The Dunlop UV-1SC Uni-Vibe Stereo Chorus is an analog rotating speaker effect designed to replicate the legendary tones of the 1960s and early 1970s. It offers both mono and stereo sound capabilities, providing a rich and full sound.

Function Description:

The Uni-Vibe Stereo Chorus creates a chorus/vibrato effect, reminiscent of a rotating speaker. It can be used in a mono configuration or a wide stereo mode.

Important Technical Specifications:

Power: The unit operates on a 9-volt DC power supply. It is designed to be externally powered by the Dunlop ECB02 AC Adapter, which is a 9-volt regulated adapter with a 3.5mm positive tip.
Battery: The device can also be powered by a 9-volt transistor radio battery. It is shipped from the factory without a battery to prevent damage from leakage.

Usage Features:

The device features several controls on its front panel and connectors on its side panel for versatile use:

Front Panel Controls:

Effect/Bypass Switch: This switch toggles between the effect being active and bypassed. A red LED pulsates at the rate of the effect's speed when the effect is on, providing a visual indicator.
Speed: This knob controls the rate of the chorus/vibrato effect. The speed can be adjusted from an almost imperceptibly slow rate to approximately eight times per second.
Mix: This control adjusts the blend of the dry signal and the effect.
- When the "LEFT/CHORUS" output is used: Fully clockwise, it engages the MONO CHORUS mode. Fully counter-clockwise, it outputs a dry signal.
- When the "RIGHT/VIBRATO" output is used: Fully clockwise, it engages the MONO CHORUS mode. Fully counter-clockwise, it outputs a VIBRATO effect, which bends the pitch up and down, creating a quivering texture.
- When both outputs are used: Fully clockwise, it engages the MONO CHORUS mode with a centered sound image. Fully counter-clockwise, it engages the "WIDE" Stereo mode.
Intensity: This knob adjusts the depth or prominence of the chorus/vibrato effect on the signal. It is recommended to adjust this control gradually to understand its impact.

Side Panel Connectors:

Input Jack: This is where you connect a cable from your instrument or other effects in your signal chain.
Power Input: This jack is for connecting the Dunlop ECB02 AC Adapter.
Left/Chorus Output: Connect a cable from this output to the input of your amplifier, other effects, or a recording mixer.
Right/Vibrato Output: Connect a cable from this output to the input of your amplifier, other effects, or a recording mixer.

Maintenance Features:

Battery Installation: To install a 9-volt battery, remove the four screws securing the bottom cover of the unit, insert the battery, and then re-secure the cover. This is necessary if an AC adapter is not being used.
Durability: The device is designed for years of dependable service, indicating a focus on quality and longevity.
