LUGGING
N
Due to the nature of passive pickups, the type of cable you use and the input
you plug into will affect the quality of your sound.
INSTRUMENT CABLE
Cable lengths over 10 feet (before preamp) will cause audible high frequency
loss. Use a high quality, low capacitance shielded cable. This will insure min-
imal tone coloration and hum. Using fully shielded metal plugs will also help
eliminate hum.
KINDS OF AUDIO INPUTS
Because of the lack of standardization for high impedance audio inputs, spe-
cial attention should be paid to what you are plugging into:
The BP-100 will sound best when plugged directly into an input with a 10 M
impedance. At 10 M
, the full frequency response of the bass is repro-
duced. The BP-100 can also be plugged into inputs as low as 1 10 M
with
adequate results. At 1 M
, the lowest bass frequencies will be slightly rolled
off.
PREAMPS
We strongly recommend using a 10 M , impedance matching, buffered pre-
amp in conjunction with the pickup.
A matching preamp will:
1. Realize the full frequency response potential of the pickup.
2. Permit long cable runs (after the preamp) without signal deterioration.
3. Allow precise volume and tone shaping with dedicated EQ.
4. Insure compatibility with virtually any instrument level audio input available.
