A range of signal splitters and headphone splitters, two, three, four and eight way, some with volume controls.
A tough plastic box houses the PS-4 Splitter, which has one stereo jack input on the back, feeding 4 stereo jack outputs. The sockets are pcb-mounted, and there is an internal link to mono the unit.
Used, for example, for splitting headphone signals in music rooms, classrooms, computer music recording systems and hi-fi systems, it can also work in reverse as a 4 into 1 passive combiner.
The dimensions are 120 x 75 x 39 mm., weight 12 grams.
Another version, the PS-4v, has two additional volume controls, operating on channels 1 and 4. These are handy for balancing headphones of differing impedances (and thus different volumes), or ears with different sensitivities.
The PS-8 is an 8 output version in an all-steel, RF shielded box. Dimensions: 208 x 73 x 44mm. Weight 60 grams.
The PS-8v has volume controls on channels 1, 4, 5 and 8, better for use with headphones of differing impedances. All outputs on all models are fully protected by a 10 ohm resistor. Size as PS-8, weight 65g.
Another variation, the PS-435, is a mini-jack version of the PS-4. It features a 1 metre captive input lead fitted with a 3.5mm stereo jack, and four 3.5mm stereo jack socket outputs. Perfect for 3.5mm computer card or keyboard outputs and minijack headphones.
And finally, if it is only necessary to have a two-way split with very light duty use, the AL-22S is a short splitter cable to enable two pairs of headphones to connect to a single output. It is generally agreed that the rigid ‘Y’ type of adaptor puts considerable strain on the output socket and that a short flexible lead, as in this design, is far less likely to cause problems over time. Specs: 6.3mm stereo jack plug to 2 x 6.3mm stereo jack sockets. Length: 200mm.
