Page 4: Introduction & Unpacking
1 . 0 I n t r o d u c t i o n & U n p a c k i n g Front panel Rear panel Introduction The PULSE series of amplifiers are high performance professional power amplifiers capable of delivering major power output from a new generation of switched mode power supplies. -
Page 5: Mechanical Installation
2 . 0 Mounting & unit dimensions If the unit is likely to undergo extreme vibration through trucking and touring, front rack ear reinforcement brackets and rear mounting plates must be fitted. These are available from your dealer. Damage caused by insufficient support is not covered by the warranty. -
Page 6: Ac Power Connection
3 . 0 P o w e r C o n n e c t i o n WARNING! THIS APPLIANCE MUST BE GROUNDED. The amplifier must always be connected to a 3-wire grounded AC outlet. The rack framework must also be connected to the same grounding circuit. -
Page 7: Inputs
4 . 0 A u d i o C o n n e c t i o n s Inputs For each channel, there is a 1/4” phone jack socket, male & female XLR and pluggable removable terminal block connectors provided for signal input on the rear panel of the amplifier. Each is electronically balanced at an impedance greater than 10k ohms. -
Page 8: Audio Connections
Outputs ® Both binding post and Speakon connectors are provided for each channel, these are internally wired in parallel so either or both may be used. Note that it is possible to lever the caps out of the ends of the binding posts to insert 4mm banana type plugs but this will invalidate the product safety approvals in some territories. -
Page 9: Control Operation
5 . 0 a. Power Switch Pressing this switch so that the white dot is closest to the front panel signals to the microprocessor that the user wishes to turn on the power supply. Note that the microprocessor will only switch the power supply on once it has assured that there are no internal faults. -
Page 10: Indicators
6 . 0 I n d i c a t o r s A. AC Present This light glows when AC power is applied to the amplifier, whether or not the amplifier is actually running. This light will still glow even if the rear panel fuse is blown because it is powered from the separate, internally fused supply that powers the microprocessor. -
Page 11: Clip
I n d i c a t o r s . . . F. Clip This light is in fact rather more sophisticated than a simple clip indicator; it actually measures distortion. This may occur either due to clipping, trying to drive too low an impedance speaker load or any other mechanism that causes the output of the amplifier channel to not be as expected by the monitoring circuit. -
Page 12: Typical Applications
7 . 0 a. Two channel (stereo) operation In this example, each channel of the PULSE 2x1100 is being used independently. For this application, ensure that the rear panel BRIDGE switches are in the NORMAL position. More than one speaker may be used on each channel as long as the total impedance is not less than 2 ohms. -
Page 13: Two Amplifiers For Stereo With A Mono Sub-Bass
c. Two amplifiers for stereo with a mono sub-bass Here Two amplifiers are used with an active crossover to provide a separate sub-bass signal. d. Calculating Impedance Measured in ohms, impedance is a measure of AC resistance. Loudspeakers generally come in 16, 8 or 4 ohm varieties. -
Page 14: Glossary
8 . 0 G l o s s a r y In this section many of the terms used throughout this manual are explained in more detail. Active Active electronic circuits are those which are capable of voltage and power gain by using transistors and integrated circuits. - Page 15 G l o s s a r y . . . dBu or dBv The addition of a lower case ”u” or “v” after dB indicates an absolute scaling for the dB ratio. 0dBu (or 0 dBv) = 778mV or 0.778 Volts, and it has no regard for power or impedance. This term is widely used for expressing signal voltages in modern audio equipment with high input impedances and low output impedances.
- Page 16 G l o s s a r y . . . Removable terminal block One of the names given to a pluggable terminal block suitable for use with audio where connection to permanent wiring makes their use more suitable than XLR or Jack connectors. Transient A sudden burst of energy in an audio signal which only lasts for a small period of time relative to the rest of the signal.

Are the speakers properly connected? (in particular check that older style ‘ring lock’ type Speakons are rotated in the socket). -
Page 19: Status Indication
T r o u b l e s h o o t i n g . . . Status Indication There is a microprocessor inside each PULSE amplifier responsible for monitoring all critical systems. The status of which are displayed on the front panel lights. Their indication is as follows: Fault and both Temp lights flashing The amplifier has just been plugged in and the microprocessor is carrying out a test sequence. -
