Dynacord DRS-78

Not much is documented about the Dynacord DRS-78. The fullest record is a technical review in Studio Sound (October 1979, p.82). It measured the unit's output levels and published a frequency-response curve taken from the front-panel input, through the input equalisers, to the "original" output. The measured levels were:

• Original output, left/right: −6 dBV
• Original output, mono: 0 dBV (1.0 V)
• Mixed output, left/right: +3.5 dBV (1.5 V)
• Mixed output, mono: +6 dBV (2.0 V)
• Delay output, left, right, and mono: 0 dBV (1.0 V)

The dedicated delay and mixed outputs suggest a processor that could blend a dry signal with a delayed, equalised one. Without a manual or catalogue copy, though, Dynacord's own description of the unit is not confirmed.

An advertisement in Modern Recording (September 1978, p.57) appears to introduce the DRS-78 among a batch of new Dynacord systems. The surviving copy is badly garbled. Dynacord's own advertising later in that magazine (December 1982, p.13) called the company Europe's leading professional sound-reinforcement manufacturer - useful brand-era context, but nothing DRS-78-specific. No production dates, original prices, or other documentation have surfaced.
