A 14-page stapled brochure - DENON’s regular pure-stereo amplifier catalog No.13, July 2005. The headline event is the debut of the PMA-2000AE “Advanced Evolution”, the fourth revision of the PMA-2000 series at ¥150,000 (excluding tax). A lineup of five integrated amplifiers and one tuner, all on DENON’s own Ultra High Current MOS technology - a single push-pull output stage where one UHC-MOS replaces 35 conventional MOS-FETs: the flagship PMA-SA1 at ¥660,000 with a full-balance design and a natural-wood volume knob, PMA-SA11 at ¥360,000, the new PMA-2000AE at ¥150,000, PMA-1500RII at ¥68,000 in gold and black variants, the bestseller PMA-390IV at ¥39,800 (also in two colors), and the TU-1500 FM/AM tuner with AM-stereo support at ¥33,000. On the back cover - a comparison table of all five amplifiers across 12 parameters, plus a curious panel about the brand renaming: in 2001 the old 日本コロムビア “デンオン” (Denon in the old transcription) officially became デノン (Denon in the modern form), and the catalog itself is already issued under デノン コンシューマー マーケティング.
- UHC-MOS (Ultra High Current MOS) FET - Ultra High Current MOS - DENON's own amplifying device, one UHC-MOS replaces 35 conventional MOS-FETs or 3 bipolar transistors. Single push-pull output stage instead of paralleled stages. On all 5 amplifiers in the catalog
- INVERTED Σ BALANCE 回路 - Inverted Σ Balance circuit on PMA-SA1 - balanced signals from input feed the power stage directly without conversion, for a full-balance design
- カスコードブートストラップ接続 - Cascode bootstrap connection - stabilizes voltage and contact capacitance of the UHC-MOS under heavy current
- 砂型鋳物製トランスケース - Sand-cast non-magnetic ceramic cases for the transformer and condenser holders on PMA-SA1, a technology from the late-90s S1 series, dampens vibration
- L.C. (Leakage Cancelling) マウント・ツイントランス - Leakage Cancelling mount twin transformers - two transformers placed in parallel cancel each other's leakage flux electromagnetically, on PMA-2000AE and PMA-1500RII
- EXTENDED HIGH-FREQUENCY RANGE - Bandwidth extended to 100 kHz - each stage (volume, tone, power amp) reworked to suppress internal noise at ultra-high frequencies, for SACD and DVD-Audio source material
- 6ブロック・セパレーテッド・シャーシ - 6-block separated chassis - the cabinet is divided into 6 sections (equalizer/input, voltage amp, power amp, power supply, control) with steel and copper-plated shielding, on PMA-SA1, PMA-SA11, PMA-2000AE
- S.L.D.C. (Signal Level Divided Construction) - Signal Level Divided Construction on PMA-390IV - small-signal, large-signal and microcontroller circuits separated to eliminate cross-interference
- AMステレオ対応 - AM Stereo support on the TU-1500 tuner - for receiving AM-stereo broadcasts of sports coverage
