Frequently Asked Questions - Platinum Series PS600 Bogen

How do I connect a condenser microphone?

Ensure the phantom power switch for the corresponding MIC input (1-4) is set to ON. The amplifier provides 13V DC phantom power.

What should I do if there is no audio output?

Check the LINK switch on the rear panel. It must be in the IN position for normal operation without external signal processing.

How do I set up telephone paging?

Set the MIC 5/TEL switch to TEL. Connect the 600-ohm telephone page source to the screw terminals (Tip and Ring, not center). Adjust the VOX and ALC controls for optimal performance.

Why is my AUX input not muting during a telephone page?

Check the VAR MUTE control setting. It should not be set to 4 (0 dB). Also ensure the VOX threshold is properly adjusted.

What causes the FAULT LED to flash?

Possible causes: over-current (speaker impedance below 8 ohms), high temperature (blocked ventilation), DC voltage on outputs, or high-frequency protection. Check connections and allow cooling.

Can I use the amplifier with 70V speakers?

Yes. The speaker output supports 8 ohm, 25V, and 70V operation. Use appropriate transformers and ensure total power of speaker taps does not exceed 80% of rated amplifier power.

How do I clean the amplifier?

Disconnect power. Clean only with a dry cloth. Do not use liquids or allow moisture to enter the unit.

What is the Audio Enhancement feature?

It regenerates upper harmonics to improve voice intelligibility and presence. Enable via front switch and adjust level with the rear AE control.

How do I adjust the parametric equalizer?

Use the front panel controls: GAIN (boost/cut -15 dB to +15 dB), FREQ (center frequency), and Q (bandwidth). Use the EQ Bypass switch to compare.

What is the warranty period?

Bogen offers a 5-year limited warranty from date of sale to original purchaser covering defects in material or workmanship.

Installation Note

Keep input leads away from the output leads and AC power cables. Unless the driving source provides a low-impedance output, keep the input lead under ten feet in length. Make all connections to the unit with the POWER switch in the OFF position

MIC 1-4 (Rear Panel; #21 and #22)

MIC 1 through 4 utilize female XLR-type microphone connectors. A slide switch located above each XLR connector is used to supply phantom power for condenser microphones.

MIC 5/TEL (Rear Panel; #10 and #11)

The MIC 5/TEL input is designed to accept input from a microphone or from a telephone page port. A slide switch is provided to select MIC 5 or TEL input. To connect a microphone, place the MIC 5/TEL switch in the MIC position. Use two conductor shielded cable and connect the cable shield to the center GND terminal. To use the TEL input, place the MIC 5/TEL switch in the TEL position and connect the 600-ohm telephone paging source (dry signal only - no DC voltage) to the MIC 5/TEL screw terminals.

MIC 6/AUX 1 (Rear Panel; #8, #9, #19)

The MIC 6/AUX 1 input is designed to accept input from a microphone using terminal strip connections or from a line level auxiliary source such as a tuner or CD player using the AUX 1 RCA jack. A slide switch is used to select input type. Connect a microphone to the screw terminals labeled MIC 6 (works only when AUX 1/MIC 6 switch is in the MIC 6 position). Use two conductor shielded cable and connect the cable shield to the center GND terminal. Connect an auxiliary input source to the AUX 1 RCA jack (only works when the AUX 1/MIC 6 switch is in the AUX1 position.)

AUX 2 (Rear Panel; #20)

The AUX 2 input uses an RCA plug and accepts input from a dedicated AUX source.

Remote Volume Control (Rear Panel; #10)

If remote volume control is desired, connect the Bogen accessory GSRVC Remote Volume Control to the screw terminals marked REMOTE MSTR. Wire length can be up to 1000 feet using 22-gauge wire. Connections are not polarity sensitive.

Precedence Connections (Rear Panel; #11)

Precedence connections allow any combination of inputs to be completely muted with a contact closure. Closing a contact across any of the precedence terminals and the PREC COM 1 terminal will mute that input. A customer-supplied normally-open SPST switch, push-to-talk switch, microphone switch, relay or telephone system contact can be used to provide the closure.

Note: Activating the precedence control for AUX inputs completely mutes the input signal. The VAR MUTE control has no effect when muting inputs using precedence control.

Pre-Out/Power Amp In Jacks (Rear Panel; #12, #13, #14)

These jacks permit the insertion of signal processing equipment into the signal path between the preamp output and the power amp input. The LINK switch should be in the IN position for normal operation. When using external signal processing equipment, place the switch in the OUT position and connect PRE OUT to the signal processing equipment's input. Connect the POWER AMP IN to the signal processing equipment's output.

