FEATURES

Your Radio Shack SSM-1000 Audio Mixer with Echo is a sophisticated control center for recording from multiple playback sources such as a CD player, tuner, turntable, or VCR, or from live performances. A seven band equalizer and an echo effect are incorporated into the mixer so you can tailor the sound to compensate for environmental conditions or for personal preference. The mixer’s many features give you almost limitless sound combinations.

Its features include:

7-Band Frequency Equalizer — allows you to tailor the sound output to your preference.

Two Pairs of Stereo PHONO Inputs

— for using turntables with either magnetic or ceramic cartridges.

Stereo Line Inputs — let you connect most high level audio sources, such as a tape deck, amplifier, tuner, or VCR.

Low-Noise Tape Out Jack — for high-quality tape recording.

Slide Controls — for fingertip control of sound mixing and fading adjustments.

Monitor Controls — let you hear and check line inputs using headphones before mixing.

Normal/Standby/Talkover Switch — lets you control when you talk with music, talk over music, or talk without interrupting the music or being heard through the mixer, to give you a “DJ’s” control.

Phono 1/Phono 2 Fader Control — allows you to quickly and smoothly switch between playing PHONO 1 and PHONO 2.

Monitoring Controls — lets you listen to the outputs of MIC, PHONO 1, PHONO 2, LINE 1, LINE 2, or MASTER through headphones.

To obtain best performance of your audio SSM-2200 Mixer, please read this manual carefully before you connect it to other audio components.

For your important records, we recommend you record this unit’s serial number in the space provided. You’ll find the serial number on the bottom of the unit.
