With the ACRO CA1000T, you can pick and choose from seven DAC filters to create your own EQ/style. Design your own sound with the seven DAC filters.

• Minimum phase (Default):  Low latency minimal preringing and low-pass ripple wave
• Linear Phase Apodizing: Full image rejection by FS/2 to avoid any aliasing, with smooth roll-off starting before 20 kHz wave
• Linear Phase Fast Roll-Off: Most common filter with clean suppression and high rejection, best for music with high transients. Provides crisp clean highs wave
• Linear Phase Slow Roll-Off: Low group delay and symmetrical inputs response. Less ringing than Linear Phase, fast roll-off. Punchier bass than LPFR, with clean highs wave
• Minimum Phase Fast Roll-Off: Minimal preringing, preferred for imaging and soundstage. No aliasing in frequency domain. Stronger bass than Linear Phase, clean high waves
• Minimum Phase Slow Roll-Off: Nonsymmetrical filter designed to minimize preringing. Strong punchy bass with good transient attacks wave
• Minimum Phase Slow Roll-Off Low Dispersion: Provides a nice balance of the low latency of minimum phase filters and the low dispersion of Linear Phase filters. Minimal preringing is added to achieve the low dispersion in the audio

• Dual Twin Triode KORG Nutube tubes, which were implemented for the first time in Astell & Kern's SP2000T, offering advanced tube sounds.
• When a product is equipped with a Dual DAC, and one vacuum tube must be a separate circuit to convert the signal to balanced right before the output terminal. This structure requires a process to convert an unbalanced signal to a balanced signal, during which, noise gets amplified in the process.
• The CA1000T offers a complete balanced circuit that separates left and right channels with two vacuum tubes, creating even more natural and softer sounds.
• Both Tube AMP mode and OPAMP provide a powerful 15 Vrms output, and the headphone ports allow you to enjoy the unique sounds of vacuum tubes without any limitations.

• The ACRO CA1000T exceeds the standard approach to Amp mode selection based on the type of music you are listening to.
• Select between TUBE AMP mode, OP AMP mode, or the brand-new HYBRID AMP mode.
• OP AMP mode puts Astell & Kern's AMP technology expertise to use, delivering extreme clarity and dynamic sound
• TUBE AMP mode provides a uniquely warm and musical sound.
• HYBRID AMP mode—a first for digital audio players—enhances the resolution and clarity of the existing TUBE AMP mode to express more musical detail.
• HYBRID AMP mode, combines the advantages of retro analog performance and high-resolution output, giving you the pleasure of a brand new tonal characteristic.

• To address the structural issue of vacuum tubes where microphonic noise is created even by the smallest shocks or vibrations, Astell & Kern repeatedly developed new designs and conducted thorough reviews and testing during prototyping.
• Both sides of the vacuum tube are fixed with flexible silicon covers to minimize shocks and a magnetic force is used to physically separate it from the PCB, offering greater stability and isolation when the tube is operational.

• In a headphone environment in which the left and right channels are clearly separated, ear fatigue may increase during prolonged listening.
• Crossfeed mixes parts of the original signal from one channel and sends that signal to the opposite channel with a time difference to center the sound image.
• Through the use of detailed settings such as Shelf Cutoff, Shelf Gain, and Mixer Level, you can set the level of crossfeed according to your listening preferences.

A shield can be applied to prevent various noise and electromagnetic interference from affecting the audio block. The ACRO CA1000T takes it a step further to achieve excellent audio performance and perfect shielding by applying highly conductive high-purity silver on the existing shield can, and by physically separating digital and analog signals.

Q: 6. Can i use this on Black magic cameras??

A: The voltage range of the Blackmagic camera's is 12 to 30 VDC so this battery is a good voltage match. Three things however. 1. There is no known power cable for this. Most likely a custom cable would need to be made. 2. This is very heavy, 11 lbs. You may not want to lug that around all day. 3. This is a heavy duty battery made for older power hungry lights and cameras thus really it is overkill for most uses with the Blackmagic camera's. You might consider Switronics Power Base 70 or this Bescor:Bescor BM-EPIC Battery & Charger for the Blackmagic Camera B&H # BEBCSBMEPIC

Q: 7. Can someone please tell me if this clamp is raised high enough to be placed on a flat surface without the knob getting in the way? I have the DAC-38, and I hate how the locking knob sticks out.

A: No. If you place the clamp on a flat surface, the bottom edge of the knob hits the table and raises the clamp slightly - not by much, but you enough to certainly impede tightening it. You must position it to stick out beyone the edge of whatever you are mounting it on. I also have a larger DAC-X1 and it is the same (worse, actually), although with the way I use them it doesn't matter,

Q: 8. Will this clamp accept the 3 Legged Thing Ellie G bracket?
