—out of stock, back in October—
The IOM NCore 500 Stereo is our high-end stereo power amplifier. It was based on the NC500oem board but the NCx500 is de successor of this board.
The 500 Stereo vesion has two NCx500 boards each capable of generating max 700W output power (@ 2 and 4 ohm) . It is housed in a compact full aluminum chassis (5 & 6mm thick sheets) which acts as a one big cooling member. At the back side you will find balanced & unbalanced inputs (selectable) and 4 to 12V trigger input. At the front side a soft touch on/off button with ring light is mounted.
NCx500 with IOM connection board
High-end audio quality is guaranteed by using 2 premium Hypex NCOREx modules (NCx500), this in combination with our connection board or our custom buffer-board .
The connection board set-up makes use of the Hypex NCx500 integrated buffer with on-board op-amps & power supplies. The voltage gain in this set-up is 26.8dB.
Also available is the IOM buffer-board. With this you can purchase and connect the op-amps of your choice (in dip8 or pro 6 pin packages). The gain of the IOM buffer board can be set to 14.6dB or 17.6dB. With a gain of 11.5dB of the NCx500 module in unbuffered mode the total voltage gain of the amplifier is selectable between 26.1dB & 29.1dB.
Two dual op amps are needed for this stereo amplifier. When you want to consider the purchase of the buffer board in a later stage we can on request pre-drill the holes already. Just send an email.
We get a lot of questions about the difference between the connection board and the buffer board & what to use/which to order. The simple answer: the set-up with the connection board uses the on-board op amps on the NCx500 board. Ready for use. Only people who want to swap op amps (now or in the future) should purchase the IOM buffer board. Also ready for use without buying op amps from start but with swapping possibility. The difference of both set-ups is visualized in the next diagram: (buffer boards)
