HHB Communications is a British-based

firm specializing in digital audio record-

ing equipment and media for the profes-

sional audio industry. In addition to CD

recorders, HHB manufactures portable

DAT recorders, a line of vacuum-tube

processors (including mike preamps,

compressors, and parametric equalizers),

and studio monitor loudspeakers (includ-

ing nearfield monitors and powered sub-

woofers). HHB also distributes the Genex

line of high bit rate, high sampling rate

magneto-optical digital recorders. Their

complete line of digital media includes

professional-quality recordable compact

discs (CD–R), ADAT tapes, MiniDiscs

(MD), and rewriteable magneto-optical

(MO) discs.

The CDR–800 Compact Disc

recorder (Photo 1) has been on the

market for over two years. At the time it

was introduced, the CDR–800 repre-

sented a price breakthrough in profes-

sional CD recorders. The list price of

$2200 has become irrelevant, since the

unit now sells for around $1200 at most

pro audio dealers.

The CDR–800 looks suspiciously like

the Pioneer PDR–05 and PDR–99 con-

sumer CD recorders, which are essential-

ly identical—the PDR–99 is marketed as

part of Pioneer’s Elite line, and features

their glossy Urushi front panel and Rose-

wood side panels. While based on the

consumer models, the CDR–800 is actu-

ally manufactured by Pioneer for the pro-

audio user, and incorporates a number of

features not found on the consumer

units. The Pioneer consumer players

have only unbalanced (RCA) analog in-

puts and outputs, along with S/PDIF and

Toslink digital inputs and outputs. To

these interfaces, the CDR–800 adds bal-

anced XLR analog inputs, along with a

balanced XLR AES/EBU digital input

(Photo 2).

All analog and digital outputs on the

CDR–800 remain unbalanced. This may

appear odd at first, but most pro audio

users are likely to use the CDR–800 with

an external digital processor for play-

back, making balanced analog outputs

unnecessary. One other important differ-

ence between the CDR–800 and its Pio-

neer counterparts concerns the types of

recordable CDs you can use. The Pioneer

consumer machines will only recognize

consumer-type CD–R blanks. The

CDR–800 will also work with computer-

type CD blanks. The CDR–800 is also

equipped with standard 19-inch rack

mounts.

One important feature of the

CDR–800 is Pioneer’s Stable-Platter

mechanism (Photo 3), which includes a

full-size platter upon which the CD is

placed upside down. There are a couple

of advantages to this system. First, the

disc is supported over its entire surface,

minimizing vibration, which, in turn,

should reduce clock jitter. This serves

the same purpose as the disc dampers

many of us have used, but Pioneer’s solu-

tion is far more effective. Second, the

laser now faces down, so it is far less like-

ly to accumulate dust.

Operation

Operationally, the HHB CDR–800 is ex-

tremely well thought out, and is really

not much more difficult to operate than

an analog cassette deck. For the most
