to fully drive the amplifiers to maximum output without overdriving the input stage.
Horn Level - This post master volume control adjusts the signal level sent to the high frequency ampli-
fier. Adjust this control to suit your individual taste.
Internal Crossover - Part of what makes this bass combo unique is the built-in asymmetrical bi-amp
crossover. Dividing the signal into low and high frequencies before the amplifiers results in an effective
increase in volume and clarity compared to amplifiers of similar size.
Power Amplifiers - The Series 1 amplifiers utilize new high performance power modules with dynamic
thermal management protection. This exciting process continually monitors all amplifier parameters to
protect itself from faults. These features enable the amplifier to safely operate at a heat sink temperature
of 225 degrees into a shorted load! The low frequency section delivers 130 Watts RMS and the high fre-
quency section delivers 45 Watts RMS and all distortion products are less than 0.1% THD at rated
power.
Under normal operation, the heatsink (finned aluminum device) on the back of the amplifier chassis will
become quite warm to the touch. Care should be exercised not to block this area from free air circula-
tion.
Balanced Line Output - This male 3 pin XLR jack provides a mu-metal shielded transformer isolated bal-
anced output to send to a PA or recording console. The 600 ohm output impedance will easily drive a 20
foot balanced line without signal degradation. A ground lift is provided on the back panel to reduce hum.
The selectable signal source features a DIRECT position that takes the signal from the input jack, feeds
a high impedance buffer amp and the line transformer. None of the amplifiers controls will affect this sig-
nal when the switch is in the direct position. The PRE-AMP position takes the signal immediately AFTER
the master volume control. Since the pre-amp output position is post master volume control, changing
the master volume will also change the pre-amp output of the D.I.
ATTENTION:
Always make sure that you are using a safe grounded receptacle for the specific operation for the volt-
age rated, labeled on the rear of the amplifier. All U.S. models are rated at 115V AC 60Hz.
Always plug the AC power cord into the rear amp receptacle before plugging the cord into a power sup-
ply.
Always use caution against possible hearing loss when operating this unit.