Note: Ensure that the LINK switch is in the IN position when NOT using external signal processing equipment, otherwise there will be no output from the amplifier.

Tape Out (Rear Panel; #15)

The TAPE OUT jack provides a line-level output to feed a recording device. The output is not effected by the Master volume control or EQ, however, the output is affected by the microphone inputs' Lo-Cut filter.

SPKR Out (Rear Panel; #3)

The SPKR OUT provides an amplified speaker level signal intended to drive 8 ohms, 25V, or 70V terminations. Each output pin is driven by the output of an amplifier. Therefore, neither pin of the SPKR terminal can be connected to chassis or Earth ground. Doing so will cause the amplifier to mute the audio and re-main in Protect mode and flash the FAULT LED (page 9) as long as the grounded connection remains.

Direct 8 ohms operation:

Direct 8 ohms operation consists of terminating (without speaker transformers) the amplifier with:

• Two 4-ohm speakers in series
  • One 8-ohm speaker
• Two 16-ohm or four 32-ohm speakers in parallel

Distributed 70V or 25V Operation:

For 70V and 25V operation, use the appropriate 70V or 25V transformers as the installation requires at each speaker. The combined total power across all speaker transformer input taps must not exceed 80% of the rated amplifier power. Also, the total distributed impedance of all transformer inputs must not be less than 8 ohms.

NOTICE

The combined minimum impedance of a 70V/25V/8 ohm system should not be less than 8 ohms. The combined total power of all speaker taps must not exceed 80% of the rated amplifier power for 70V/25V loads.

Power Switch (Rear Panel; #2)

The POWER switch applies power to the unit. An LED labeled ON, which is located on the front panel, illuminates GREEN when power is on.

Individual Volume

Controls (Front Panel; #1- #4)

Each input is controlled by an individual volume control.

Master Volume Control (Front Panel; #8)

The overall volume is controlled by the MASTER volume control.

Lo-Cut Filter (Rear Panel; #7)

The Lo-Cut filter on the rear panel provides low-frequency attenuation on the microphone inputs. This helps reduce mic breath pop, wind noise, and rumble.

Contour Switch (Front Panel; #5)

This switch enables or bypasses the variable loudness contour. This feature only effects the AUX inputs.

This feature is designed to improve richness of sound by restoring the high and low frequencies that the ear is insensitive to at low volume levels. The effect diminishes as volume is increased.

Audio Enhancement

(Front Panel; #9 / Rear Panel; #16)

The front panel Audio Enhancement switch enables or bypasses the Audio Enhancement feature. This feature effects all inputs when enabled.

By regenerating the upper harmonics, this audio enhancement system recreates the presence and realism that is lost in the audio amplification process. This results in increased presence and clarity, increased intelligibility, greater perceived loudness (without using extra power), and reduced listener fatigue.

The rear panel AE adjustment controls the mix of the Audio Enhancement effect with the audio signal. Counterclockwise rotation of the control minimizes the Audio Enhancement effect. Clockwise rotation of the control maximizes the Audio Enhancement effect.

Parametric Equalizer (Front Panel; #6)

A parametric equalizer offers continuous and independent control over the audio signal's frequency content, which is divided into five frequency bands on the Platinum Series amplifiers. These controls are:

• GAIN - The gain (boost/cut) for each frequency band. The gain range for the Platinum Series is -15 dB to ±15 dB as indicated on the GAIN row of controls on the Platinum Series front panel.
• FREQ (Frequency) - The frequency region where the gain boost/cut is desired. The five filter frequency ranges are indicated in the FREQ row of controls on the Platinum Series front panel. Each frequency band is approximately two octaves wide and is constrained within the five control columns on the Platinum Series front panel.
• Q - This is a form of "frequency bandwidth" control centered about the frequency region where the gain boost/cut is desired. Its value is calculated as the ratio of the center frequency to the bandwidth. The filter Q setting is indicated in the Q row of controls on the Platinum Series front panel.

In equalizers, Q is the ratio of center frequency to bandwidth, and if the center frequency is fixed, then bandwidth is inversely proportional to Q—meaning that as you raise the Q, you narrow the bandwidth. For example, if the 1kHz filter is set to 1kHz, the Q will vary from (1618-618)/1000 = 1000/1000 = 1 minimum Q, or maximum bandwidth of 1000 Hz, to 1000/(1051-951) = 1000/100 = 10 maximum Q, or minimum bandwidth of 100 Hz.

