Fisher CP-100 (c. 1971–1972)
Fisher's answer to the cartridge player that didn't sound like a toy. It was a $169.95 quadraphonic 8-track deck built for people who already owned good components.
Overview
The Fisher CP-100 was a cartridge deck aimed at the component-stereo crowd. Fisher's own advertising made the pitch bluntly: ordinary 8-track players, the company argued, simply didn't have the audio quality that owners of fine component systems demanded. The CP-100 was the reply. It was an 8-track tape cartridge player with four separate channels, and it sold new for $169.95 in 1971. The period ads in High Fidelity (June 1971, p.2) and HiFI-Stereo (June 1971, p.2) ran the same framing. They positioned the deck as component-grade tape playback rather than a car-player afterthought.
The CP-100 carried four separate channels for quadraphonic playback, but it also played ordinary stereo cartridges. The switch between 4-channel and 2-channel modes was fully automatic, not a manual toggle. Red jewel lamps on the front panel showed which mode was active. A High Fidelity equipment directory entry (April 1972, p.59) listed it plainly as a "4-channel 8-track tape cartridge player" with four separate channels. That is about as much independent confirmation as the model ever got.
The deck was built for a market that, in the early 1970s, had few serious options. Fisher intended it to bring quadraphonic tape into a Fisher-based component system, and period advertising routinely showed the CP-100 alongside the company's Model 601 receiver. The two were sold as a natural pair. What survives is mostly that advertising and the directory listings. No service manual, schematic, or detailed spec sheet has surfaced in the usual collector databases. So the numbers a modern buyer would want most - frequency response, wow and flutter, channel separation - aren't documented anywhere the Archive can find.
Key Features
Four Separate Channels with Automatic 2/4-Channel Switching
The CP-100's headline capability was quadraphonic playback across four separate channels, confirmed by the High Fidelity directory listing (April 1972, p.59). Owners didn't have to commit to quad, though. The deck switched automatically between 4-channel and 2-channel playback, and red jewel lamps on the front panel showed which mode was live. That is handy on a deck sitting in a dim listening room. Fisher's advertising described the switch between correct modes as completely automatic, indicated by those lights.
Ambient Extraction Circuit
For listeners with a shelf full of ordinary stereo cartridges and no quad software, Fisher built in a front-panel switch. It activated a circuit that extracted ambient information from two-channel material, synthesizing a simulated four-channel effect out of stereo tapes. Nobody buys a quad deck without quad tapes, so this let the deck make quad from what the owner already had. The surviving documentation doesn't say how well the effect worked.
Push-Button Electronic Program Selection
Program selection on a standard 8-track cartridge means choosing among four programs. The CP-100 did it with push-buttons and electronic switching rather than mechanical moving parts. That matters on 8-track gear, where mechanical program-switch mechanisms were a known source of grief. The electronic approach sidesteps the moving parts entirely. Fisher's advertising made the point explicitly, contrasting the CP-100's push-button electronic tuning with the mechanical schemes used elsewhere.
Playback-Only Dedicated Deck
Available documentation describes the CP-100 as a dedicated playback deck. No recording capability is mentioned in any of the surviving period material. That is an absence of evidence, not a confirmed spec, but nothing in the advertising or directory listings suggests the machine recorded, and it was sold as a player.
Historical Context
The CP-100 arrived in the first flush of quadraphonic enthusiasm, and Fisher slotted it into the component market rather than the mass-market cartridge scene. The company's advertising in High Fidelity (July 1971, p.2) and HiFI-Stereo (July 1971, p.2) plugged the deck directly into the Model 601 receiver, framing the pair as a complete quadraphonic front end. The CP-100 also turned up in Audio (September 1971, p.39). The High Fidelity equipment directory (April 1972, p.59) carried it alongside Fisher's other 4-channel components - the 801 and 601 receivers, the TX-420 converter, and the Fisher 40 music center - which shows where the deck sat in the lineup.
Production is generally placed around 1971 to 1972, though the exact start and end dates aren't confirmed in surviving sources. The record does establish a $169.95 list price in 1971 and a steady advertising presence across the major audio magazines of that year and the next.
