Introducing a new upgrade for the 661 !
Introducing the PLUS MOD for the Marantz PMD-661 & MKII. It can be added to any existing Oade Brothers MOD or installed into a stock machine along with the either FET, Super, Warm or Concert MODs. The stock machine with MIC ATTN set to 0dB and gain adjusted for 55dBV of gain to reach 0DBFS has a noise level of -50dbV. The Super MOD Plus, with the same settings, has -57dB of noise while the FET MOD Plus has a noise floor of -60dBV. This upgrade achieves enhanced performance by removing the internal mics and dual level mono. Please contact Doug Oade for details.
