The manual was a perfect match and was exactly what I was looking for. I'm very satisfied with my purchase.
;
Thank you for having the manual I needed for an older model Aiwa stero I had found on Ebay --- I wanted the Aiwa because I had tapes and cd's but I did not have a manual as to how to operate the system... I found what I needed and it has enabled me to set the system up for my enjoyment.
;
I wished detailed information of the JBL S310 and here I found it! Very happy with the service from this site!
;
The manual was very helpfull, it answerdes all my questions, and i was surprized to find the original manual on this site! Big thumbs uP:)

EQ: (28 through 34)
The mixer has low shelving, mid peaking and high shelving EQ. �Shelving� means that the circuitry boosts or cuts all frequencies past the specified frequency. For example, boosting the LOW EQ knob boosts bass frequencies at 80Hz and below. �Peaking� means that only a selected �hill� of frequencies surrounding a center �hilltop� frequency is affected by the EQ control. All EQ gain controls provide up to 15dB of boost (clockwise) or cut (counter-clockwise). They are flat (no boost or cut) at their center detents, effectively bypassing their circuits. Note: EQ boost is a form of level boost. With excessive amounts, the signal may become too hot and overload subsequent circuitry. Should this happen, either back off the EQ gain, or repeat the SET THE LEVELS on page 8. The following graphs show how the frequency response changes when the various controls are adjusted.(The graphs are simplified for entertainment and enlightenment purposes only).

Midrange EQ is often considered the most dynamic, because the frequencies that define any sound are almost always found in this range.

34. LOW CUT
This switch (only on the mono channels) cuts the bass frequencies below 75Hz at a rate of 18dB per octave. Low Cut is also known as High Pass (low cut dress=high pass rate). To prevent muddy mixes, use low cut on every mono channel except those which carry kick drum, bass guitar or other bass-intensive sounds. Low cut can also help reduce the possibility of feedback in live situations and it helps to conserve amplifier power.

29. MID and 30. FREQ
The mono channels employ a semiparametric mid-sweep EQ. The gain is set via MID (29), and then �aimed� at a specific frequency, from 100Hz to 8kHz, via FREQ (30).
