transiting through the input level control and insert in/out terminals, or specifically the level of INSERT IN signals when those terminals are used.

Connectivity:

Input Terminal: An unbalanced phone jack with 50 Ohms input impedance, suitable for connection to keyboards or mixers. For electric guitars or low-level, high-impedance units, a preamplifier or effecter may be required.
Output Terminal: An unbalanced phone jack with 100 Ohms output impedance, connecting to a mixer or power amplifier. Signals can pass directly from input to output even when the unit's power is off.
Level Selector Switch: This switch adjusts both input and output stages to either +4dB or -20dB, ensuring compatibility with the connected equipment and preventing level discrepancies.

Delay Machine Integration: The R1000 can be used effectively with a delay machine to create pre-delay effects. Pre-delay simulates the natural time gap before reverberation occurs in a real acoustic space, enhancing the realism and pronounced effect of the reverb. The delay time can be set from several to 10 milliseconds.

Without Mixer: The balance of pre-delay and direct signals is adjusted via the R1000's mixing control.
With Mixer: Using a mixer's pan-pot, direct and pre-delay signals can be separated into left and right channels, creating enhanced sonic dispersion.

Rack Mountable: The unit is designed for mounting in standard 19-inch audio racks, making it convenient for studio or live sound setups.

Maintenance Features

Durability and Stability: The R1000's digital design eliminates the physical vibration issues common with spring-type reverb units, ensuring highly stable operation in virtually all situations.

Power Supply:

Voltage Selector: For general models, a VOLTAGE SELECTOR switch on the rear panel allows users to set the unit to their local AC mains voltage (110-130V or 220-240V AC, 50/60Hz). It is crucial to set this correctly before plugging in the unit to prevent damage. U.S. and Canadian models typically do not include this selector.
Power Switch: A simple ON/OFF POWER SWITCH controls the unit's power. An indicator lamp above the MODE selector illuminates when power is on and extinguishes when off.

Care and Handling:

Placement: The R1000 should be located away from direct sunlight, excessive dust, heat, cold, moisture, and areas subject to vibration to ensure optimal performance and longevity.
Disconnection: When moving the unit, always disconnect the power supply cord and all connecting cords to prevent breakage or short circuits.
Cleaning: Do not use chemical solvents (such as alcohol or benzene) to clean the unit. Instead, wipe it with a clean, completely dry cloth to remove dirt.
Manual Retention: Keep the operating manual in a safe place for future reference and consult it frequently to become fully familiar with the R1000's operation.
