Marantz PMD 661 24 bit recorder

The Marantz PMD 661 only 599.00 with free 2 day air shipping !

The Marantz PMD 661 Concert MOD upgrade rebuilds the XLR inputs using high speed, low noise and very low distortion op amps that dramatically improve fine detail and clarity. The result is a very detailed, open 3D soundstage. Input PCB capacitors are also upgraded. Components are selected by ear to optimize detail and imaging for recording all types of music where transparency is needed.

The Marantz PMD 661 Warm MOD upgrade rebuilds the XLR inputs using high speed, low noise and very low distortion FET op amps that dramatically improve fine detail and clarity. the Warm MODs preamp chips use FETs so they sound very much like a tube preamp with the warm sound that offers a fat rounded bass tone, a sweet silky high end and the expansive soundstage found in high end tube circuits. Input PCB capacitors are also upgraded. Components are selected by ear to optimize detail and imaging for recording all types of music when a warm tone is needed.

The Marantz PMD 661 Super MOD upgrade rebuilds the XLR inputs using very high speed, very low noise and super low distortion op amps that dramatically improve low level detail and clarity. Input PCB capacitors are also upgraded. Super low THD+N op amps allow for a very wide SFDR even with signal levels down 50dB. This preserves the signal quality of the highest grade microphones when recording soft signals, like voice, un amplified music, nature sounds and FX.

Edirol R44 records uncompressed to an SD or SDHC memory card.







Weighing in at just less than 3 lbs including batteries makes the R-44 a perfect high quality recording solution for videographers, musicians, nature enthusiasts, journalists and sound designers to take anywhere.

The R-44 is a compact, four channel, solid-state field recorder that uses SD or large capacity SDHC cards as the storage media enabling quiet and reliable recording for a variety of professional audio needs. Capture up to 4 channels of uncompressed audio with selectable bit depths (16-bit or 24-bit) and sampling frequencies (44.1kHz/48kHz/88.2kHz/96kHz/192kHz). Onboard effects include limiter, low cut filter, 3-band EQ, 6-band GEQ, Enhancer, and DeEsser.

The Edirol R44 Concert upgrade rebuilds the mic preamps using high speed, low noise and very low distortion op amps that dramatically improve fine detail and clarity. Components are selected by ear to optimize detail and imaging for recording amplified music. Improvements are also made to reduce the audible digital noise that contaminates the analog signal path with noise generated by the display.

The Edirol R44 Super upgrade rebuilds the mic preamps using high speed, very low noise and low distortion op amps that improve intelligibility and low level detail. Components are selected by ear to optimize detail and imaging for ENG, Acoustic Music or Ambient recordings with Ambisonics or Schoeps Surround mics. Improvements are also made to reduce the audible digital noise that contaminates the analog signal path with noise generated by the display, essential for high gain applications.

The chips used for the Super MOD have lower THD than the stock ones (about 9db less) but not as low as the ones used for the Concert MOD. The Super MOD chips do have a bit less hiss than the ones for the Concert MOD. This is preferred for very soft signals as there is less signal to mask the noise. In the Concert MOD the much lower THD chips (about 18dB less than the stock ones) enhance clarity in signals like music. Since music is going to have more signal level than very soft sounds, like nature sounds, the very slightly higher level of hiss is the Concert MOD vs the Super MOD is masked or not audible. The Concert MOD upgrade improves both line level and mic level signals so the Concert MOD is very will suited for use with line level sources, like a recording console or external preamp. To sum up, the Concert MOD optimizes the preamp circuit for clarity while the Super MOD optimizes it for low noise, both offer better detail and clarity than the stock deck.

PMD 620 - small, reliable and professional quality.

The PMD 620 Basic rebuilds the PMD 620 mic preamp with a very low noise, high slew rate op amp that dramatically enhances detail and clarity while lowering noise and audible distortions. This upgrade also increases the mic input gain by 6dB in order to record lower signal levels without using the ALC circuit. All features remain intact.

The PMD 620 Concert rebuilds the PMD 620 mic preamp with a low noise, very low distortion and high slew rate op amp that dramatically enhances detail and clarity while lowering noise and audible distortions. This upgrade also improves the line input circuit. The built in mics are removed to maximize microphone input quality, all other features remain intact.

The PMD 620 Super rebuilds the PMD 620 mic preamp with a very low noise, low distortion and high slew rate op amp that dramatically enhances detail and clarity while lowering noise and audible distortions. This upgrade also improves the line input circuit and increases the mic input gain by 6dB in order to record lower signal levels without using the ALC circuit. The built in mics and plug n power are removed to maximize microphone input quality, all other features remain intact.

Tascam HD-P2 High Resolution 24bit 192KHz Time Code Recorder

The HDP2 High Definition Upgrade rebuilds the analog signal path of the stock HD-P2 using very high slew rate op amps with ultra low THD. This upgrade reduces analog signal path distortion to the A/D chip and removes the limits imposed by the lower grade stock signal path chips. This significantly improves clarity and detail as well as size and depth of soundstage.

The HDP2 Super MOD increases clarity and detail for enhanced performance in ENG, Nature and Ambient recording, FX or any application that requires high gain and low noise. This upgrade gives the HDP2 a clean and fast signal path that is true to the input signal and use a preamp chip with significantly lower THD (25dB lower than the stock chip) 6dB of gain can be added by request, recommended for Nature recording or ENG with dynamic mics.

The HD-P2 Basic MOD rebuilds the mic preamp sing very high slew rate op amps with ultra low THD for enhanced clarity and detail. The Basic MOD HD-P2 is priced at only 999.00
