The 1176SA™ calibrates two mono 1176s for stereo operation. The 1176SA was first offered for the original 1176, but has become increasingly difficult to find for use with either vintage or new 1176s. Due to customer demand for stereo operation, we carefully recreated the original adapter. The 1176SA is a small device (4.25" x2.5" x1.75") which rests behind the 1176s. The 1176SA sports a full metal enclosure for proper shielding, gold-plated connectors. A 2-year battery is included. The 1176SA is compatible with both new and vintage models.
