CROWN
Crown International — United States
Crown occupies a distinctive place in American open-reel history. Its professional and semi-professional tape machines were engineered around unusually robust transports, modular electronics and long-service reliability. Crown’s Pro 800 Series introduced logic-controlled transport operation by the late 1960s, while earlier Crown machines established the company’s reputation for durable recording equipment. (Museum of Magnetic Sound Recording)
For the OpenReelToReel reference, Crown is best treated as an American professional/semi-professional manufacturer, not simply a domestic hi-fi brand.

Wow & Flutter
Published figures include approximately:
15 ips: 0.06%
7½ ips: 0.09%
3¾ ips: 0.18% (Radiomuseum)
Transport
The 822 family uses an unusually heavy-duty mechanical design. On documented examples, switching between the lower two speeds is performed from the machine controls, while selecting 15 ips involves moving the capstan-drive belt to the appropriate pulley. (Vintage Listening)
Although inelegant by later electronic standards, the arrangement is mechanically straightforward and characteristic of Crown’s durability-first engineering philosophy.

- 2-track stereo format
- 15 ips capability
- 10.5-inch reel capacity
- Three-head configuration
- Solid-state electronics
- NAB equalisation

Collector Notes
The Crown CX-822 is one of the most interesting American alternatives to the better-known European Revox and Studer machines.
Its combination of:
¼-inch tape + 2-track stereo + 15 ips + NAB EQ + 10.5-inch reels
makes it significantly more relevant to modern audiophile master-tape use than many highly collectible four-track domestic decks.
For NAB-format 15 ips tapes, a correctly aligned CX-822 can be a genuinely serious reproduction machine.
The principal limitation for present-day ownership is not basic engineering quality, but restoration support and parts availability.
Buyer Inspection
Check:
- capstan belt;
- 15 ips pulley arrangement;
- pinch roller;
- braking system;
- reel motors;
- transport logic;
- head wear;
- head alignment;
- NAB equalisation calibration;
- record bias;
- electrolytic capacitors;
- switches and relays;
- meter accuracy;
- remote-control circuitry;
- previous modifications.

Collector Notes
The SX-822 is especially attractive for enthusiasts whose priority is serious stereo 15 ips tape reproduction without moving directly into large studio-console machines.
Properly restored machines can be aligned for contemporary mastering tape formulations, but any purchase should be judged on the actual restoration and calibration rather than merely the cosmetic condition.
A documented restored SX-822 has been calibrated for ATR Magnetics Master Tape, demonstrating that these transports remain viable with modern professional tape stock when maintained correctly. (reverb.com)
Master-Tape Suitability
For modern:
¼-inch
2-track
15 ips
NAB
master-tape releases, the SX-822 architecture is highly relevant.
For IEC/CCIR 15 ips releases, suitability depends upon the electronics/equalisation configuration or appropriate modification.

CROWN SS-824
Manufacturer: Crown
Model: SS-824
Country: United States
Introduced: 1964
Type: Solid-state stereo reel-to-reel recorder
OpenReelToReel Class: HISTORICAL PROFESSIONAL / COLLECTOR CLASSIC
Crown specialist archival research dates the introduction of the SS-824 to August 1964 and identifies it as Crown’s first solid-state machine. (Reel to Reel)
Historical Importance
This model marks a major technological transition in Crown’s recorder history:
Tube Electronics → Solid-State Electronics
The SS-824 therefore deserves a high historical score even if later Crown machines provide greater practical appeal for modern master-tape playback.
Engineering Character
- Early Crown solid-state design
- Heavy-duty transport architecture
- Professional/semi-professional orientation
- American modular construction
- Transitional model between Crown’s tube era and later Pro 800 machines

Collector Notes
The SS-824 is important because it captures Crown at the moment the company moved into solid-state professional tape electronics.
Collectors should resist comparing it only by frequency-response figures with machines made a decade later. Its significance lies equally in:
- engineering development;
- Crown history;
- American professional recorder design;
- mechanical durability;
- transitional electronics.

