Glasshouse Passive Pre-amplifier No.1 Kit

Glasshouse Passive Pre-amplifier (without stepped attenuator, available in black only)

Due to the massive variety of stepped attenuators we have created over the years, featuring different types of switches, resistors and load resistors, we have decided to sell the pre-amp kit without the stepped attenuator. So it is necessary to order a stepped attenuator as well. All the different types we sell.

The chassis design keeps all signal wire lengths as short as possible. Passives are not good at driving long interconnect runs, so the distance from the inputs - selector - volume control device - output socket is vital.

Dimensions (with feet and knobs fitted)- 85mm(h) x 185mm(d) x 150mm(w)

The Glasshouse chassis is made of 2mm thick aluminium, black powder-coated, with a matt black plastic front panel and black anodised aluminium knobs. The front panel is a 6mm thick matt-finished plastic plate with etched screenprint markings. The chassis is non-ferrous with shielding properties, so there is limited interaction with nearby separates. The finished product weighs in at 1kg to stand firm during switching.

Our passive has six pairs of RCA inputs, one pair of RCA record outputs and two pairs of output RCA sockets. There are plenty of inputs for multi-source systems, and you can feed a subwoofer and satellite systems with the extra output.

The parts included in this kit include an Elma switch, gold-plated RCA socket and gold-plated earth post. Additionally, we have Neotech UP-OCC 1/0.3mm copper wire and 3.8% silver solder from Mundorf.
