Introduction

E SERIES E 5:4

The E 10:4 has Smart Green Credentials delivering low lifetime cost of ownership.

Features

500 W amplifier carrying 4 flexible output channels in a high power density 1 rack unit form factor saves rack space and system cost
Energy efficient with Energy Star certification for supreme green credentials and exceptionally low lifetime running costs
Flexible IntelliDrive permits delivering the 4 x 125 W at constant voltage 70 V or low impedance (2, 4, 8 and 16 Ohms) on any channel
Asymmetric channel loading allows mixing and matching loads with different impedances to maximize overall system efficiency and inventory utilization
High efficiency amplifier with low power consumption and minimized heat generation lowers demands on the installations’ mains distribution and cooling systems
IDEEA outputs stage based on proprietary, state–of–the–art Class–D amplifier technology for superior performance
Comprehensive fail safe circuit protection ensures continued operation even under reduced operating conditions
Auto–standby and auto–power–on reduces power consumption to below 1 W in non–operating cycles
Rail Sense Limiter (RSL) greatly reduces signal clipping and ensures simple configuration for constant voltage and low impedance loads
Built in 50 Hz high pass filter selectable per channel available on rear panel switch
Per channel attenuation knob and signal LED on rear panel for simple commissioning
Efficient cooling with temperature controlled fans with front to back airflow
Aluminum front panel with power and temperature LEDs and per channel signal and limit LEDs
GPIO connector with power control and indication for further system integration
Balanced high–quality analog inputs and amplifier outputs on detachable screw terminals

The new Aliseo loudspeaker system is the new challenge that Pequod Acoustics has undertaken, designing an elegant system in composite material using the highest quality and specialized 5 “units. The system has an horizontal, symmetrical, and extremely compact design in relation to the performance

ALTANO 18.1

Pequod

The Altano system is a long excursion acoustic suspension subwoofer consisting of 3 12” long–excursion woofers housed in three ovoid volumes structure connected and fused to form an extremely light and rigid monolithic structure. The total power of the system is over 2700 Watts, having high sensitivity (97 dB 1W/1m), with a total radiant surface equivalent to a 21–inch diaphragm.