Q is the most useful tool a parametric EQ offers, allowing you to boost/cut (with the GAIN control for that frequency band) a very narrow or wide range of frequencies within each EQ band.

A narrow bandwidth (high Q value) is particularly useful for removing unpleasant tones. By notching out the offending frequency, you can remove the problem without removing adjacent frequency content.

A broad bandwidth (low Q value) boosts/cuts (with the GAIN control for that frequency band) a larger band of frequencies. Broad and narrow bandwidths (low and high Q, respectively) are usually used in conjunction with one another to achieve the desired sonic effect.

Variable Mute (Rear Panel; #6)

The VAR MUTE control mutes the AUX input(s) only during telephone pages. The control allows the user to select from 4 levels of muting: 1 = -60 dB, 2 = -21 dB, 3 = -10 dB, 4 = 0 dB.

Telephone Paging Controls & Settings (Front Panel; #3)

The MIC 5/TEL volume control on the front panel controls the volume of the telephone paging input when the control is set to the TEL mode (See page 4 for information on setting the TEL input mode).

The TEL input mode uses voice-activated muting for the AUX inputs and automatic level control for providing constant paging level. To optimize TEL input performance, both the ALC control and the VOX threshold may need to be adjusted.

ALC (Rear Panel; #17)

The TEL input features an automatic level control (ALC) which compensates for different voice levels and speaking styles of the individuals using the system. The amplifier is shipped with this control in the OFF (max. counterclockwise) position.

To adjust the ALC:

1. Rotate the MIC 5/TEL and MASTER controls to the highest level likely to be used.
2. Speak softly and distinctly into the telephone mouthpiece while adjusting the MIC 5/TEL volume control to the desired output level.
3. Speak in a loud voice directly into the telephone mouthpiece while rotating the ALC control clockwise to the point where the output of the amplifier is reduced to the same level as that obtained in Step 2.
4. The MIC 5/TEL and MASTER controls can be used to vary the overall volume without upsetting the ALC adjustment.

VOX (Rear Panel; #18)

The telephone page input features voice-activated AUX muting. This feature always mutes AUX 2 and only mutes AUX 1 when the AUX1/MIC 6 switch is set in that position.

The VOX control should be set so that only the desired signal is above the threshold level, while unwanted noise is below it.

To adjust the sensitivity of the VOX circuit:

1. Rotate the VOX control fully clockwise. While making a public address announcement and talking at a low level, the sound should not be choppy or missing parts of words. If it is choppy or intelligibility is poor, rotate control counterclockwise to the point where the sound is clear and crisp (but not to the maximum counterclockwise position).

2. If the background music shuts down when no page is in progress, rotate the control clockwise until the music will not shut down when no page is in progress.

LEDs (Front Panel; #10)

• FAULT - This flashing LED will indicate a mode where the amplifier is self-protecting. This indication signifies a malfunction. For more information, refer to Amplifier flashes the FAULT LED in the Troubleshooting section.
• LIMIT - This LED indicates full-power output. It also is calibrated at the level where the amplifier's output will no longer increase, even with increasing input, thus the amplifier is limiting its output power level.
• -3 dB - The power-level indicator calibrated at 3 dB down or 1/2 from full power.
• -6 dB - The power-level indicator calibrated at 6 dB down or 1/4 from full power.
• -12 dB - The power-level indicator calibrated at 12 dB down or 1/16th from the amplifier's full power.
• -24 dB - This LED is the beginning of a power-level indicator. Its calibration point is 24 dB down, or 1/256th, from the amplifier's full power output.
• ON - Illuminates green to indicate power is on.

Telephone input is choppy or cuts off the beginning of a page.	Adjust the VOX control counterclockwise to make the trigger activate at a lower input signal level. See page 8.
The telephone page volume is too loud on some pages.	Adjust the ALC control on the rear panel. See page 8.
AUX 1 Input not working.	Make sure MIC 6/AUX 1 switch is in the AUX 1 position.Make sure the signal source is plugged into the AUX 1 RCA jack.
Amplifier flashes the FAULT LED.	There are several causes for the FAULT LED to flash:Over-current.This is usually caused by the total speaker distribution impedance being below 8 ohms, probably due to wiring failure or installation errors.High-temperature.Make sure that the amplifier's vent slots are not blocked and that there is adequate free air flow.DC voltage present on the amplifier outputs. To recover from this condition, turn the power switch off, count to five, and then turn the power switch back on.High-frequency protection.Detection circuitry will cause the amplifier to temporarily protect itself by muting the outputs. There is an automatic reset of the amplifier for this condition.
