AC Adapter Precautions Warnings The supplied AC adapter is designed only for Zoom products with an input rated for 9 V DC, 300 mA, center minus. Never use the adapter for any other product or purpose. ¥ Using the adapter with a product that requires a different voltage or polarity poses a risk of fire and electric shock.

When using the Vocoder effect, the signal from the microphone input becomes the effect envelope signal. If you wish to use a microphone other than offered by Zoom, choose a dynamic microphone with an impedance of 600 ohms.
Note: A preamplifier (such as integrated in a mixer) or a compact effect device is required when wishing to use the 1204 with an instrument with low output level, such as an electric guitar or bass, or with a high-impedance instrument (470 kilohms or...
Connections Connect an electronic instrument, microphone, mixer, or other audio equipment to the 1204 as described below. Before making any connections, set the power switches of all equipment to OFF. Precaution If the equipment is on, sudden noise surges can lead to hearing damage or damage to the equipment.
This connection example shows use of the 1204 as an effect device for vocals. Use a dynamic microphone with an impedance of 600 ohms. Plug the microphone into the MIC IN jack on the front panel of the 1204. If connected to a rear-panel INPUT jack, the volume level will not be sufficient.
Rack Mount • This unit uses a metal enclosure and is heavier than it might seem at first glance. When mounting the unit in a rack, be sure to fasten it securely with screws, and use a rack that provides sufficient rigidity. If the unit is not secured properly, it can fall down and cause damage and injury.
The 1204 has various operation states. Basically, there are three modes and three functions. Modes • Manual mode: In this mode, the front-panel controls and switches of the 1204 operate as shown on the unit, letting you directly select and use effects.
To select a stored setting, the front-panel signals can be used. It should be noted that selecting a setting that is stored in the memory of the 1204 makes that setting active but does not change the mechanical position of the front-panel controls. Therefore in memory mode it is possible that the front-panel controls indicate for example the FLANGER effect although the HALL effect is active.
Effect on/off function The 1204 allows the user to quickly turn off all effects, so that only the original (DRY) sound is output. Effect on/off switching is normally performed using the EFFECT key on the front panel of the 1204, but in memory mode it can also be controlled by external MIDI equipment.
5. Adjust the MIX LEVEL control of the 1204 for the desired balance between DRY and WET sound. 6. Adjust the OUTPUT control of the 1204 and the input level control of the playback system or mixer return input to a suitable position.
Turning effect processing on and off Normally, when the 1204 is turned on, effect processing is automatically enabled. This is called the "effects on" or "active" condition. In this condition, the EFFECT indicator is lit. Temporarily disabling effect processing is called the "effects off"...
1204, so that you do not have to make the same adjustments every time you want to use this setting. The memory capacity of the 1204 is sufficient for up to 100 settings. Once a setting has been stored, it can be called up quickly, using the memory mode of the unit.
Stored effect settings can be called up in the memory mode.Selecting a setting that is stored in the memory of the 1204 makes that setting active by electrically controlling the DSP (Digital Signal Processor) in the unit, but it does not change the mechanical position of the front-panel controls including the BANK switch.
Editing a stored setting The memory mode normally serves to call up effect settings stored in manual mode. However, when wishing for example to slightly alter a parameter or to change only the EQ setting of an effect and store it in another memory number, it is not necessary to switch to manual mode and start the adjustment over from the beginning.
1. Connect the MIDI OUT jack of the external device to the MIDI IN jack of the 1204. Turn all devices off before making this connection. 2. When connections are established, turn on the devices and use the MODE key of the 1204 to set it to the memory mode.

Cleaning Use a soft, dry cloth to clean the 1204. 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.
