HHB PortaDAT PDR-1000
A four-head, four-motor location DAT built in consultation with the recordists who'd actually carry it up a hill.
Overview
The PortaDAT's transport has four heads and four motors, derived from DDS data-tape technology. In a portable DAT deck that arrangement exists for confidence monitoring. The machine reads back off tape while it records, so the operator hears what is actually being laid down rather than what the electronics believe is being laid down. For location work, where a ruined take means a ruined day, that is the whole argument in one feature. HHB's own advertising in the period leaned hard on it, billing the four heads and the rugged four-motor transport as the things a professional portable needed. Mix (July 1995, p.69) ran copy praising the build and audio quality. Advertising is not a verdict, but the transport spec behind the claim is real, and it is the reason collectors still seek these out.
Around that transport HHB built a professional connectivity set. Balanced XLR mic and line inputs, AES/EBU and S/PDIF digital I/O, and 48V phantom powering are all onboard, with selectable sampling rates at 44.1kHz, 48kHz and 32kHz. Phantom-powered balanced inputs plus both kinds of digital I/O in a battery-portable box is what separated the PortaDAT from the consumer DAT portables of the era.
Power is the other distinctive engineering choice. The PDR-1000 runs on Nickel Metal Hydride rechargeable battery technology, which HHB positioned as giving the machine longer running time than other portables. NiMH has no memory effect, so careless charging routines couldn't quietly strangle the pack the way they could with older cells. The machine was developed over a two-year research and development programme, and HHB was explicit that it was designed and engineered around the demands of location sound recording rather than adapted from a studio deck.
Two versions shipped. The base PDR-1000 is the straight location recorder. The PDR-1000TC adds the ability to record, generate and reference timecode in all existing international standards, plus jam sync and conversion of Absolute Time to Time Code. The TC variant is the one post-production and sync-critical location work wanted, and it's the version that commands attention on the used market today.
The launch was not a quiet one. HHB unveiled the PortaDAT at the New York AES show, and among the first customers for production units was the BBC's Outside Broadcasts Radio Unit. The BBC took delivery of a quantity for a summer schedule that included the World Cup and the Commonwealth Games. HHB's broadcast sales manager noted at the handover that the first production units going to the BBC was fitting, given how much input BBC engineers and producers had contributed during development.
Mix (July 1995, p.69) carried HHB's claim that the PortaDAT offered the features, audio quality and rugged construction serious users required — again, manufacturer copy, so read it as positioning rather than independent testing. What the period trade press does confirm independently is the machine's standing: by the late 1990s HHB's own advertising was calling PortaDAT the industry standard in location DAT recording, and the range was still being actively supported with new accessories. Studio Sound (October 1996, p.89) announced an HM1000 Headphone Matrix, a TCP1000 timecode upgrade path for existing PDR1000 owners, and an MCA1000 four-bay fast charger for the NiMH packs — evidence of a platform HHB intended to keep in the field rather than replace.
The upgrade path is the detail that makes the PDR-1000 interesting to collectors now. HHB announced that existing PDR-1000 owners could bring their machines up to full PDR-1000TC timecode specification - record, generate and reference timecode in all existing international standards - for $3,995. In the UK the upgrade was priced at £2,250 and made available from the end of August 1995, announced in response to customer demand. Because a factory-sanctioned upgrade route existed, a plain PDR-1000 in the wild may or may not have been converted. A seller's claim of TC capability is worth checking against the machine itself.
For anyone buying one today, the battery system is now decades old. The NiMH packs and the MCA1000 charger were designed as a system, so a machine that arrives without a working pack or charger needs some other way to power it. The four-head transport is the reason to own one and also the reason to have it serviced by someone who knows DAT transports. Confidence heads are not a consumer-grade arrangement, and alignment matters.
The PortaDAT is a working recorder built for people who needed to trust the tape in a hostile environment. It has balanced inputs, phantom power, digital I/O in both standards, a transport that lets you hear the recording as it happens, and a battery chemistry with no memory effect.
