Goldpoint SA4M dual mono passive preamplifier. Individual left and right channel volume control. Four stereo input channels and one stereo output channel. it is in working condition and is from an estate.

The Goldpoint SA4M (dual mono volume controls) easily out perform other passive preamplifiers. Along with superior clarity, transparency, and precision, they also provide the flexibility of a selectable Auxiliary Input/Output RCA jack set. 100% passive, they were designed to improve sound quality while replacing (often unnecessary) active preamplifiers. No distortion is added to your signal path while performing level control. (Active preamps add in at least some distortion.) 4-position selector switch allows level control for multiple signal sources. Versatile AUX Input allows easy rewiring (two internal wire jumpers) for alternative preamp functions. Goldpoint precision stepped attenuator for low noise and excellent channel-to-channel signal level matching. Volume Control: SA4: Goldpoint Stereo V24 Stepped Attenuator, with precision 0.5%, thin film resistors. SA4M: Two Goldpoint Monaural V24 Stepped Attenuators, with 0.5%, thin film resistors. Selector Switch: Goldpoint 2P-4T-1D. Inputs & Outputs: Four sets of Stereo Inputs and one set of Outputs. LINE IN 4 / AUX is easily configured for alternate use by re-positioning 2 internal wire jumpers. 1) Fourth Line Input (factory default). 2) Tape Output. 3) Main Output #2. Rear Panel RCA Jacks: Gold-plated, heavy duty solid brass, right angle PC board style. Wiring: High grade, silver-plated copper, multi-stranded, with Teflon jacketing. Chassis: Aluminium clam-shell, sandblasted and black anodized, 1/4 front and rear panels. Dimensions: 2.3 Tall x 6.2 Wide x 7.0 Long Weight: approx.: 1 3/4 lb. The SA4 makes it hard to believe you could do any better at all with an active unit. Any disadvantages in gain, or dynamic headroom are far outweighed by the crispness, clarity, focus and transparency all at a small fraction of the cost. 24 positions are more than enough and the unit has a great “feel”.