CROWN PRO 800 SERIES
Manufacturer: Crown International
Country: United States
Era: Late 1960s–1970s
Type: Professional / semi-professional recorder family
OpenReelToReel Class: PROFESSIONAL CLASSIC
By 1968 Crown’s Pro 800 family incorporated a logic-controlled transport, an important development in the company’s recorder engineering. (Museum of Magnetic Sound Recording)
Original Crown operation/service documentation covers the Pro 800 Series as a family rather than one single immutable specification, so the database must retain model suffixes rather than collapsing the whole series into one entry. (Technical Audio)
CROWN MODEL-NUMBER WARNING
This is particularly important with Crown.
Names such as:
CX-822
SX-822
SX-824
CX-828
SX-844
CX-844
encode meaningful configuration differences.
The numbers and prefixes can correspond to different:
- track formats;
- channel arrangements;
- electronics;
- record/reproduce capabilities;
- remote functions;
- speed arrangements.
Therefore:
DO NOT ASSUME THAT ALL CROWN 800-SERIES MACHINES ARE 2-TRACK 15 IPS RECORDERS.
Every individual model and surviving machine must be checked.
CROWN CX-828
Manufacturer: Crown International
Country: United States
Family: Pro 800
OpenReelToReel Class: SPECIALIST PROFESSIONAL
Available Crown documentation confirms that the CX-828 belongs to the CX family with remote-record capability. (Tea Remotes)
Because precise track geometry and electronics vary within this family, the complete technical record should remain flagged until the original model-specific manual/schematic is transcribed.

CROWN CX-844 / SX-844
These models must be entered independently in the final database because the Crown naming system distinguishes differing electronics and record-control capability.
Both CX and SX 844-family machines are documented in Crown remote-control information, with CX-844 supporting remote record while SX-844 does not provide the same remote-record function. (Tea Remotes)

EARLY CROWN 800 SERIES — TUBE ERA
Before Crown’s solid-state machines, the company produced serious tube-based recorders associated with early 800-series transports.
Specialist archival research identifies early B- and C-series transports paired with RP-3 tube electronics, including stereo systems using two mono electronic channels. (Reel to Reel)

Modern Practicality: ★★★☆☆
Parts Availability: ★★☆☆☆
Collector Rarity: ★★★★★
Historical Importance: ★★★★★
These machines deserve separate future records because their architecture differs substantially from later solid-state Pro 800 systems.
CROWN — MASTER-TAPE REFERENCE ASSESSMENT
Within the Crown family, the machines of greatest immediate interest for modern master-tape users are the properly configured:
CROWN CX-822
Master-Tape Playback: ★★★★½
CROWN SX-822
Master-Tape Playback: ★★★★½
Why not an automatic five stars?
Because modern master-tape suitability requires more than 15 ips.
The individual machine must match:
- ¼-inch tape
- 2-track stereo geometry
- 15 ips
- appropriate NAB or IEC/CCIR EQ
- correct reference fluxivity
- correct azimuth
- correct playback level
- low head wear
- proper transport tension
- professional calibration
With these conditions satisfied, the Crown 822 family can be an extremely serious analogue reproduction platform.

OPENREELTOREEL COLLECTOR VERDICT — CROWN
Crown reel-to-reel machines are sometimes overshadowed by:
Studer
Revox
Ampex
Otari
Nagra
Telefunken
but they deserve inclusion among the most serious American open-reel designs.
The best Crown machines combine:
massive construction
simple but rugged engineering
professional tape speeds
large reels
2-track capability
service-oriented architecture
excellent restoration potential
Their greatest modern disadvantage is scarcity of specialist parts and technicians, not lack of fundamental engineering quality.
For an enthusiast playing 15 ips, ¼-inch, 2-track NAB master tapes, a fully restored and correctly aligned Crown CX-822 or SX-822 can be considerably more appropriate than many famous Japanese four-track collector decks.
