1. PASSIVE BASS INSTRUMENT INPUT JACK.
High sensitivity input (55mV). For bass instruments featuring non-active electronics.
Especially suited for older ‘vintage’ basses. This input jack is precisely matched to high
impedance pickups enabling them to faithfully reproduce the true frequency and dynamic
range of the instrument.
2. ACTIVE BASS INSTRUMENT INPUT JACK.
Lower sensitivity input (160mV) for basses with onboard electronics. Input matched for
low signal to noise ratio and optimum transfer function of electrical signal from modern
high-end basses.
3. LINE INPUT.
Input matched to accept high-level outputs from other bass/guitar pre-amps and signals
such as CD players and drum machines. This input is a direct feed to the power amp and
does not pass through limiter or EQ sections.
4. LIMITER ON/OFF SWITCH.
Sends signal through limiter or bypass.
5. COMPRESSION ADJUSTMENT LEVEL.
This will vary the level the limiter threshold. The compression ratio is 3dB to 1. Adjust
this to suit your playing style and output power of instrument.
6. LIMITER INDICATOR.
This L.E.D (Light Emitting Diode) will light up when the signal is being compressed.
This will vary on how hard the instrument is played and how the threshold is adjusted.
7. INPUT LEVEL SENSITIVTY CONTROL.
Just as no two basses are alike, the same goes for players with different styles and
technique. This is a fine-tuning adjustment (+/- 10dB) to get the precise match between
your instrument and the M-500.
8. INPUT LEVEL INDICATOR.
The LED will light up accordingly to the amount of input applied to the amplifier and
therefore gives you the best signal to noise ratio and dynamic range. On normal playing
the blue and green LED will show and occasionally the red LED may light up on peaks.
If the red LED is continuously lighting up, reduce the level on the input sensitivity
control.
9. GRAPHIC EQ ON/OFF SWITCH.
You can switch in or bypass the graphic equalizer circuit with this.
10. GRAPHIC EQ ON INDICATOR.
This will light up blue when you are going through the EQ.
