OPERATION MANUAL

Introduction

Thank you for selecting the ZOOM RFX-300 (hereafter simply called the "RFX-300"). The RFX-300 is a sophisticated multi-effect processor with the following features and functions.

- Ideal for use with a multi-track recorder

A total of 22 high-quality preset effects using a sampling frequency of 44.1kHz and 18-bit A/D and D/A converters are built in. This includes reverb effects such as Hall, Room, Plate, and Ambience, delay/modulation type effects as well as combination effects, mixdown effects for changing the overall mood of a song. Any effect can be called up quickly and without fuss. The unit is designed to be especially useful for recording and mixdown on a multi-track recorder.

- Easy operation

The main parameters of preset effects can be adjusted directly with convenient knobs on the top panel. This allows quick fine-tuning for optimum sound.

- Integrated tap input function

Tap input lets you set time-based parameters simply by tapping a key in the desired interval. This makes it a snap to match delay time or modulation rate to the tempo of a song.

- Versatile input/output configuration

The inputs and outputs of the RFX-300 accommodate both standard phone plugs and RCA type phono plugs. Electronic instruments, multi-track recorders, various audio components and a wide range of other equipment can be connected without hassle. The phone jack input is equipped with a gain switch, allowing connection of microphones as well. You can use the RFX-300 as a portable vocal effect device or as a microphone preamp for recording.

- Dual power supply design

The dual power supply principle allows the unit to be powered from an AC adapter or six IEC R6 (size AA) batteries. This is convenient for example when using the unit on stage.

• Connect the AC adapter only to an AC outlet that supplies the rated voltage required by the adapter.
• When disconnecting the AC adapter from the AC outlet, always grasp the adapter itself and do not pull at the cable.
• When not using the unit for an extended period, disconnect the AC adapter from the AC outlet.

[Battery Powered Operation]

• Use six IEC R6 (size AA) 1.5V batteries (alkaline).
• The RFX-300 cannot be used for recharging.
  Pay close attention to the labelling of the battery to make sure you choose the correct type.
• When not using the unit for an extended period, remove the batteries from the unit.
• If battery leakage has occurred, wipe the battery compartment and the battery terminals carefully to remove all remnants of battery fluid.
• While using the unit, the battery compartment cover should be closed.

- Environment

Avoid using your RFX-300 in environments where it will be exposed to:

• Extreme temperature
  High humidity or moisture
• Excessive dust or sand
• Excessive vibration or shock

Since the RFX-300 is a precision electronic device, avoid applying excessive force to the switches and buttons. Also take care not to drop the unit, and do not subject it to shock or excessive pressure.

Alterations

Never open the case of the RFX-300 or attempt to modify the product in any way since this can result in damage to the unit.

Connecting cables and input and output jacks

You should always turn off the power to the RFX-300 and all other equipment before connecting or disconnecting any cables. Also make sure to disconnect all cables and the AC adapter before moving the RFX-300.

Usage Precautions

- Electrical interference

For safety considerations, the RFX-300 has been designed to provide maximum protection against the emission of electromagnetic radiation from inside the device, and protection from external interference. However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves should not be placed near the RFX-300, as the possibility of interference cannot be ruled out entirely.

With any type of digital control device, the RFX-300 included, electromagnetic interference can cause malfunctioning and can corrupt or destroy data. Care should be taken to minimize the risk of damage.

- Cleaning

Use a soft, dry cloth to clean the RFX-300. If necessary, slightly moisten the cloth. Do not use abrasive cleanser, wax, or solvents (such as paint thinner or cleaning alcohol), since these may dull the finish or damage the surface.

Please keep this manual in a convenient place for future reference.

Recording (1) (Insert)

Rhythm machine, synthesizer or similar

This is an example for connecting the RFX-300 between a multitrack recorder (cassette MTR, MD MTR or similar) and a sound source (microphone, guitar, rhythm machine or similar). Monaural sound sources should be connected to the INPUT L/MONO jack. Stereo sources should be connected to the INPUT L and R jacks. In this configuration, the signal from the microphone or instrument

can be sent to the input of the multi-track recorder after effect processing. The balance between original sound and effect sound is adjusted at the RFX-300.

Recording (2) (Send/Return)

This is an example for connecting the RFX-300 to the send/return jacks of a multi-track recorder. Connect the send jack of the MTR to the INPUT L/MONO jack of the RFX-300, and connect the OUTPUT L/R jacks of the RFX-300 to the return jacks (or the stereo line input jacks) of the MTR.

In this configuration, the RFX-300 should be set its outputs send only the effect sound, and the balance between original sound and effect sound is adjusted at the multi-track recorder. If the multi-track recorder is equipped with stereo send jacks, it is also possible to input a stereo send signal to the RFX-300.

Mixdown

This is an example for processing the master L/R output of a multi-track recorder with the RFX-300 and performing mixdown (mixing multiple tracks onto two final stereo tracks) on a master recorder (MD, DAT, or stereo cassette). The balance between original sound and effect sound is adjusted at the RFX-300.

Live Performance

To Operate the Unit on Batteries

Besides using an AC adapter, the RFX-300 can also be powered from six IEC R6 (size AA) alkaline batteries. When the unit is running on battery power, the POWER indicator on the top panel begins to flash when the batteries

②MIX control

Adjusts the mixing ratio of original sound and effect sound, and also serves to adjust other parameters. Which parameter this is depends on the currently selected effect.

For information on effects and adjustable parameters, please refer to page 7.

③ VARIATION/TAP key

This key is used to select effect variations and it also serves for the "tap input" function by which the unit detects the key-press interval. The key operation depends on the currently selected effect.

When VARIATION indicator is lit

Lit O

VARIATION TAP

Each push of the key toggles between variation 1 (VARIATION/TAP key is out) and variation 2 (VARIATION/TAP key is lit).

When TAP indicator is lit

Time-based parameters such as delay time or flanger modulation cycle can be easily input by tapping the key in the desired interval (tap input).

(1) After TAP key is pressed for the first time...

(2) Time until TAP key is pressed for the second time is measured, and the parameter is set accordingly.

If the key-press interval is larger than the maximum possible setting for the current parameter, the parameter is set to the maximum value of the tap input range.

Using the Bypass Function

The effects of the RFX-300 can be temporarily turned off. This is called the bypass mode.

1. To set the RFX-300 to the bypass mode, press the BYPASS key.

The RFX-300 has two different bypass states, depending on the currently selected effect. (For information on which effects use which bypass type, please refer to pages 7 - 11.)

WET MUTE

In this condition, only the effect sound is muted. The effects (A1 - A9) using the connection as described in "Recording (2) (Send/Return)" on page 4 operate in this way. The original sound output

level depends on the MIX control position.

In bypass mode...

- DRY THRU

The original sound is output without any processing. The setting of the MIX control has no effect.

2. To return the RFX-300 to the normal state, press the BYPASS key once more.
