Bi-Wiring - JBL 4309 Manuel Du Propriétaire

BI-WIRE AND BI-AMP CONNECTION:
For either bi-wire or bi-amp operation, remove the jumper straps from the terminal cup of the JBL 4309 Studio Monitor
and store in a safe place. Note that removing the straps only disconnects the inputs of the low frequency and high
frequency crossovers from each other, but keeps the full protections and frequency tailoring of the custom crossovers
for the separate driver units.
CAUTION: Do not connect to your speaker in bi-wire or bi-amp fashion with the jumper straps attached.
Severe amplifier damage, personal injury, or damage to other property may result.

Straps from Posts
The 4309 connection assembly has two sets of input terminals that are connected by jumper straps. The upper set of
terminals is for the compression driver, and the lower set of terminals is for the woofer.

BI-WIRING

An amplifier and speaker system are bi-wired when the high frequency and low frequency inputs of the speaker
are driven by two different wires from the same amplifier channel. Usually different types of wire are used for the
connections: a high-current-capability wire or a wire that sounds better to the user for bass is typically used for low
frequencies, and a low-inductance wire or a wire that sounds better for treble to the user is used for high frequencies.
Both wires are connected to the same amplifier output. Some report moderate improvement with this wiring.
To bi-wire the JBL 4309, connect the speakers according to the following illustration.
