BSR EQ-3000 10-band Stereo Equalizer and Spectrum Analyzer

The BSR EQ-3000 is a 10-band Stereo Equalizer and Spectrum Analyzer. It provides up to +/- 15 dB boost/cut. The analyzer has a range switch to provide either a 20 or 30 dB range.

The EQ-3000 also functions as a dubbing switch to allow recording either way between 2 “tape recorders” or other stereo record/playback devices. It is designed to connect to a home stereo's tape in/out and provide access to 2 recorders instead of just 1.

In addition to the EQ sliders. front panel controls include:

• Meter switch to monitor L, L+R, or R channels

• Meter range switch (20 dB or 30 dB)

• Meter sensitivity control

• EQ in/out switch

• Hold button to freeze the display

• L and R attenuators to control playback volume

• Dubbing switch (1>2, Source, 2>1)

• Monitor switch (1, Source, 2)

• Pink Noise switch (I do not have the calibrated microphone)

• Subsonic filter (-18 dB below 15 Hz to eliminate turntable rumble)

• Line/Mic switch (in line position analyzer measurements are made from the line outputs)

The rear panel has RCA jacks for left and right inputs and outputs for 2 record/playback devices and for connection to a monitor system.
